A Server Control Utility Reference

Use the Server Control Utility (SRVCTL) to manage Oracle Real Application Clusters (Oracle RAC) configuration information.

Note:

SRVCTL commands specific to Oracle Grid Infrastructure administration operations are documented in Oracle Clusterware Administration and Deployment Guide

Note:

A multitenant container database is the only supported architecture in Oracle Database 21c. While the documentation is being revised, legacy terminology may persist. In most cases, "database" and "non-CDB" refer to a CDB or PDB, depending on context. In some contexts, such as upgrades, "non-CDB" refers to a non-CDB from a previous release.

SRVCTL Usage Information

SRVCTL is installed on each node in a cluster by default. To use SRVCTL, log in to the operating system of a node and enter the SRVCTL command and its parameters in case-sensitive syntax.

  • Use the version of SRVCTL that is provided with the current Oracle Database release from the Oracle home of the database that you are managing. The version of SRVCTL must be the same as the version of the object (listeners, Oracle ASM instances, Oracle Database, Oracle Database instances, and Oracle Database services) being managed.

  • SRVCTL does not support concurrent executions of commands on the same object. Therefore, run only one SRVCTL command at a time for each database, service, or other object.

  • When specifying a comma-delimited list as part of a SRVCTL command, there should not be any spaces between the items in the list. For example:

    srvctl add database -serverpool "serverpool1,serverpool3"

    When you specify a comma-delimited list in a Windows environment, you must enclose the list in double quotation marks (""). You can enclose a comma-delimited list in double quotation marks in a Linux or UNIX environment but they will be ignored.

  • If you are entering a SRVCTL command, and you want to continue the input on a new line, then you can use the operating system continuation character. In Linux, this is the backslash (\) symbol.

  • A SRVCTL command that produces no output is a successful command. Not all SRVCTL commands return a message when it completes, successfully. However, if a SRVCTL command fails, then it always returns an error message.

  • SRVCTL returns 0 on success, 1 on failure, and 2 on warnings. Some commands, such as start, stop, enable, and disable, can return 2 for a warning when the request would not change anything. In other words, the object of the command is already started, already stopped, already disabled, and so on. In warning cases, SRVCTL also prints a message about what was already done.

  • You can use the -eval parameter with several SRVCTL commands. This parameter, when you use it, enables you to simulate running a command without making any changes to the system. SRVCTL returns output that informs you what will happen if you run a particular command. For example, to know what might happen if you relocate a server: 

    $ srvctl relocate server –servers "rac1" –eval –serverpool pool2

Database db1
     will stop on node rac1
     will start on node rac7
     Service mySrv1
          will stop on node rac1, it will not run on any node
     Service myServ2
          will stop on node rac1
          will start on node rac6
Server rac1
     will be moved from pool myPoolX to pool pool2

    The -eval parameter is available with the following commands:

    • srvctl add database

    • srvctl add service

    • srvctl add srvpool

    • srvctl modify database

    • srvctl modify service

    • srvctl modify srvpool

    • srvctl relocate server

    • srvctl relocate service

    • srvctl remove srvpool

    • srvctl start database

    • srvctl start service

    • srvctl stop database

    • srvctl stop service

Specifying Command Parameters as Keywords Instead of Single Letters

The use of single letter commands is deprecated. Oracle recommends that you use full command words with SRVCTL.

In releases earlier than Oracle Database 12c, the SRVCTL command-line interface used single letter parameters. However, single letter parameters impose a limit on the number of unique parameters available for use with SRVCTL commands. SRVCTL command parameters in current Oracle Database releases use full words instead of single letters, such as -multicastport and -subdomain.

To support backward compatibility, you can use a mix of single-letter parameters and new keyword parameters. New parameters introduced with keywords can be used with single letter parameters.

Note:

The use of single letter parameters are deprecated. Oracle recommends that you use the keyword parameters, so that you avoid using the same letter to implement different functionality, depending on the command.

You can obtain the single-letter equivalents, where applicable, by adding the -compatible parameter after the -help parameter.

Using SRVCTL Help

Learn about how to use context sensitive help with SRVCTL commands.

To see help for all SRVCTL commands, from the command line enter:

srvctl -help

To see the command syntax and a list of parameters for each SRVCTL command, from the command line enter:

srvctl command (or verb) object (or noun) -help

When you request online help for a command using -help, SRVCTL prints the full words for each parameter. You can obtain the single-letter equivalents, where applicable, by adding the -compatible parameter after the -help parameter. For example: 

$ srvctl config database -help -compatible

The preceding command prints usage information for the srvctl config database command, listing all parameters as full words followed by their single-letter equivalents in parentheses, where applicable.

To see the SRVCTL version number enter:

$ srvctl -version

SRVCTL Privileges and Security

To use SRVCTL to change your Oracle RAC database configuration, log in to the operating system as the software owner of the home that you want to manage.

For example, if different users installed Oracle Database and the Oracle Grid Infrastructure, then log in as the database software owner (for example, ora_db) to manage databases and log in as the Oracle Grid Infrastructure software owner (for example, ora_asm) to manage the Oracle ASM instances.

Users who are members of the OSDBA operating system group can start and stop the database. To stop and start an Oracle ASM instance, you must be a member of the OSASM operating system group.

To create or register objects such as listeners, Oracle Notification Services, and services, you must be logged in to the operating system as the software owner of the Oracle home. The objects you create or register for that Oracle home will run under the user account of the owner of the Oracle home. Databases run as the database installation owner of the home from which they run.

To perform srvctl add operations on any object, you must be logged in as the Oracle account owner of the home on which the object runs.

For some SRVCTL commands, to run the commands on Linux and Unix systems, you must be logged in as root, and on Windows systems, you must be logged in as a user with Administrator privileges. In this appendix, those commands are preceded by the root prompt (#) in the command examples.

Additional SRVCTL Topics

You can use SRVCTL to manage Oracle-supplied resources, but Oracle strongly advises you to follow the guidelines provided here.

  • Use SRVCTL to manage Oracle-supplied resources such as listener, instances, disk groups, and networks, and CRSCTL for managing Oracle Clusterware and its resources.

    Caution:

    Oracle strongly discourages you from using CRSCTL to directly manipulate Oracle-supplied resources (resources whose names begin with ora). Making manual changes to Oracle resources using CRSCTL can adversely affect the cluster configuration.

  • Although you may be able to cancel running SRVCTL commands by pressing the Control-C keys, Oracle strongly advises that you do not attempt to do this, because you can corrupt your configuration data by doing this.

    Do not to attempt to terminate SRVCTL in this manner.

Deprecated SRVCTL Subprograms or Commands

Oracle recommends that you use alternatives for several SRVCTL commands and parameters deprecated with Oracle Database 12c.

Parent topic: Server Control Utility Reference

Single Character Parameters Deprecated for all SRVCTL Commands

Single-character parameters were deprecated in Oracle Database 12c. Use the full keyword for each parameter. Refer to the information here to understand how to update scripts using single-character parameters.

Oracle recommends that you use the full keyword for each SRVCTL parameter. To support older tools and scripts that still use single-character parameters, the current version of SRVCTL continues to support both single-character parameters and full keyword parameters. However, deprecated functionality can be desupported in a future release.

The command reference topics for SRVCTL show the keywords for each SRVCTL command. The following table lists the deprecated single-character parameters.

About Using SRVCTL Commands

To be able to use SRVCTL commands to obtain the outcome you require, review these guidelines.

SRVCTL commands, object names, and parameters are case-sensitive. Database, instance, listener, and service names are case insensitive and case preserving. You cannot create listener names that differ only in case, such as LISTENER and listener. SRVCTL uses the following command syntax:

srvctl command object [parameters]

In SRVCTL syntax:

  • command is a verb, such as start, stop, or remove

  • object (also known as a noun) is the target or object on which SRVCTL performs the command, such as database or instance. You can also use object abbreviations.

  • parameters extend the use of a preceding command combination to include additional parameters for the command. For example, the -instances parameter indicates that a comma-delimited list of preferred instance names follows; the -instance parameter only permits one value and not a list of names. Do not use spaces between the items in a comma-delimited list.

Note:

If specifying a comma-delimited list in Windows, then you must enclose the list within double quotation marks ("").

The following table lists the keywords that you can use for the object portion of SRVCTL commands. You can use either the full name or the abbreviation for each object keyword. The Purpose column describes the object and the actions that can be performed on that object.

Table A-4 Object Keywords and Abbreviations

     [-defaultnetnum network_number] [-verbose]

Parameters

Table A-5 srvctl add database Command Parameters

Parameter Description
-db db_unique_name

The unique name of the database.
-oraclehome oracle_home

The path for the Oracle database home directory.
-dbtype {RACONENODE | RAC | SINGLE}

The type of database you are adding: Oracle RAC One Node, Oracle RAC, or single instance. The default is RAC. If you specify the -node node_name parameter, then the -dbtype parameter defaults to SINGLE.

-server server_list

List of candidate servers for Oracle RAC One Node databases.

Note: If your Oracle RAC One Node database is policy managed, then you cannot use this parameter.

-instance instance_name

The instance name prefix for Oracle RAC One Node databases. The default value for this parameter is the first 12 characters of the global unique name of the database.

Note: If your Oracle RAC One Node database is policy managed, then you cannot use this parameter.

-timeout timeout

The online database relocation timeout, in minutes, for Oracle RAC One Node databases. The default value is 30.

-domain db_domain

The domain for the database.

Note: You must use this parameter if you set the DB_DOMAIN initialization parameter for the database.

-spfile spfile

The path name of the database server parameter file.
-pwfile password_file_path

The full path to the location of the password file.
-role {PRIMARY | PHYSICAL_STANDBY | LOGICAL_STANDBY | SNAPSHOT_STANDBY | FAR_SYNC}

The role of the database in an Oracle Data Guard configuration. The default is PRIMARY.

-startoption start_options

Startup options for the database, such as OPEN, MOUNT, and NOMOUNT. The default value is OPEN.

Notes:
  • For multi-word startup options, such as read only and read write, separate the words with a space and enclose in double quotation marks (""). For example, "read only".
  • When performing a switchover in an Oracle Data Guard configuration, the -startoption for a standby database that becomes a primary database is always set to OPEN after the switchover.
-stopoption stop_options

Stop options for the database, such as NORMAL, TRANSACTIONAL, IMMEDIATE, and ABORT.

-startconcurrency start_concurrency

Number of instances to be started simultaneously, or 0 to disable this option.
-stopconcurrency stop_concurrency

Number of instances to be stopped simultaneously, or 0 to disable this option.
-dbname db_name

The name of the database, if it is different from the unique name given by the -db parameter.

-policy {AUTOMATIC | MANUAL | NORESTART | USERONLY | RANK}

The management policy for the database.

  • AUTOMATIC (default): The database is automatically restored to its previous running condition (started or stopped) upon restart of the database host computer.
  • MANUAL: The database is never automatically restarted upon restart of the database host computer. A MANUAL setting does not prevent Oracle Clusterware from monitoring the database while it is running and restarting it if a failure occurs.
  • NORESTART: Similar to the MANUAL setting, the database is not automatically restarted upon restart of the database host computer. A NORESTART setting, however, does not restart the database, even if a failure occurs, unless it must be started for dependencies, such as services or PDBs.
  • USERONLY: The database can only be restarted by user command, not as a result of any other reason (auto-start, start by dependency, node failure, and so on.)
  • RANK: The database won't be restarted when the Oracle Clusterware stack is restarted unless it is restarted by start dependencies of its PDBs that are started according to RANK. For example, 2 CDBs have policy set to RANK and their PDBs have policy set to RESTART. If a PDB of CDB1 has a rank of 3 and a PDB in CDB2 has a rank of 2, and if there are only enough resources to start one CDB, then CDB1 will be started by dependency when its PDB is started. CDB2 is not started because its PDB has a lower rank number.
-node node_name

The node name on which you want to register a noncluster, or single instance, Oracle database.

Note: This parameter can be used only with Oracle Clusterware.

-diskgroup "disk_group_list"

A comma-delimited list of Oracle Automatic Storage Management (Oracle ASM) disk groups if database uses Oracle ASM storage.

-acfspath "acfs_path_list"

A single Oracle ASM Cluster File System (Oracle ACFS) path or a comma-delimited list of Oracle ACFS paths enclosed in double quotation marks ("") where the database's dependency is set.

Use this parameter to create dependencies on Oracle ACFS file systems other than ORACLE_HOME, such as for when the database uses ORACLE_BASE on a file system that is different from the ORACLE_HOME file system.

-eval

Use this parameter to hypothetically evaluate the impact of the command on the system.

Note: You can only use this parameter with a policy-managed database. Starting with Oracle Database 21c, policy-managed databases are deprecated.

-css_critical {YES | NO}

You can add weight to a service by setting this parameter to YES. In the event of a node failure within the cluster, Oracle Clusterware will evict the node with the least amount of weight, ensuring that critical services remain available.

Note: You cannot use this parameter with policy-managed databases or nodes.

-memorytarget memory_target

The target memory size, in MB, to be allocated for the database. The default is 0.
-maxmemory max_memory

The maximum memory size, in MB, to be allocated for the resource. If you specify -memorytarget but not -maxmemory, then -maxmemory will default to 0. Both -maxmemory and -memorytarget are validated as long as -memorytarget is less than or equal to -maxmemory.

-defaultnetnum network_number

Specify a network number (an integer) to which services will default in the event you do not specify a network number when you add the service. The number must match the value of the -netnum parameter you specified when you added the network.

Examples

This example shows how to add a database named crm.example.com in a specific Oracle Home directory. 

$ srvctl add database -db crm -oraclehome /u01/oracle/product/21c/mydb 
-domain example.com

The management policy for the database.

  • AUTOMATIC (default): The database is automatically restored to its previous running condition (started or stopped) upon restart of the database host computer.
  • MANUAL: The database is never automatically restarted upon restart of the database host computer. A MANUAL setting does not prevent Oracle Clusterware from monitoring the database while it is running and restarting it if a failure occurs.
  • NORESTART: Similar to the MANUAL setting, the database is not automatically restarted upon restart of the database host computer. A NORESTART setting, however, does not restart the database, even if a failure occurs, unless it must be started for dependencies, such as services or PDBs.
  • USERONLY: The database can only be restarted by user command, not as a result of any other reason (auto-start, start by dependency, node failure, and so on.)
  • RANK: The database won't be restarted when the Oracle Clusterware stack is restarted unless it is restarted by start dependencies of its PDBs that are started according to RANK. For example, 2 CDBs have policy set to RANK and their PDBs have policy set to RESTART. If a PDB of CDB1 has a rank of 3 and a PDB in CDB2 has a rank of 2, and if there are only enough resources to start one CDB, then CDB1 will be started by dependency when its PDB is started. CDB2 is not started because its PDB has a lower rank number.
-diskgroup "disk_group_list"

Comma-delimited list of Oracle ASM disk groups if database uses Oracle ASM storage.
-acfspath "acfs_path_list"

A single Oracle ACFS path or a comma-delimited list of Oracle ACFS paths enclosed in double quotation marks ("") where the database's dependency is set.

Use this parameter to create dependencies on Oracle ACFS file systems other than ORACLE_HOME, such as for when the database uses ORACLE_BASE on a file system that is different from the ORACLE_HOME file system.

-css_critical {YES | NO}

You can add weight to a service by setting this parameter to YES. In the event of a node failure within the cluster, Oracle Clusterware will evict the node with the least amount of weight, ensuring that critical services remain available.

Note: You can use this parameter only on an administrator-managed node. Should the node become policy managed, at some point, this parameter will no longer apply.

-memorytarget memory_target

Specify the target memory, in MB, to be allocated for the database. The default is 0.
-maxmemory max_memory

Specify the maximum memory, in MB, to be allocated for the resource. If you specify -memorytarget but not -maxmemory, then -maxmemory will be the default value of 0. Both -maxmemory and -memorytarget are validated as long as -memorytarget is less than or equal to -maxmemory.

-defaultnetnum network_number

Specify a network number to which services will default in the event you do not specify a network number when you add a service.
-disabledreason {DECOMMISSIONED}

Marks the database as being decommissioned, which means it cannot be started again and is not being used. This is intended for databases that will be deleted at a future date.
-eval

Use this parameter to hypothetically evaluate the impact of the command on the system.

Note: You can only use this parameter with a policy-managed database.

Usage Notes

  • When using the srvctl modify database command, for a running database, if the server list is supplied, then the node where the database is running must be on that list.

  • The instance name prefix cannot be modified after running the srvctl add database command.

  • You cannot change the management policy from AUTOMATIC (using the -policy parameter) for Oracle RAC One Node databases. Any attempt to do so results in an error message.

Examples

The following example changes the role of a database to a logical standby:

$ srvctl modify database -db crm -role logical_standby

The following example directs the racTest database to use the SYSFILES, LOGS, and OLTP Oracle ASM disk groups: 

$ srvctl modify database -db racTest -diskgroup "SYSFILES,LOGS,OLTP"
srvctl predict database

  • Optionally, you can use the –verbose parameter to display detailed output.

Parent topic: database Commands

srvctl relocate database
Initiates the relocation of an Oracle RAC One Node database from one node to another node.

This command also cleans up after a failed relocation, and you can only use it for relocating Oracle RAC One Node databases.

Syntax

Use this command with one of the following syntax models:

To initiate the online relocation of an Oracle RAC One Node database:

srvctl relocate database -db db_unique_name [-node target_node] [-timeout timeout]
   [-stopoption NORMAL] [-drain_timeout drain_timeout] [-verbose]

To abort the failed online relocation of an Oracle RAC One Node database:

srvctl relocate database -db db_unique_name -abort [-revert] 
   [-drain_timeout drain_timeout] [-verbose]

Parameters

Table A-13 srvctl relocate database Command Parameters

Parameter Description
-db db_unique_name

Specify the unique name of the database you want to relocate.
-node target_node

Optionally, you can specify a target node to which to relocate the Oracle RAC One Node database.

Note: You must use this parameter if you are relocating an administrator-managed Oracle RAC One Node database.

-timeout timeout

Optionally, you can specify an online database relocation timeout, in minutes, for Oracle RAC One Node databases. The default is 30.

-stopoption NORMAL

Use this parameter to override the default shutdown option for a running instance, such as the default of SHUTDOWN TRANSACTIONAL LOCAL for a primary database or SHUTDOWN IMMEDIATE for a standby database. The only value accepted for -stopoption is NORMAL.

–abort

Use this parameter to abort a failed online database relocation.
–revert

Use this parameter to remove the target node of a failed online relocation request from the candidate server list of an administrator-managed Oracle RAC One Node database.
-drain_timeout timeout

Specify the time, in seconds, allowed for resource draining to be completed. Accepted values are an empty string (""), 0, or any positive integer. The default value is an empty string, which means that this parameter is not set. If it is set to 0, then draining occurs, immediately.

The draining period is intended for planned maintenance operations. During the draining period, all current client requests are processed, but new requests are not accepted. When set on the service this value is used when the command line value is not set.
–verbose

Use this parameter to display verbose output.

Usage Notes

  • If the Oracle RAC One Node database you want to relocate is not running, then the command returns an error.

  • If another online database relocation is active for this Oracle RAC One Node database, then the command returns an error.

  • If the -drain_timeout value is higher than the -timeout value, then SRVCTL relocates the services but does not explicitly start or stop the services on the database instances.

  • If an online database relocation for this Oracle RAC One Node database has failed and the target nodes are not the same for either relocation, then the command returns an error instructing you to abort the failed online database relocation and then initiate a new one.

  • If an online database relocation for this Oracle RAC One Node database has failed and the target nodes are the same (or you do not specify the target), then the command attempts to relocate the database.

Example

The following example relocates an administrator-managed Oracle RAC One Node database named rac1 to a server called node7. 

$ srvctl relocate database -db rac1 -node node7

srvctl start database
Starts a database and its enabled instances, and all listeners on nodes with database instances.

You can disable listeners that you do not want to start.

Syntax

srvctl start database -db db_unique_name [-eval] [-startoption start_options]
  [-stopconcurrency number_of_instances] [-node node_name]

Parameters

Table A-16 srvctl start database Command Parameters

Parameter Description
-db db_unique_name

Specify the unique name of the database you want to start.
–eval

Optionally, use this parameter to hypothetically evaluate the impact of the command on the system.
-startoption start_options

Optionally, you can set options for the startup command (for example: OPEN, MOUNT, or NOMOUNT).

Notes:

  • This command parameter supports all database startup options.

  • For multi-word startup options, such as read only and read write, separate the words with a space and enclose in double quotation marks (""). For example, "read only".

    See Also: SQL*Plus User's Guide and Reference for more information about startup options

-stopconcurrency number_of_instances

Optionally, you can specify a number of database instances to start simultaneously, or specify 0 for an empty start concurrency value.

-node node_name

Optionally, you can specify the name of a node on which you want to start the database.

Notes:

  • This command only applies to Oracle RAC One Node and Standard Edition High Availability databases.

  • The node you specify must be in the candidate list for an administrator-managed Oracle RAC One Node or Standard Edition High Availability database. The node must be in the server pool for a policy-managed Oracle RAC One Node database.

  • If the database is already running on a node than the one you specify, then the command returns an error.

  • If you do not specify a node, then Oracle Clusterware chooses which node on which to start the Oracle RAC One Node or Standard Edition High Availability database according to its policies, such as dispersion, number of resources, and order of candidate nodes.

  • If there is an active online database relocation for the Oracle RAC One Node database you are attempting to start, then both instances will already be running and the command returns an error message. Only during an online database relocation are two instances of an Oracle RAC One Node database in existence.

    If the online database relocation failed for the Oracle RAC One Node database and you do not specify a node, then the command attempts to start both database instances.

    If the online database relocation failed for the Oracle RAC One Node database and you specify a node, then the command attempts to abort the failed relocation and start the instance on that node.

Examples

The following example starts the crm database and sets the startup option to read only: 

$ srvctl start database -db crm -startoption "read only"

Syntax

srvctl stop database -db db_unique_name [-stopoption stop_options] 
  [-stopconcurrency number_of_instances] [-drain_timeout timeout] [-eval]
  [-force] [-verbose]

Parameters

Table A-18 srvctl stop database Command Parameters

Parameter Description
-db db_unique_name

Specify the unique name for the database that you want to stop.
-stopoption stop_options

Optionally, you can specify options for the shutdown command, such as NORMAL, TRANSACTIONAL LOCAL, IMMEDIATE, or ABORT.

-stopconcurrency number_of_instances

Optionally, you can specify a number of database instances to stop simultaneously, or specify 0 for an empty stop concurrency value.

-drain_timeout timeout

Optionally, you can specify the time, in seconds, allowed to complete the resource draining action. By default, this parameter is not set. You can specify 0 or any positive integer. An empty string unsets the parameter. If you specify zero, then the agent will perform the actions related to service draining, immediately.

Drain timeout is the maximum time the service waits before exiting (in case of srvctl stop service or srvctl stop instance) or proceeding to stop database (srvctl stop database), until the draining of sessions is completed. If session draining completes in 10 seconds and the drain timeout value (on CLI or resource attribute) is 100 seconds, then SRVCTL moves on after 10 seconds. It does not wait for the remaining 90 seconds.

-eval

Optionally, you can use this parameter to hypothetically evaluate the impact of the command on the system.
-force

Optionally, you can use this parameter to stop the database, its instances, its services, and any resources that depend on those services.
—verbose

  [/{TCPS|SDP|EXADIRECT}port_list[:FIREWALL={ON|OFF}]]" [-group group_name]] [-invitednodes "node_list"]
  [-invitedsubnets "subnet_list"] [-skip]

To create a SCAN listener, use the srvctl add scan_listener command.

Parameters

Table A-36 srvctl add listener Command Parameters

Parameter Description
-listener listener_name

Specify a listener name. This parameter is optional.

If you do not specify this parameter, then the name of the listener defaults to LISTENER for a database listener or LISTENER_ASM for an Oracle ASM listener.

-netnum network_number

The optional network number from which VIPs are obtained. If not specified, the VIPs are obtained from the same default network from which the nodeapps VIP is obtained.

Note: Use this parameter when you add an Oracle Database listener.

-oraclehome oracle_home

Specify an Oracle home for the cluster database. If you do not include this parameter, then SRVCTL uses the Grid home by default.

Note: Use this parameter when you add an Oracle Database listener.

-user user_name

Use this parameter to set the user that will run the listener to a less privileged user. Oracle recommends using this parameter to increase security.

Notes:

  • You must be logged in as root to run this command and specify the -user parameter.

  • Use this parameter when you add an Oracle Database listener.

  • When you use the -user parameter, ensure the following:

    The listener log directory in the Oracle Base directory and the Grid_home/network/admin/user_name directory must both exist on each node before you can use this parameter. Additionally, user_name must have read, write, and execute permission in the directory.

    The Oracle_Base/diag/tnslsnr/host_name/lower_case_listener_name directory exists and user_name has read, write, and execute permission on it.

  • Before you can use LSNRCTL to manage a listener, you must set TNS_ADMIN to Grid_home/network/admin/user_name.

-endpoints "[TCP:]port_list[:FIREWALL={ON|OFF}][/IPC:key] [/NMP:pipe_name][/{TCPS|SDP|EXADIRECT}port_list[:FIREWALL={ON|OFF}]]"]

Protocol specifications for the listener. Use port_list to specify a comma-delimited list of TCP ports or listener endpoints.

If you do not specify the -endpoints parameter for an Oracle Database listener, then SRVCTL searches for a free port between 1521 and 1540.

You can also specify endpoints for TCPS, SDP, and EXADIRECT ports.

Note: You can modify this attribute using Online Resource Attribute Modification.

-group group_name

Optionally, you can use the -group parameter with -endpoints to specify a group for the secure endpoint. This parameter is used for the EXADIRECT protocol on Exadata and Exalogic systems.
-invitednodes "node_list"

Specify a comma-delimited list of node names allowed to register with the listener.
-invitedsubnets "subnet_list"

Specify a comma-delimited list of subnets allowed to register with the listener.
-skip

Indicates you want to skip the checking of ports.
-asmlistener

Specifies the listener type as an Oracle ASM listener. If you do not specify the -listener parameter, then the name of the Oracle ASM listener defaults to LISTENER_ASM.

Note: You can only use this parameter with Oracle Clusterware.

-subnet subnet

Specifies the subnet to use for an Oracle ASM listener.

Note: You can only use this parameter with Oracle Clusterware.

Usage Notes

You must run this command as root user on Linux and UNIX platforms when you specify the -user parameter.

Example

The following command adds a listener named listener112 that is listening on ports 1341, 1342, and 1345 and runs from the Oracle home directory on every node in the cluster. 

$ srvctl add listener -listener listener112 -endpoints "1341,1342,1345" 
-oraclehome /u01/app/oracle/product/21.0.0/db1

When a listener is configured in the Oracle RAC home instead of the Grid home, then the listener.ora file is created under the location returned by the $ORACLE_HOME/bin/orabasehome utility, in the subdirectory network/admin, for example, /u02/racbase/homes/OraDB21Home1/network/admin.

network Commands

Use commands with the network keyword to add, modify, list the configuration of, and remove a non-default Network.

Parent topic: SRVCTL Command Reference

srvctl add network

Adds a static or dynamic network.

If your server connects to more than one network, then you can use this command to configure an additional network interface for Oracle RAC, allowing you to create VIPs on multiple public networks.

Syntax

srvctl add network [-netnum net_number] -subnet subnet/netmask[/if1[|if2...]]
   [-nettype {STATIC | DHCP | AUTOCONFIG | MIXED}] [-pingtarget "ping_target_list"] 
   [-skip] [-verbose]

Parameters

Table A-47 srvctl add network Command Parameters

Parameter Description
-netnum net_number

The network number. The default is 1.
-subnet subnet/netmask [/if1[|if2|...]]

Defines a subnet. If you do not specify any interface names, then the network uses any interface on the given subnet.

For IPv6, netmask is a prefix length, such as 64.

-nettype {STATIC|DHCP|AUTOCONFIG|MIXED}

Specify the network type: STATIC, DHCP, AUTOCONFIG, or MIXED.

If you specify STATIC for the network type, then you must provide the virtual IP address using the srvctl add vip command.

If you specify DHCP for the network type, then the VIP agent obtains the IP address from a DHCP server.

If you specify AUTOCONFIG for the network type, then the VIP agent generates a stateless IPv6 address for the network. You can only use AUTOCONFIG for IPv6 networks. If the subnet/netmask specification is not for an IPv6 address, then SRVCTL returns an error.

If you specify MIXED for the network type, then the VIP resource uses both a static IP address and an IP address obtained dynamically, either from a DHCP server for IPv4 or using stateless auto-configuration for IPv6.

-pingtarget "ping_target_list"

A comma-delimited list of IP addresses or host names to ping.
-skip

Use this parameter to skip the checking of subnet.
-verbose

Verbose output.

Usage Notes

  • On Linux and UNIX systems, you must be logged in as the root user and on Windows, you must be logged in as a user with Administrator privileges to run this command.

  • This command is only available with Oracle Clusterware.

  • Oracle only supports DHCP-assigned networks for the default network, not for subsequent networks.

  • You can also use the LISTENER_NETWORKS database initialization parameter to control client redirects to the appropriate network.

Example

An example of this command is:

# srvctl add network -netnum 3 -subnet 192.168.3.0/255.255.255.0

Parent topic: network Commands

srvctl config network

Parent topic: network Commands

srvctl modify network
Modifies the subnet, network type, or IP address type for a network.

Syntax

srvctl modify network [-netnum network_number] [-subnet subnet/netmask
  [/if1[|if2|...]]] [-nettype network_type | -iptype {ipv4 | ipv6 | both}]
  [-pingtarget "ping_target_list"] [-verbose]

Parameters

Table A-48 srvctl modify network Command Parameters

Parameter Description
-netnum network_number

Optionally, you can specify a network number that you want to modify. The default is 1.
-subnet subnet/netmask [/if1[|if2|...]]

Optionally, you can specify a subnet number for the public network. The netmask and interfaces you specify, if any, change those of the network you are modifying. If you specify an IPv6 subnet, then enter a prefix length, such as 64, in place of netmask. If you do not specify any interface names, then the VIPs use any interface on the given subnet.

If you are changing the network type using the -nettype parameter, then you must specify either an existing IPv4 or IPv6 network using the -subnet parameter. Additionally, the subnet and netmask you specify in the -subnet parameter do not change those of the network you are modifying.

-nettype network_type Optionally, you can modify the network type using this parameter, to static, dhcp, autoconfig, or mixed.
-iptype {ipv4 | ipv6 | both}

Alternative to modifying the network type, you can modify the type of IP address to ipv4, ipv6, or both.

-pingtarget "ping_target_list"

Optionally, you can specify a comma-delimited list of IP addresses or host names to ping enclosed in double quotation marks ("").

-verbose

Optionally, you can use this parameter to display detailed output.

Usage Notes

  • You can only use this command with Oracle Clusterware.

  • On Linux and UNIX systems, you must be logged in as root and on Windows, you must be logged in as a user with Administrator privileges to run this command.

  • You can modify the IP address type for a network from IPv4 to IPv6, or from IPv6 to IPv4.

  • If you specify static for the network type, then you must provide the virtual IP address using the srvctl add vip command.

  • If you specify dhcp for the network type, then the VIP agent obtains the IP address from a DHCP server.

  • If you specify autoconfig for the network type, then the VIP agent generates a stateless IPv6 address for the network. You can only use this parameter for IPv6 networks. If the subnet/netmask specification is not for an IPv6 address, then SRVCTL returns an error.

  • If you change a network from static to mixed, then you must first configure GNS, so that the dynamic addresses obtained can have names registered for them.

  • If you specify mixed for the network type, then the VIP resource uses both a static IP address and an IP address obtained dynamically, either DHCP or autoconfig.

  • If you specify mixed_autoconfig for the network type, then the VIP resource retains the static IP configuration and either obtains an IP address from a DHCP server for an IPv4 network specification or generates a stateless auto-configured IP address for an IPv6 network specification.

Examples

The following example changes the subnet number, netmask, and interface list:

# srvctl modify network -subnet 192.168.2.0/255.255.255.0/eth0

The following example changes the second network to DHCP:

# srvctl modify network -netnum 2 -nettype dhcp

The following example adds an IPv6 subnet and netmask to the default network:

# srvctl modify network -subnet 2606:b400:400:18c0::/64

The following example removes the IPv4 configuration from a network:

# srvctl modify network -iptype ipv6
srvctl predict network

-mincpuunit min_cpu_usage

The minimum CPU usage limit for the PDB.
-approot approot_database

The application root PDB.
-startoption start_options

Startup options for the PDB, such as OPEN or OPEN READ ONLY. The default value is an empty string, which means the PDB uses the same open mode as the CDB.

Note:

For multi-word startup options, such as read only and read write, separate the words with a space and enclose in double quotation marks (""). For example, "read only".

-stoption stop_options

Stop options for the PDB, such as NORMAL. The default stop option is IMMEDIATE.

-policy policy

Management policy for the pluggable database, where policy can be one of the following values:

Modifies the number of SCAN VIPs to match the number of IP addresses returned by looking up the scan_name you specify in DNS.

You use this command when DNS was modified to add, change, or remove IP addresses, and now you must adjust the Oracle Clusterware resource configuration to match.

Syntax

srvctl modify scan -scanname scan_name [-netnum network_number]

Parameters

Table A-74 srvctl modify scan Command Parameters

Parameter Description
-scanname scan_name

Identifies the SCAN name that resolves to the SCAN VIPs that you want to modify.

Note: You can modify this attribute using Online Resource Attribute Modification.

-netnum network_number

The optional network number from which VIPs are obtained. If not specified, the VIPs are obtained from the same default network from which the nodeapps VIP is obtained.

Example

Assume your system currently has a SCAN named scan_name1, and it resolves to a single IP address in DNS. If you modify the SCAN scan_name1 in DNS to resolve to three IP addresses, then use the following command to create the additional SCAN VIP resources: 

$ srvctl modify scan -scanname scan_name1

Parent topic: scan Commands

srvctl predict scan
Predicts the consequences of SCAN failure.

Syntax

srvctl predict scan -scannumber ordinal_number [-verbose]

Usage Notes

  • Specify an ordinal number that identifies the SCAN VIP for which you want to simulate failure. The range of values you can specify for this parameter is 1 to 3.

  • Optionally, you can use the –verbose parameter to display detailed output.

Parameters

The following table lists and describes all the srvctl add service parameters and whether they can be used when adding a service to either an Oracle RAC database or non-cluster database.

Table A-89 srvctl add service Command Parameters

Parameter Description
-db db_unique_name

Unique name for the database.
-service service_name_list

The service_name.service_domain should be unique within the cluster unless you want to spread connections across multiple databases that offer the same service. If you do not specify the service domain as part of the service name (such as sales.example.com), then the DB_DOMAIN database attribute is appended to the service name. You can specify one service or several services in a comma-delimited list.

Note: The -service parameter has a 4 kilobyte (KB) limit for its value. Therefore, the total length of the names of all services assigned to an instance cannot exceed 4 KB.

-cardinality {UNIFORM | SINGLETON | DUPLEX}

The cardinality of the service, which can be one of the following:

  • UNIFORM – offered on all instances or PDBs in the database
  • SINGLETON – runs on only one instance or PDB at a time
  • DUPLEX – runs on two instances or PDBs at a time
Notes:
  • This parameter can be used only with Oracle RAC.
  • For policy-managed Oracle RAC One Node databases, all services must be SINGLETON.
-preferred "preferred_list"

A comma-separated list of preferred instances on which the service runs.

The list of preferred instances must be mutually exclusive with the list of available instances.

Note: This parameter can be used only with Oracle RAC and cannot be used with policy-managed databases.

-available "available_list"

A comma-separated list of available instances to which the service fails over.

The list of available instances must be mutually exclusive with the list of preferred instances.

Note: This parameter can be used only with Oracle RAC and cannot be used with policy-managed databases.

-tafpolicy {BASIC|NONE}

Transparent Application Failover (TAF) policy specification (cannot be used with policy-managed databases).
-serverpool server_pool

The name of a server pool used when the database is policy managed.

Notes:
  • This parameter can be used only with Oracle RAC and only for policy-managed databases.
  • Starting with Oracle Grid Infrastructure 21c, policy-managed databases are deprecated.
-netnum network_number

Use this parameter to determine on which network this service is offered. The service is configured to depend on VIPs from the specified network.

Notes:
  • If you omit this parameter, then the default is taken from the database configuration, which you specify using srvctl add database or srvctl modify database, with the -defaultnetwork parameter to specify the default network for that database's services.
  • This parameter can be used only with Oracle RAC and Oracle RAC One Node database configurations.
-role "[PRIMARY][,PHYSICAL_STANDBY] [,LOGICAL_STANDBY][,SNAPSHOT_STANDBY]"

The service role. You can specify one or more roles in a comma-delimited list.

Use this option to indicate that the service should only be automatically started upon database open when the Oracle Data Guard database role matches one of the specified service roles.

Using SRVCTL to manually start a service is not affected by the service role.

Note: The -role parameter is only used at database startup and by the Oracle Data Guard Broker. All manual service startup must specify the name of the service to be started by the user.

-policy {AUTOMATIC | MANUAL}

Service management policy.

If AUTOMATIC (the default), then the service is automatically started upon restart of the database, either by a planned restart (with SRVCTL) or after a failure. Automatic restart is also subject to the service role, however (the -role parameter).

If MANUAL, then the service is never automatically restarted upon planned restart of the database (with SRVCTL). A MANUAL setting does not prevent Oracle Clusterware from monitoring the service when it is running and restarting it if a failure occurs.

Note: Using CRSCTL to stop and start the Oracle Clusterware restarts the service in the same way that a failure does.

-notification {TRUE | FALSE}

Enable Fast Application Notification (FAN) for OCI connections.
-dtp {TRUE | FALSE}

Indicates whether Distributed Transaction Processing should be enabled for this service. This service will either be a singleton service in a policy-managed database or a preferred service on a single node in an administrator-managed database.
-clbgoal {SHORT | LONG}

Connection Load Balancing Goal. Use a value of SHORT for this parameter for run-time load balancing, or if using an integrated connection pool. Use a value of LONG for this parameter for long running connections, such as batch jobs, that you want balanced by the number of sessions per node for the service.

-rlbgoal {NONE | SERVICE_TIME | THROUGHPUT}

Runtime Load Balancing Goal (for the Load Balancing Advisory). Set this parameter to SERVICE_TIME to balance connections by response time. Set this parameter to THROUGHPUT to balance connections by throughput.

-resetstate {NONE | LEVEL1}

Reset state in a session to clean values. If set to NONE, then session state is not cleaned. If set to LEVEL1, then session states that cannot be restored are reset.

The session state reset excludes global SYS CONTEXT and secure roles.
-failovertype {NONE | SESSION | SELECT | TRANSACTION | AUTO}

Set the failover type.

To enable Application Continuity for Java, set this parameter to TRANSACTION. To enable Transparent Application Continuity, set this parameter to AUTO.

To enable TAF for OCI, set this parameter to SELECT or SESSION.

Note: If you set -failovertype to TRANSACTION, then you must set -commit_outcome to TRUE.

-failovermethod {NONE | BASIC}

TAF failover method (for backward compatibility only).

If the failover type (-failovertype) is set to a value other than NONE, then you should choose BASIC for this parameter.

Note: This parameter can be used only with Oracle RAC.

-failoverretry failover_retries

For Application Continuity and TAF, this parameter determines the number of attempts to connect after an incident.
-failoverdelay failover_delay

For Application Continuity and TAF, this parameter specifies the time delay (in seconds) between reconnect attempts per incident at failover.
-failover_restore {NONE|LEVEL1|AUTO}

For Application Continuity, when you set the -failover_restore parameter, session states are restored before replaying. Use LEVEL1 for ODP.NET and Java with Application Continuity to restore the initial state.

Set this parameter to AUTO to enable Transparent Application Continuity to restore session states.

For OCI applications using TAF or Application Continuity, setting -failover_restore to LEVEL1 restores the current state. If the current state differs from the initial state, then a TAF callback is required. This restriction applies only to OCI.

-failback {YES | NO} If a service fails over to an available instance after the list of preferred instances was exhausted, then, if this parameter is set to YES, the service automatically fails back to a preferred instance when one becomes available.
-edition edition_name

The initial session edition of the service.

When an edition is specified for a service, all subsequent connections that specify the service use this edition as the initial session edition. However, if a session connection specifies a different edition, then the edition specified in the session connection is used for the initial session edition.

SRVCTL does not validate the specified edition name. During connection, the connect user must have USE privilege on the specified edition. If the edition does not exist or if the connect user does not have USE privilege on the specified edition, then an error is raised.

-pdb pluggable_database

The name of the pluggable database (PDB).

You can specify a PDB property when you create or modify a service. The PDB property associates the service with the specified PDB. You can view the PDB property for a service by querying the ALL_SERVICES data dictionary view or, when using the SRVCTL utility, by running the srvctl config service command.

Note: Starting with Oracle Database 21c, before using the -pdb option with the srvctl add service command, you must have previously added the PDB resource to Oracle Clusterware using the srvctl add pdb command.

-global {TRUE | FALSE}

Indicates whether this is a Global Data Services service.

Note: This parameter can only be used with Global Data Services.

-maxlag maximum_lag_time

Maximum replication lag time in seconds for a global service. Must be a non-negative integer. The default value is ANY. You must also specify the -global option.

-sql_translation_profile profile_name

Use this parameter to specify a SQL translation profile for a service that you are adding after you have migrated applications from a non-Oracle database to an Oracle database.

This parameter corresponds to the SQL translation profile parameter in the DBMS_SERVICE service attribute.

Notes:
  • Before using the SQL translation feature, you must migrate all server-side application objects and data to the Oracle database.
  • Use the srvctl config service command to display the SQL translation profile.
-commit_outcome {TRUE | FALSE}

Enable Transaction Guard; when set to TRUE, the commit outcome for a transaction is accessible after the transaction's session fails due to a recoverable outage.

-retention retention_time

If -commit_outcome is set to TRUE, then this parameter determines the amount of time (in seconds) that the commit outcome is retained in the database.

-replay_init_time replay_initialization_time

For Application Continuity, this parameter specifies the difference between the time, in seconds, of original execution of the first operation of a request and the time that the replay is ready to start after a successful reconnect. Application Continuity will not replay after the specified amount of time has passed. This parameter is intended to avoid the unintentional execution of a transaction when a system is recovered after a long period. The default is 5 minutes (300). The maximum value is 24 hours (86400). If the -failover_type parameter is not set to TRANSACTION, then you cannot use this parameter.

-session_state {STATIC | DYNAMIC | AUTO}

For Application Continuity; this parameter describes how the non-transactional session state is changed by the application within a request. Examples of session state are NLS settings, optimizer preferences, event settings, PL/SQL global variables, and temporary tables. For Transparent Application Continuity session_state is always set to AUTO. Session state is tracked automatically.

This parameter is considered only if -failovertype is set to TRANSACTION for Application Continuity or AUTO for Transparent Application Continuity.

  • If failover_type is set to TRANSACTION, then Oracle recommends a value of DYNAMIC for session_state.
  • If failover_type is set to AUTO, then session_state defaults to AUTO.
  • If failover_type is set to any value other than TRANSACTION or AUTO, then the value of session_state is not set.

If non-transactional values change after the request starts, then set this parameter to either DYNAMIC or AUTO. Most applications should use DYNAMIC or AUTO mode.

-pqservice pq_service

Specify a parallel query service name.
-pqpool pq_pool

Specify a parallel query server pool.
-gsmflags gsm_flags

Set locality and region failover values for a global service. You must also specify the -global option.

-tablefamilyid table_family_id

Set table family ID for a service. See "Shared Table Family" for more information.

-drain_timeout timeout

Specify the time, in seconds, allowed for resource draining to be completed. Accepted values are an empty string (""), 0, or any positive integer. The default value is an empty string, which means that this parameter is not set. If it is set to 0, then draining occurs, immediately.

The draining period is intended for planned maintenance operations. During the draining period, all current client requests are processed, but new requests are not accepted. When set on the service this value is used when the command line value is not set.
-stopoption {NONE|IMMEDIATE|TRANSACTIONAL}

Specify the default method of stopping the service. When set on the service, this value is used if you do not include the -stopoption parameter in other SRVCTL commands. If you do not set provide a value, then the default option NONE is used.

  • IMMEDIATE permits sessions to drain before the service is stopped. Sessions that do not drain are terminated when the time limit specified by -drain_timeout is reached.
  • If you specify TRANSACTIONAL, then sessions are terminated as soon as they commit. The service is stopped when the time limit specified by -drain_timeout is reached and any remaining sessions are terminated.
  • If you specify NONE, then no sessions are terminated.
-css_critical {yes | no}

You can add weight to a service by setting this parameter to YES. In the event of a node failure within the cluster, Oracle Clusterware will evict the node with the least amount of weight, ensuring that critical services remain available.

-rfpool pool_name

Specify the name of the reader farm server pool.
-update {-preferred new_preferred_instance | -available new_available_instance}

Add a new preferred or available instance to the service configuration. -preferred specifies the name of the instance to add to the list of preferred instances for the service. -available specifies the name of the instance to add to the list of available instances for the service.

-force

Force the add operation even though a listener is not configured for a network.
-eval

Use this parameter to hypothetically evaluate the impact of the command on the system.
-verbose

Display verbose output.

Usage Notes

This command does not accept placement parameters for Oracle RAC One Node databases.

Examples

Use this example syntax to add the gl.example.com service to the my_rac database with Fast Application Notification enabled for OCI connections, a failover method of BASIC, a Connection Load Balancing Goal of LONG, a failover type of SELECT, and 180 failover retries with a failover delay of 5 seconds: 

$ srvctl add service -db my_rac -service gl.example.com -notification TRUE -failovermethod BASIC 
-failovertype SELECT -failoverretry 180 -failoverdelay 5 -clbgoal LONG

Use this example syntax to add a named service to a database with preferred instances and available instances and enabled for TAF:

$ srvctl add service -db crm -service sales -preferred crm01,crm02 -available crm03 -tafpolicy BASIC

srvctl disable service
Disables a service.

Disabling an entire service affects all of the instances, disabling each one. If the entire service is already disabled, then running this command on the entire service returns an error. This means that you cannot always use the entire set of service operations to manipulate the service indicators for each instance.

Syntax

srvctl disable service -db db_unique_name -services "service_name_list"
   [-instance instance_name | -node node_name]

Parameters

Table A-91 srvctl disable service Command Parameters

Parameter Description
-db db_unique_name

Specify a unique name for the database for which you want to disable the service.
-services "service_name_list"

Specify a comma-delimited list of service names enclosed in double quotation marks (""), or a single service name, that you want to disable.

-instance instance_name

Optionally, you can specify the name of the instance for which you want to disable the service.

Notes:

  • Use this parameter with administrator-managed databases.

  • You can only use this parameter with Oracle Clusterware and Oracle RAC.
-node node_name

Alternative to using the –instance parameter, you can use this parameter to specify the name of the node on which to disable the service.

Notes:

  • Use this parameter with policy-managed databases.

  • You can only use this parameter with Oracle Clusterware and Oracle RAC.

Examples

The following example globally disables two services for the CRM database: 

$ srvctl disable service -db crm -service "crm,marketing"

The following example disables a service for the CRM database that is running on the CRM1 instance, resulting in the service still being available for the database, but on one less instance: 

$ srvctl disable service -db crm -service crm -instance crm1

Parent topic: service Commands

srvctl enable service
Enables a service for Oracle Clusterware.

Enabling an entire service also affects the enabling of the service over all of the instances by enabling the service on each one. If the entire service is already enabled, then running this command does not affect all of the instances and enable them but, instead, returns an error. Therefore, you cannot always use the entire set of service operations to manipulate the service indicators for each instance.

Syntax

srvctl enable service -db db_unique_name -service "service_name_list"
   [-instance instance_name | -node node_name]

Parameters

Table A-92 srvctl enable service Command Parameters

Parameter Description
-db db_unique_name

Specify a unique name for the database for which you want to enable the service.
-service "service_name_list"

Specify a single service name or a comma-delimited list of service names enclosed in double quotation marks ("") that you want to enable.

-instance instance_name

Optionally, you can use this parameter to specify the name of the database instance where you want the service to run.

Notes:

  • Use this parameter for administrator-managed databases.

  • You can only use this parameter with Oracle Clusterware and Oracle RAC.
-node node_name

Alternative to using the –instance parameter, you can use this parameter to specify the name of the node on which to enable the service.

Notes:

  • Use this parameter with policy-managed databases.

  • You can only use this parameter with Oracle Clusterware and Oracle RAC.

Examples

The following example globally enables a service:

$ srvctl enable service -db crm -service crm

The following example enables a service to use a preferred instance:

$srvctl enable service -db crm -service crm -instance crm1

Parent topic: service Commands

srvctl modify service

Modifies a service configuration.

Starting with Oracle Grid Infrastructure 21c, policy-managed databases are deprecated.

This command supports some online modifications to the service, such as:

  • Moving a service member from one instance to another

  • Performing online changes to service attributes from DBMS_SERVICE (for example, failover delay, runtime load balancing goal, and so on)

  • Adding a new preferred or available instance

  • Removing preferred or available instances for a service

Caution:

Oracle recommends that you limit configuration changes to the minimum requirement and that you not perform other service operations while the online service modification is in progress.

Syntax and Parameters

Use one of the following forms of the srvctl modify service command, depending on the task you want to perform, with the specified syntax:

To move a service from one instance to another:

srvctl modify service -db db_unique_name -service service_name 
      -oldinst old_instance_name -newinst new_instance_name [-force]

Note:

This form of the command is only available with Oracle Clusterware.

Table A-93 srvctl modify service Parameters for Moving a Service

Parameter Description
-db db_unique_name

Specify the unique name for the database.
-service service_name

Specify a service name. If you do not specify a service name, then SRVCTL moves all services.
-oldinst old_instance_name

Specify the name of the instance from which you want to move the service.
-newinst new_instance_name

Specify the name of the instance to which you want to move the service.
-force

Force the modify operation, stopping the service on some nodes, as necessary.

To change an available instance to a preferred instance for a service:

srvctl modify service -db db_unique_name -service service_name 
      -available avail_inst_name [-failback {YES|NO}] -toprefer [-force]

Note:

This form of the command is only available with Oracle Clusterware and does not accept placement parameters for Oracle RAC One Node databases. This command also does not move or otherwise disconnect the service but only modifies the service attributes.

Table A-94 srvctl modify service Parameters for Changing to a Preferred Instance

Parameter Description
-db db_unique_name

Specify the unique name for the database.
-service service_name

Specify the name of the service you want to modify.
-available available_inst_name

Specify the name of the available instance you want to change.
-failback {YES|NO} If a service fails over to an available instance after the list of preferred instances was exhausted, then, if this parameter is set to YES, then the service automatically fails back to a preferred instance when one becomes available.
-toprefer

Specify this parameter to change the instance status to preferred.
-force

Force the modify operation. For planned operations, the user experience is best if using an Oracle Connection Pool with FAN. The FAN planned event causes the Oracle pool to drain the requests with no interruption to the users.

To change the available and preferred status for multiple instances:

srvctl modify service -db db_unique_name -service service_name 
     -modifyconfig -preferred "preferred_list" [-available "available_list"]
     [-force]

Note:

This form of the command is only available with Oracle Clusterware and does not accept placement parameters for Oracle RAC One Node databases. This command also does not move or otherwise disconnect the service but only modifies the service attributes.

Table A-95 srvctl modify service Parameters for Changing Status of Multiple Instances

Parameter Description
-db db_unique_name

Specify the unique name for the database.
-service service_name

Specify the name of the service you want to modify.
-modifyconfig

This parameter directs SRVCTL to use only the instances named for this service (unnamed instances already assigned to the service are removed).
-preferred "preferred_instance_list"

Specify a comma-delimited list of preferred instances enclosed within double quotation marks ("").
-available "available_instance_list"

Specify a comma-delimited list of available instances enclosed within double quotation marks ("").
-force

Force the modify operation. For planned operations, the user experience is best if using an Oracle Connection Pool with FAN. The FAN planned event causes the connection pool to drain the requests with no interruption to the users.

Table A-96 srvctl modify service Parameters

Parameter Description
-db db_unique_name

The unique name for the database.
-service service_name

The name of the service you want to modify.
-serverpool pool_name

The name of a server pool used when the database is policy managed.

Note: This parameter can be used only with Oracle RAC and only for policy-managed databases.

-pqservice pqsvc_name

A comma-delimited list of parallel query service names.
-pqpool pq_pool_list

A comma-delimited list of parallel query server pool names.
-cardinality {UNIFORM|SINGLETON|DUPLEX}

The cardinality of the service, which can be one of the following:

  • UNIFORM – offered on all instances or PDBs in the database
  • SINGLETON – runs on only one instance or PDB at a time
  • DUPLEX – runs on two instances or PDBs at a time
Notes:
  • This parameter can be used only with Oracle RAC.
  • For policy-managed Oracle RAC One Node databases, all services must be SINGLETON.
-tafpolicy {BASIC|NONE}

Transparent Application Failover (TAF) policy specification (cannot be used with policy-managed databases).
-role "[PRIMARY][,PHYSICAL_STANDBY] [,LOGICAL_STANDBY][,SNAPSHOT_STANDBY]"

The database modes for which the service should be started automatically. You can specify one or more roles in a comma-delimited list.

Note: The -role parameter is only used at database startup and by the Oracle Data Guard Broker. All manual service startup must specify the name of the service to be started by the user.

-policy {AUTOMATIC|MANUAL}

The service management policy.

If AUTOMATIC (the default), then the service is automatically started upon restart of the database, either by a planned restart (with SRVCTL) or after a failure. Automatic restart is also subject to the service role, however (the -role parameter).

If MANUAL, then the service is never automatically restarted upon planned restart of the database (with SRVCTL). A MANUAL setting does not prevent Oracle Clusterware from monitoring the service when it is running and restarting it if a failure occurs.

-notification {TRUE|FALSE}

Use TRUE to enable Fast Application Notification (FAN) for Oracle Call Interface (OCI) connections.

-dtp {TRUE|FALSE}

Use TRUE to enable Distributed Transaction Processing for this service. This ensures that the service is offered at exactly one instance at a time for XA affinity.

Note: This parameter can be used only with Oracle RAC.

-clbgoal {SHORT|LONG}

Connection Load Balancing Goal. Set to SHORT if using runtime load balancing, or set to LONG for long running connections, such as batch jobs, that you want balanced by the number of sessions per node for the service.

-rlbgoal {NONE|SERVICE_TIME|THROUGHPUT}

Runtime Load Balancing Goal (for the Load Balancing Advisory). Set this parameter to SERVICE_TIME to balance connections by response time. Set this parameter to THROUGHPUT to balance connections by throughput.

-resetstate {NONE | LEVEL1}

Reset state in a session to clean values. If set to NONE, then session state is not cleaned. If set to LEVEL1, then session states that cannot be restored are reset.

-failovertype {NONE|SESSION|SELECT|TRANSACTION|AUTO}

Use this parameter to set the failover type.

To enable Application Continuity, set this parameter to TRANSACTION. To enable Transparent Application Continuity, set this parameter to AUTO.

To enable TAF, set this parameter to SELECT or SESSION.

-failoverretry failover_retries

For Application Continuity and TAF, specify the number of attempts to connect after an incident.
-failoverdelay failover_delay

For Application Continuity and TAF, specify the time delay (in seconds) between reconnect attempts per incident at failover.
-failover_restore [NONE|LEVEL1|AUTO]

For Application Continuity, when you set the -failover_restore parameter, session states are restored before replaying. Use LEVEL1 for ODP.NET and Java with Application Continuity to restore the initial state.

Set this parameter to AUTO to enable Transparent Application Continuity to restore session states.

For OCI applications using TAF or Application Continuity, setting -failover_restore to LEVEL1 restores the current state. If the current state differs from the initial state, then a TAF callback is required. This restriction applies only to OCI.

-failback {YES | NO} If a service fails over to an available instance after the list of preferred instances was exhausted, then, if this parameter is set to YES, the service automatically fails back to a preferred instance when one becomes available.
-edition edition_name

The initial session edition of the service.

When an edition is specified for a service, all subsequent connections that specify the service use this edition as the initial session edition. However, if a session connection specifies a different edition, then the edition specified in the session connection is used for the initial session edition.

SRVCTL does not validate the specified edition name. During connection, the connect user must have USE privilege on the specified edition. If the edition does not exist or if the connect user does not have USE privilege on the specified edition, then an error is raised.

-pdb pluggable_database

The name of a pluggable database (PDB).

Note: You can specify a PDB property when you create or modify a service. The PDB property associates the service with the specified PDB. You can view the PDB property for a service by querying the ALL_SERVICES data dictionary view or, when using the SRVCTL utility, by running the srvctl config service command.

When create or modify a service with the specified PDB, SRVCTL does not check if the PDB exists. Before running this command, you must ensure that the PDB exists.
-sql_translation_profile profile_name

Use this parameter to specify a SQL translation profile for a service that you are modifying after you have migrated applications from a non-Oracle database to an Oracle database.

If you want to set the SQL translation profile to a NULL value, then you must enter an empty string after the -p flag.

Note: Before using the SQL translation feature, you must migrate all server-side application objects and data to the Oracle database.

-commit_outcome {TRUE|FALSE}

Enable Transaction Guard; when set to TRUE, the commit outcome for a transaction is accessible after the transaction's session fails due to a recoverable outage.

-retention retention_time

For Transaction Guard (with the -commit_outcome parameter set to TRUE); this parameter determines the amount of time (in seconds) that the commit outcome is retained in the database.

-replay_init_time replay_initiation_time

For Application Continuity; this parameter specifies the time, in seconds, from when the original request started. Application Continuity will not replay after the specified amount of time has passed. This attribute avoids the unintentional replay of a request when a system is recovered after a long period. The default value is 300 (5 minutes).
-session_state {STATIC|DYNAMIC|AUTO}

For Application Continuity; this parameter describes how the non-transactional session state is changed by the application within a request. Examples of session state are NLS settings, optimizer preferences, event settings, PL/SQL global variables, and temporary tables. For Transparent Application Continuity session_state is always set to AUTO. Session state is tracked automatically.

This parameter is considered only if -failovertype is set to TRANSACTION for Application Continuity or AUTO for Transparent Application Continuity.

  • If failover_type is set to TRANSACTION, then Oracle recommends a value of DYNAMIC for session_state.
  • If failover_type is set to AUTO, then session_state defaults to AUTO.
  • If failover_type is set to any value other than TRANSACTION or AUTO, then the value of session_state is not set.

Oracle recommends a value of AUTO or DYNAMIC for most applications. If you are unsure which value to use, or if you can customize the application, then use DYNAMIC.
-maxlag maximum_lag_time

Maximum replication lag time in seconds for a global service. Must be a non-negative integer. The default value is ANY. You must also specify the -global option.

-gsmflags gsm_flags

Set locality and region failover values for a global service. You must also specify the -global option.

-tablefamilyid table_family_id

Set table family ID for a service. See Sharded Table Family for more information.

-drain_timeout timeout

Specify the time, in seconds, allowed for resource draining to be completed. Accepted values are an empty string (""), 0, or any positive integer. The default value is an empty string, which means that this parameter is not set. If it is set to 0, then draining occurs, immediately.

The draining period is intended for planned maintenance operations. During the draining period, all current client requests are processed, but new requests are not accepted. When set on the service this value is used when the command line value is not set.
-stopoption {NONE|IMMEDIATE|TRANSACTIONAL}

Specify the method of stopping the service. If this attribute was previously set for the service, then that value is used as the default value if you do not include the -stopoption parameter in your command. Otherwise, the default is NONE.

  • IMMEDIATE permits sessions to drain before the service is stopped. Sessions that do not drain are terminated when the time limit specified by -drain_timeout is reached.
  • If you specify TRANSACTIONAL, then sessions are terminated as soon as they commit. The service is stopped when the time limit specified by -drain_timeout is reached and any remaining sessions are terminated.
  • If you specify NONE, then no sessions are terminated.

Note: You must use the -stopoption parameter with the -force parameter.
-global_override

Override value to modify the global service attributes.

Use this parameter with the -role, -policy, -notification, -failovertype, -failovermethod, -failoverdelay, -failoverretry and -edition parameters.

-css_critical {yes | no}

You can add weight to a service by setting this parameter to YES. In the event of a node failure within the cluster, Oracle Clusterware will evict the node with the least amount of weight, ensuring that critical services remain available.

Note: You cannot use this parameter with policy-managed databases.

-rfpool pool_name

Specify the name of the reader farm server pool.
-eval

Use this parameter to hypothetically evaluate the impact of the command on the system.

Note: You can only use this parameter with a policy-managed service.

–verbose

Display verbose output.
-force

Force the modify operation, stopping the service on some nodes as necessary.

Usage Notes

  • When performing online changes to service attributes (for example, failover delay, Runtime Load Balancing Goal, and so on), the changes take effect only when the service is next (re)started.

  • When a service configuration is modified so that a new preferred or available instance is added, the running state of the existing service is not affected. However, the newly added instances will not automatically provide the service, until a srvctl start service command is issued.

  • When there are available instances for the service, and the service configuration is modified so that a preferred or available instance is removed, the running state of the service may change unpredictably:

    • The service is stopped and then removed on some instances according to the new service configuration.

    • The service may be running on some instances that are being removed from the service configuration.

    • These services will be relocated to the next free instance in the new service configuration.

Because of these considerations, when the online service is being modified, users may experience a brief service outage on some instances even if the instances are not being removed. Or users may experience a brief service outage on instances that are being removed from the service.

Examples

An example of moving a service member from one instance to another is:

$ srvctl modify service -db crm -service crm -oldinst crm1 -newinst crm2

An example of changing an available instance to a preferred instance is:

$ srvctl modify service -db crm -service crm -available crm1 -toprefer

The following command exchanges a preferred and available instance:

$ srvctl modify service -db crm -service crm -modifyconfig -preferred "crm1" \
-available "crm2"
srvctl predict service
Predicts the consequences of service failure.

Syntax

srvctl predict service -db db_unique_name -service service_name [-verbose]

Parameters

-pdb pluggable_database

The name of the pluggable database in which the service you want to relocate is currently running.
-oldinst old_inst_name

The name of the instance from which you are relocating the service.
-newinst new_inst_name

The name of the instance to which you are relocating the service. This parameter is optional. If you do not specify an instance, then Oracle Clusterware chooses a new one.

Note: If you are using an administrator-managed database, then you must use the -oldinst and -newinst parameters and the target instance must be on the preferred or available list for the service.

Starting with Oracle Grid Infrastructure 21c, policy-managed databases are deprecated.
-currentnode source_node

Name of the node where the service is currently running.
-targetnode target_node

Name of node where the service is to be relocated. If you do not specify a target node, then Oracle Clusterware chooses a new location.

Note: If you are using a policy-managed database, then you must use the -currentnode and -targetnode parameters.

Starting with Oracle Grid Infrastructure 21c, policy-managed databases are deprecated.
-drain_timeout timeout

Specify the time, in seconds, allowed for resource draining to be completed. Accepted values are an empty string (""), 0, or any positive integer. The default value is an empty string, which means that this parameter is not set. If it is set to 0, then draining occurs, immediately.

The draining period is intended for planned maintenance operations. During the draining period, all current client requests are processed, but new requests are not accepted. When set on the service this value is used when the command line value is not set.
-wait YES | NO

Choose YES to wait until service draining is completed on the node from which you are relocating the service.

-stopoption option

Specify the method of stopping the service. If this attribute was previously set for the service, then that value is used as the default value if you do not include the -stopoption parameter in your command. Otherwise, the default is NONE.

  • IMMEDIATE permits sessions to drain before the service is stopped. Sessions that do not drain are terminated when the time limit specified by -drain_timeout is reached.
  • If you specify TRANSACTIONAL, then sessions are terminated as soon as they commit. The service is stopped when the time limit specified by -drain_timeout is reached and any remaining sessions are terminated.
  • If you specify NONE, then no sessions are terminated.

Note: You must use the -stopoption parameter with the -force parameter.
–pq

Performs the action on a parallel query service.

srvctl remove service

Removes the service from Oracle Clusterware management.

Syntax

srvctl remove service -db db_unique_name {-service service_name |
   -pdb pdb_name}[-global_override] [-force]

Parameters

Table A-99 srvctl remove service Command Parameters

Parameter Description
-db db_unique_name

The unique name of the database or container database.
-service service_name

The name of the service you want to remove. You must specify either the service name or the pluggable database (PDB) name.

-pdb pdb_name

The name of the PDB that offers the service. You must specify either the service name or the PDB name.

-global_override

Indicates you are modifying global services. SRVCTL ignores this parameter for a non-global service.
-force

Ignore any dependencies when removing the service.

Usage Notes

If you use the -pdb option with this command, then SRVCTL removes all service resources for the specified PDB, but does not remove the PDB resource. If you specify the PDB service name using the -service option, then you do not have to also include the -pdb option because the PDB service name is unique within the container database (CDB).

Examples

This following example removes the sales service from all instances of the clustered database named crm: 

$ srvctl remove service -db crm -service sales

The following example removes the services from the crmeast PDB: 

$ srvctl remove service -db crm -pdb crmeast

srvctl start service

Starts a service or multiple services on a database, pluggable database, or instance.

Syntax

srvctl start service [-db db_unique_name] [-service "services_list"
  [-pq] | -pdb pluggable_database | -serverpool pool_name]
  [-node node_name | -instance instance_name]
  [-global_override] [-startoption start_options] [-eval] [-verbose]

Parameters

Parameter Description
-db db_unique_name

Specify a unique name for the database.
-service "service_list"

Specify a service name or a comma-delimited list of service names enclosed in double quotation marks ("").

If you do not include this parameter, then SRVCTL starts all of the services for the specified database.

Note: All manual service startup must specify the name of the service to be started by the user.

-pq

Specify this parameter to restrict the start action to a parallel query service.
-pdb pluggable_database

Specify the name of a pluggable database. Optionally, you can specify either the name of a node or the name of an instance to restrict the starting of services to that particular object on the pluggable database.
-serverpool pool_name

Alternative to using the -pq parameter, you can specify the name of a server pool that contains the services you want to start. Use this parameter for policy-managed databases.

-node node_name

Specify the name of a node where the services reside that you want to start. Use this parameter for policy-managed databases.
-instance instance_name

Specify the name of an instance where the services reside that you want to start. Use this parameter for administrator-managed databases.
-global_override

Override value to operate on a global service. Use this parameter only with global services; this parameter is ignored if specified for a non-global service.
-startoption start_options

Specify startup options used when service startup requires starting a database instance. Options include OPEN, MOUNT, and NOMOUNT.

Note: For multi-word startup options, such as read only and read write, separate the words with a space and enclose in double quotation marks (""). For example, "read only".

–verbose

Display verbose output.

Usage Notes

  • The srvctl start service command will fail if you attempt to start a service that is already running.

  • The srvctl start service command will fail if you attempt to start a service on an instance, if that service is already running on its maximum number of instances, that is, its number of preferred instances.

  • You can move a service or change the status of a service on an instance with the srvctl modify service and srvctl relocate service commands.

Examples

The following example starts all services on a specific database:

$ srvctl start database -db myDB

The following examples start a list of services (optionally restricted to a parallel query services in the latter example) regardless of the pluggable database on which they may reside:

$ srvctl start database -db myDB -service "myServ01,myServ02"
$ srvctl start database -db myDB -service "myServ01,myServ02" -pq

The following example starts all services in a given server pool:

$ srvctl start database -db myDB -serverpool myServerPool

The following examples start all services on a given pluggable database, optionally restricted to a single node or a single instance in the latter two examples, repectively:

$ srvctl start service -db myDB -pdb myPDB1
$ srvctl start service -db myDB -pdb myPDB1 -node myRACNode01
$ srvctl start service -db myDB -pdb myPDB1 -instance myDB01

The following example starts all services, for a given database, on a given instance (for all pluggable databases):

$ srvctl start service -db myDB -instance myDB01

The following example start all services for a given database on a given node (for all pluggable databases):

$ srvctl start service -db myDB -node myRACNode01

The following examples start a list of services on a given node or given instance:

$ srvctl start service -db myDB -service "myService01,myService02" -node myRACNode01
$ srvctl start service -db myDB -service "myService01,myService02" -instance myDB01

srvctl stop service

Stops one or more services globally across the cluster database, or on the specified instance.

Syntax

To stop services for a particular node in the cluster:

srvctl stop service -node node_name [-stopoption IMMEDIATE|TRANSACTIONAL|NONE] 
   [-drain_timeout timeout] [-wait {YES | NO}] [-force] [-noreplay]
   [-global_override] [-verbose]

To stop services for a database:

srvctl stop service -db db_unique_name [-pq] [-rf] [-pdb pluggable_database |
    -service "service_list" [-eval]] [-node node_name | -instance instance_name |
    -serverpool pool_name] [-stopoption IMMEDIATE|TRANSACTIONAL|NONE] 
   [-drain_timeout timeout] [-wait {YES | NO}] [-force [-noreplay] 
   [-global_override] [-verbose]

Parameters

Note:

Starting with Oracle Grid Infrastructure 21c, policy-managed databases are deprecated.

Table A-101 srvctl stop service Command Parameters

Parameter Description
-node node_name

Optionally, you can specify the name of the node on which you want to stop services. Use this parameter without the –db parameter to stop all services on a specific node. If you use the –db parameter, then only the services on the specified node for that database are stopped.

-db db_unique_name

Specify a unique name for the database.
-pdb pluggable_database

Alternatively, use this parameter to stop services running on a specific pluggable database.
-service "service_list"

Specify a particular service or a comma-delimited list of service names enclosed in double quotation marks ("") you want to stop.

If you do not provide a service name list, then SRVCTL stops all services on the database or on a specific instance.
-pq

Specify this parameter to restrict the stop action to a parallel query service.
-instance instance_name

Optionally, you can specify the name of the instance for which you want to stop services.
-serverpool pool_name

Optionally, you can specify the name of the server pool that contains the service you want to stop.
—eval

Use this parameter to hypothetically evaluate the impact of the command on the system.
-stopoption IMMEDIATE|TRANSACTIONAL|NONE

Specify the method of stopping the service. If this attribute was previously set for the service, then that value is used as the default value if you do not include the -stopoption parameter in your command. Otherwise, the default is NONE.

  • IMMEDIATE permits sessions to drain before the service is stopped. Sessions that do not drain are terminated when the time limit specified by -drain_timeout is reached.
  • If you specify TRANSACTIONAL, then sessions are terminated as soon as they commit. The service is stopped when the time limit specified by -drain_timeout is reached and any remaining sessions are terminated.
  • If you specify NONE, then no sessions are terminated.

Note: You must use the -stopoption parameter with the -force parameter.
-drain_timeout timeout

Specify the time, in seconds, allowed for resource draining to be completed. Accepted values are an empty string (""), 0, or any positive integer. The default value is an empty string, which means that this parameter is not set. If it is set to 0, then draining occurs, immediately.

The draining period is intended for planned maintenance operations. During the draining period, all current client requests are processed, but new requests are not accepted. When set on the service this value is used when the command line value is not set.
-wait {YES | NO}

Choose YES to wait until service draining is completed on the node to stop the service.

-force [-noreplay]

Force SRVCTL to stop the service; this causes SRVCTL to disconnect all of the sessions using the stop option you specify (IMMEDIATE or TRANSACTIONAL), requiring the sessions using the service to reconnect and then connect to another instance.

Notes:

  • If you do not specify the -force parameter, then sessions already connected to this service stay connected, but new sessions cannot be established to the service.

  • Optionally, you can specify the -noreplay parameter if you do not want Application Continuity to replay in-flight transactions after a session is terminated.

    The -noreplay parameter is not limited to use with -force. However, if you do not want to replay in-flight transactions after you force the service to stop, then -force requires -noreplay.

-global_override

Override value to operate on a global service. SRVCTL ignores this parameter if the service is not a global service.
-verbose

Use this parameter to display verbose output.

Examples

The following example command stops services running on the crmeast PDB in the crm database using the IMMEDIATE method, allowing 60 seconds for services to transfer to another node: 

$ srvctl stop service -db crm -pdb crmeast -drain_timeout 60 -force 
- stopoption immediate -verbose

The following example command stops all services running on the node node1 that are managed by Oracle Clusterware using the default stop option specified for each service and waiting until all sessions have drained from that node. 

$ srvctl stop service -node node1 -wait yes

srvctl disable volume
Disables Oracle Clusterware management for a specific volume or all volumes.

This command allows a volume device to be stopped by operating on the Oracle Clusterware resource for the volume. This command does not stop volume device.

Syntax

srvctl disable volume {-volume volume_name -diskgroup disk_group_name |
    -device volume_device}

Parameters

Table A-117 srvctl disable volume Command Parameters

Parameter Description
-volume volume_name

Specify the name of the volume that you want to disable.
-diskgroup disk_group_name

Specify the name of the disk group in which the volume that you want to disable resides.
-device volume_device

Alternative to using the –diskgroup parameter, you can specify the path to the volume device that you want to disable.

Usage Notes

  • You can only use this command with Oracle Clusterware.

  • You must specify a particular volume that you want to disable. You can specify a volume that resides in either a particular disk group or on a particular volume device.

Example

The following example disables a volume named VOLUME1 that resides in a disk group named DATA: 

$ srvctl disable volume -volume VOLUME1 -diskgroup DATA

Parent topic: volume Commands

srvctl enable volume
Enables Oracle Clusterware management for a specific volume or all volumes.

This command allows a volume device to be started by operating on the Oracle Clusterware resource for the volume. This command does not start the volume device, and is different from the SQL command ALTER DISKGROUP ENABLE VOLUME or the ASMCMD command volenable, because these two commands bring the volume device online, in a running state, making the volume device accessible.

Syntax

srvctl enable volume {-volume volume_name -diskgroup disk_group_name |
   -device volume_device}

Parameters

Table A-118 srvctl enable volume Command Parameters

Parameter Description
-volume volume_name

Specify the name of the volume that you want to enable.
-diskgroup disk_group_name

Specify the name of the disk group in which the volume that you want to enable resides.
-device volume_device

Alternative to using the –diskgroup parameter, you can specify the path to the volume device that you want to enable.

Usage Notes

  • You can only use this command with Oracle Clusterware.

  • You must specify a particular volume that you want to enable. You can specify a volume that resides in either a particular disk group or on a particular volume device.

Example

The following example enables a volume named VOLUME1 that resides in a disk group named DATA: 

$ srvctl enable volume -volume VOLUME1 -diskgroup DATA

Parent topic: volume Commands

srvctl remove volume
Removes a specific volume.

Syntax

Use this command with one of the following syntax models:

srvctl remove volume -volume volume_name -diskgroup disk_group_name [-force]

srvctl remove volume -device volume_device [-force]

Parameters

Table A-119 srvctl remove volume Command Parameters

Parameter Description
-volume volume_name

Specify the name of the volume that you want to remove.
-diskgroup disk_group_name

Specify the name of the disk group in which the volume that you want to remove resides.
-device volume_device

Specify the path to the file system resource in which the volume that you want to remove resides.
–force

You can use this parameter to remove the volume even if it is running.

Usage Notes

  • You can only use this command with Oracle Clusterware.

  • The volume gets created when you create volumes in Oracle ASM.

  • You must specify a particular volume that you want to remove. You can specify a volume that resides in either a particular disk group or on a particular volume device.

Example

The following example removes a volume named VOLUME1 that resides in a disk group named DATA: 

$ srvctl remove volume -volume VOLUME1 -diskgroup DATA
srvctl start volume
Starts a specific, enabled volume.

Syntax

srvctl start volume {-volume volume_name -diskgroup disk_group_name |
    -device volume_device} [-node node_list]

Parameters

Table A-120 srvctl start volume Command Parameters

Parameter Description
-volume volume_name

Specify the name of the volume that you want to start.
-diskgroup disk_group_name

Specify the name of the disk group in which the volume that you want to start resides.
-device volume_device

Alternative to using the –diskgroup parameter, you can specify the path to the volume device that you want to start.

-node node_list

Optionally, you can specify a comma-delimited list of node names enclosed in double quotation marks ("") where volumes that you want to start reside.

Usage Notes

  • You can only use this command with Oracle Clusterware.

  • The srvctl start volume command does not create a volume service. Provided that the volume already exists and the volume resource is enabled, SRVCTL attempts to start it. If the volume exists but the resource is disabled, then srvctl start volume returns an error.

Example

The following example starts a volume named VOLUME1 that resides in a disk group named DATA: 

$ srvctl start volume -volume VOLUME1 -diskgroup DATA

Parent topic: volume Commands

srvctl status volume
Displays the status of a specific volume or all volumes.

Syntax

srvctl status volume [-device volume_device] [-volume volume_name] 
   [-diskgroup disk_group_name] [-node "node_list"]

Parameters

Table A-121 srvctl status volume Command Parameters

Parameter Description
-device volume_device

Optionally, you can specify the path to the volume device for which you want to display the status.
-volume volume_name

Optionally, you can specify the name of the volume for which you want to view the status.
-diskgroup disk_group_name

Optionally, you can specify the name of the disk group in which the volume resides for which you want to display the status.
-node "node_list"

Optionally, you can specify a comma-delimited list of node names enclosed in double quotation marks ("") where volumes for which you want to view the status reside.

Usage Notes

  • You can only use this command with Oracle Clusterware.

  • If you do not specify any of the optional parameters, then SRVCTL displays the status for all volumes.

  • If you specify only the -volume parameter, then SRVCTL displays the status for the volume that you specify.

  • If you specify only the -diskgroup parameter, then SRVCTL displays the status for the volumes that reside in the disk group that you specify.

  • If you specify only the -device parameter, then SRVCTL displays the status for the volume device that you specify.

  • If you specify the -diskgroup and -device parameters, then SRVCTL displays the status for the volume device in the disk group that you specify.

  • If you specify the -node parameter, then SRVCTL displays the status of the volumes that reside on the nodes you list.

Examples

This command displays information similar to the following:

$ srvctl status volume –volume vol1
Volume vol1 of diskgroup diskgrp1 for device volume_device_path1 is enabled
Volume vol1 of diskgroup diskgrp1 for device volume_device_path1 is running

In the preceding example, SRVCTL performs a status query on all nodes because the -node parameter is not specified. 

$ srvctl status volume
Volume vol1 of diskgroup diskgrp for device volume_device_path1 is enabled
Volume vol1 of diskgroup diskgrp for device volume_device_path1 is running
Volume vol2 of diskgroup diskgrp for device volume_device_path2 is enabled
Volume vol2 of diskgroup diskgrp for device volume_device_path2 is running

In the preceding example, SRVCTL displays the status of all registered volumes because the no parameter is specified.
