Installing Standard Edition High Availability Database Software on Local File System

You can install Oracle Database software binaries on a local file system to enable the Oracle Database Standard Edition high availability feature.

Ensure that all the cluster nodes, on which you plan to configure Standard Edition High Availability, have the same operating system configuration, database users, database groups, resource limits, and SSH equivalence for the Oracle Database software owner user (oracle).

Before you start the installation, have all the information you need about users, groups, and storage paths. You should also be prepared to run root scripts or provide information to automate root scripts.

  1. As the root user, log into the first cluster node on which you want to configure Standard Edition High Availability and create the Oracle base directory on the local file system. Follow the Oracle Optimal Flexible Architecture (OFA) recommendations and specify the correct owner, group, and permissions for this directory.
    # mkdir -p /u01/app/oracle
    # chown oracle:oinstall /u01/app/oracle
  2. Log in to the first cluster node as the Oracle Database software owner user (oracle).
  3. Download the Oracle Database 19c release 19.3 installation image file (db_home.zip) from Oracle Software Delivery Cloud website to a directory of your choice.
  4. Download the Oracle Database Release Update 19.7 or later patch from My Oracle Support to a directory of your choice and unzip it.
  5. Create an OFA-compliant Oracle home directory on the local file system and extract the image files that you have downloaded in to this Oracle home directory. For example:
    $ mkdir -p /u01/app/oracle/product/19.0.0/dbhome_1
    $ cd /u01/app/oracle/product/19.0.0/dbhome_1
    $ unzip -q /tmp/db_home.zip
  6. From the Oracle home directory, run the runInstaller command with the -applyRU flag to start the Oracle Database Setup Wizard and apply the Oracle Database Release Update 19.7 or later patch during installation.
    $ ./runInstaller -applyRU patch_directory_location/patch_ID
    

    Note:

    Run the runInstaller command from the Oracle home directory only. Do not use the runInstaller command that resides at $ORACLE_HOME/oui/bin/, or any other location, to install Oracle Database.
  7. In the Select Configuration Option screen, select Set Up Software Only.
  8. In the Select Database Installation Option screen, select Single instance database installation.
  9. In the Select Database Edition screen, select Standard Edition 2.
  10. Respond to the configuration prompts as needed.
  11. Provide information to automate root scripts, or run scripts as root when prompted by the setup wizard.

    If you configure automation for running root scripts, and a root script fails, then you can fix the problem manually, and click Retry to run the root script again.

    Note:

    Click Help if you have any questions about the information you are asked to submit during installation.
  12. Optional: As the oracle user, enable read-only Oracle home on the first cluster node.
    $ $ORACLE_HOME/bin/roohctl -enable
  13. As the root user, create the Oracle base directory on all of the other cluster nodes on which you want to configure Standard Edition High Availability.
    # mkdir -p /u01/app/oracle
    # chown oracle:oinstall /u01/app/oracle
  14. As the oracle user, run the addnode.sh script from the first node to perform the following operations on the other nodes on which you want to configure Standard Edition High Availability:
    • Copy the Oracle home directory from the first node to the other nodes.
    • Setup Oracle base and Oracle inventory directories on the other nodes.
    $ $ORACLE_HOME/addnode/addnode.sh -silent CLUSTER_NEW_NODES=comma_separated_list_of_other_nodes
  15. As the root user, run the root.sh script on all the other cluster nodes on which you are configuring Standard Edition High Availability.
    # /u01/app/oracle/product/19.0.0/dbhome_1/root.sh

After the Oracle Database software installation is complete, use Oracle Database Configuration Assistant (Oracle DBCA), in either interactive or silent mode, to create a Standard Edition database on the first cluster node on which you installed the Oracle Database software.

For more information about the requirements for creating a database, and the procedure for enabling and configuring Standard Edition High Availability for Oracle Databases, refer to Oracle Database Administrator’s Guide.
