5.2.7 Example of Using Role-Allocated Groups and Users

You can use role-allocated groups and users that is compliant with an Optimal Flexible Architecture (OFA) deployment.

Assumptions:

  • The user installing the Oracle Grid Infrastructure software is named RACDOMAIN\grid. This user was created before starting the installation.

    The option to use the Windows Built-in Account was selected for the Oracle Home user for Oracle Grid Infrastructure.

  • The name of the home directory for the Oracle Grid Infrastructure installation is OraGrid19c.

  • The user installing the Oracle RAC software is named oracle. This user was created before starting the installation.

    During installation of Oracle RAC, an Oracle Home user named RACDOMAIN\oradba1 is specified. The oradba1 user is a Windows domain user that was created before the installation was started.

    The name of the Oracle home for the Oracle RAC installation is OraRAC19c_home1.

  • You have a second, Oracle Database installation (not Oracle RAC) on this server. The installation was performed by the oracle user. The Oracle Home user is oradba2, and this user was not created before starting the installation.

    The Oracle Home name is OraDB19c_home1.

  • Both the Oracle databases and Oracle Clusterware are configured to use Oracle ASM for data storage.

After installing the Oracle software, you have the following groups and users:

Operating System Group Name Type of Group Members

ORA_DBA

OSDBA group

oracle, RACDOMAIN\grid, and the Local System built-in Windows account

ORA_OraRAC19c_home1_DBA

OSDBA group for the Oracle RAC home directory

RACDOMAIN\oradba1

ORA_OraDB19c_home1_DBA

OSDBA group for the Oracle Database home directory

oradba2

ORA_OPER

OSOPER group

none

ORA_OraRAC19c_home1_OPER

OSOPER group for the Oracle RAC home directory

none

ORA_OraDB19c_home1_OPER

OSOPER group for the Oracle Database home directory

none

ORA_ASMADMIN

OSASM group

RACDOMAIN\grid and the Local System built-in Windows account, and the database service IDs

ORA_ASMOPER

OSOPER for ASM group

 none

ORA_ASMDBA

OSDBA for ASM group for Oracle ASM clients

RACDOMAIN\grid, oracle, the Local System built-in Windows account, and Oracle Home Users of database homes

ORA_RAC19c_home1_SYSBACKUP, ORA_RAC19c_home1_SYSDG, and ORA_RAC19c_home1_SYSKM

Specialized role groups that authorize users with the SYSBACKUP, SYSDG, and SYSKM system privileges.

none

ORA_DB19c_home1_SYSBACKUP, ORA_DB19c_home1_SYSDG, and ORA_DB19c_home1_SYSKM

Specialized role groups that authorize users with the SYSBACKUP, SYSDG, and SYSKM system privileges.

none

If there are no users listed for an operating system group, then that means the group has no members after installation.
