To create Oracle user and groups on all nodes in the cluster

1. From the SF Oracle RAC installer menu, enter 1 to select the option Create Oracle User and Group.

   1)  Create Oracle User and Group
   2)  Create Storage for OCR and Voting disk
   3)  Oracle Network Configuration
   4)  Exit SF Oracle RAC Configuration
   b)  Back to previous menu

2. Provide the following information for creating the Oracle user and groups: user ID, group ID, user name, group name, and the full path of the Oracle user home directory.

   The user ID and group ID must not be in use on any node in the cluster. The installer suggests unused values, which you may use or change as required. The configuration program assigns the same values on all the nodes.

   Note:

   If you are configuring GCO, then the user IDs and group IDs of all nodes on both the primary and secondary clusters must be the same. While configuring the user ID and group ID values on the secondary site, make sure that they are identical to the values used at the primary site.

   Enter Oracle UNIX user name: [b] oracle
   Enter Oracle UNIX group name: [b] (oinstall)
   Enter Oracle user's ID (numerical):  [b] (1165) 1000
   Enter Oracle group's ID (numerical):  [b] (1165) 1000
   Enter absolute path of Oracle user's Home directory: [b] /home/oracle

   If the specified user name does not exist on any node in the cluster, the following prompt is displayed:

   User oracle does not exist on any node. Do you want to create it 
   with the information provided [y,n,q] (y)

   Enter y to create the Oracle user with the information provided.

   Note:

   The installer creates the Oracle user IDs and group IDs with the same value on each cluster node. If you are configuring GCO, then the user IDs and group IDs of all nodes on both the primary and secondary clusters are the same.

   If the installer encounters any of the following scenarios, you are prompted to manually modify the user ID and group ID information before you install Oracle Clusterware:

   • The Oracle user already exists with a different user ID or group ID on any node in the cluster.

   • The user ID and group ID exist with the same user ID and group ID on a subset of nodes.

   If the installer discovers that the user ID and group ID exist on all the nodes with the same user ID and group ID on all the nodes, it proceeds to the next step.

3. Enter the information for the secondary group.

   Do you want to create a secondary group 
   for Oracle user? [y,n,q,b,?] (n) y
   Enter Oracle UNIX group name:  [b] (dba, oper etc.) dba
   Enter Oracle group's ID (numerical): [b] (1996) 1001
   
       Creating secondary group dba for 
   				Oracle user oracle on galaxy ..... Done
       Creating secondary group dba for 
   				Oracle user oracle on nebula ..... Done
   Do you want to create another secondary group 
   for Oracle user? [y,n,q,b,?] (n)
