Creating Oracle user and group id

You must create the groups oinstall (the Oracle Inventory group) and dba, and the user oracle, assigning the primary group for oracle to be oinstall and the secondary group for oracle to be dba. Refer to Oracle Real Application Clusters Installation and Configuration Guide for more information.

You can create Oracle users and groups using the SF Oracle RAC configuration program. To create different groups, you must launch the configuration program and perform the procedure again.

 To create an Oracle user and group id on all nodes

1. Select Create Oracle user and group id if you want to specifically perform this task.
2. Provide the required information.

   The configuration program assigns the same values on all nodes. The text within parentheses is the default, which you may select by pressing Enter.

   Enter Oracle UNIX user name: (oracle)

   Enter Oracle UNIX user id: 100

   Enter Oracle UNIX user home dir: /home/oracle

   Enter Oracle UNIX group name: (oinstall)

   Enter Oracle UNIX group id: 1000

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

3. Create secondary groups for Oracle user as required.
4. Create a password for the oracle user on each node.

   # passwd oracle

5. Review as the configuration program verifies the ssh or remsh permission for Oracle user on all the nodes.

   Oracle installation requires ssh or remsh permission to be set for the Oracle user.

6. If the ssh or remsh verification fails on any nodes, enable ssh or remsh access in those nodes.
