Creating the Oracle9i User and Group

Create a local group and local user for Oracle on each node. For example, create the dba group and the oracle user. Make sure to assign the same user ID, group ID, and home directory for the user on each node. Refer to the examples below:

1. On each node running Oracle9i, enter:
     # groupadd -g 99 dba
     # useradd -g dba -u 999 -d /oracle oracle

   Set up your environment variables as described in the Oracle Real Application Clusters Installation and Configuration Guide. Refer to this guide for more information on the dba group and oracle user.

2. Create a password for the oracle user on each node:
     # passwd oracle
3. Make sure that the user oracle can remsh between the nodes without having to use or confirm a password. If not, in the oracle user account directory (for example, /oracle), create a .rhosts file that includes plus characters ("+ +") in the first line.
