Creating the Oracle user and groups manually

On each system, create a local group and local user for Oracle. Be sure to assign the same group ID, user ID, and home directory for the user on each system. The following procedure creates the group 'oinstall' (Oracle Inventory group) and the user 'oracle' (Oracle software owner user).

Note:

When you create the user and group, make sure that you specify a user and group ID that is not in use.

To create the operating system Oracle user and group on each system

  1. Create the 'oinstall' group on each system.

    # groupadd -g 1000 oinstall
    # groupadd -g 1001 dba
  2. Create the Oracle user and the user home directory on each system:

    # useradd -g oinstall -u 1000 \
    -G dba -m -d /home/oracle oracle
