Creating an Oracle Software Owner User

Before starting installation, create Oracle software owner user accounts, and configure their environments.

Oracle software owner user accounts require resource settings and other environment configuration. To protect against accidents, Oracle recommends that you create one software installation owner account for each Oracle software program you install.

If the Oracle software owner user (oracle ) does not exist, or if you require a new Oracle software owner user, then create it as described in this section.

The following example shows how to create the user oracle with the user ID 54321; with the primary group oinstall; and with secondary group dba.

# /usr/sbin/useradd -u 54321 -g oinstall -G dba oracle

You must note the user ID number for installation users, because you need it during preinstallation.

For Oracle Grid Infrastructure Installations, user IDs and group IDs must be identical on all candidate nodes.
