Oracle Database Oracle Clusterware Installation Guide for HP-UX

Creating Groups and Users for Oracle Clusterware
3. Repeat this procedure on all of the other nodes in the cluster.
2.4.5 Creating the Oracle Clusterware User
You must create a software owner for Oracle Clusterware in the following
circumstances:
■ If an Oracle software owner user does not exist; for example, if this is the first
installation of Oracle software on the system
■ If an Oracle software owner user exists, but you want to use a different operating
system user, such as crs, with different group membership, to give separate
clusterware and database administrative privileges to those groups in a new
Oracle Clusterware and Oracle Database installation
In Oracle documentation, a user created to own only Oracle Clusterware software
installations is called the crs user. A user created to own either all Oracle
installations, or only Oracle database installations, is called the oracle user.
2.4.5.1 Determining if an Oracle Software Owner User Exists
To determine whether an Oracle software owner user named oracle or crs exists,
enter a command similar to the following (in this case, to determine if oracle exists):
# id oracle
If the user exists, then the output from this command is similar to the following:
uid=501(oracle) gid=501(oinstall) groups=502(dba),503(oper)
Determine whether you want to use the existing user, or create another user.
If you want to use the existing user, then ensure that the user's primary group is the
Oracle Inventory group (oinstall).
2.4.5.2 Creating or Modifying an Oracle Software Owner User for Oracle
Clusterware
If the Oracle software owner (oracle, crs) user does not exist, or if you require a
new Oracle software owner user, then create it. The following procedure uses crs as
the name of the Oracle software owner.
1. To create a user, enter a command similar to the following:
2-6 Oracle Clusterware Installation Guide
Note: If you intend to use multiple Oracle software owners for
different Oracle Database homes, then Oracle recommends that you
create a separate Oracle software owner for Oracle Clusterware, and
install Oracle Clusterware using the Oracle Clusterware software
owner.
If you want to create separate Oracle software owners (oracle, crs,
asm) to create separate users and separate operating system privileges
groups for different Oracle software installations, then note that each
of these users must have the oinstall group as their primary group,
and each user must share the same Oracle Central Inventory, to
prevent corruption of the Central Inventory. Refer to "Creating
Custom Configuration Groups and Users for Job Roles" on page 3-4.
