4. To determine whether the oracle user exists and belongs to the correct groups,
enter the following command:
# id oracle
If the oracle user exists, then this command displays information about the
groups to which the user belongs. The output should be similar to the following,
indicating that
oinstall is the primary group and dba is a secondary group:
uid=440(oracle) gid=200(oinstall) groups=201(dba),202(oper)
5. If necessary, complete one of the following actions:
■ If the oracle user exists, but its primary group is not oinstall or it is not a
member of the
dba group, then enter the following command:
# /usr/sbin/usermod -g oinstall -G dba oracle
■ If the oracle user does not exist, enter the following command to create it:
# /usr/sbin/useradd -g oinstall -G dba oracle
This command creates the oracle user and specifies oinstall as the primary
group and
dba as the secondary group.
6. Enter the following command to set the password of the oracle user:
# passwd oracle
