Trouble with "oracle" user
I am trying to install Oracle Database 11g on Oracle Linux 6. The installation directions state that I should determine whether the oracle user exists, so I enter:
# id oracle
And I receive back the following:
uid=53135(oracle) gid=8500(dba) groups=8500(dba),100(users)
Next I am suppose to make oinstall the primary group for the oracle user and so I enter:
# /usr/sbin/usermod -g oinstall oracle
And I receive back the following:
usermod: user 'oracle' does not exist in /etc/passwd
Does the oracle user really exist? If so, how can I change the primary group? Also, what is the default password for oracle user?
