You posted that "screen" before, so yes, I see you're logged in as root ;-)

I mean: what is the user(name) you're trying to add?!

the question is not clear.

Is this correct:
In Linux you are logged in is as root?

Then you have issued the command:
useradd -u 502 -c "Oracle RDBMS Owner" -g oinstall -G dba,oper,asmdba

and then an error occurred?

What I believe Alex140181 has suggested is that the command needs more
such as:

useradd -u 502 -c "Oracle RDBMS Owner" -g oinstall -G dba,oper,asmdba new_ora_user

i.e. the 'new_ora_user' is the user identity that you require in Oracle (with those permissions)
