You cannot prevent from an administrator to do what he/she wants.
Anything you can do, he/she can undo.

You already said you removed the group but it can be added.
You can also set SQLNET.AUTHENTICATION_SERVICES = (NONE) in sqlnet.ora but it can be reset back.

As I said, if you want to prevent access from an administrator, you can't.

I didnt understand how the
other OS admin user have their oracle users created before hand
in the format

create user "OPS$DOMAIN.NAME\USER" identified externally;

Only after this user is present in DB, they can login.

Dear Michel ,

I was not trying to spread my question here and there .

Actually i was just curious to know that how other user

can log in to his DB after login to OS as they would need to have

corresponding users in DB first .
