[oracle] Granting DBA privileges to user in Oracle

How do I grant a user DBA rights in Oracle? I guess something like:

CREATE USER NewDBA
IDENTIFIED BY passwd;

GRANT DBA TO NewDBA WITH ADMIN OPTION;

Is it the right way, or...

This question is related to oracle oracle11g

The answer is


You need only to write:

GRANT DBA TO NewDBA;

Because this already makes the user a DB Administrator
