DBM Operators: Creating, Editing and Deleting 
DBM operators manage databases. They can log on to the database in any operational state.
Note that DBM operators are not database users. They can neither change data in the database nor log on to query tools or the Loader.
Prerequisites
You are logged on to the database as a database system administrator or DBM operator with server authorization for managing DBM operators.
