            The ALTER DATABASE system privilege allows a user to:
            
                - Perform a database upgrade
 
- Perform cost model calibration
 
- Load statistics
 
- Change transaction logs (also requires the SERVER OPERATOR
                        system privilege)
 
- Change ownership of the database (also requires the MANAGE
                        ANY MIRROR SERVER system privilege)

				ADMIN OPTION, or WITH ADMIN ONLY OPTION clause. If you do not specify a clause, the
