Super-users can exercise any system privilege and administer any role; they can perform any privileged operation in the system. Role-based security does not require a super-user to maintain the database; the DBA user might not be a super-user.
By default, the DBA user can exercise any system privilege, but since it might not be able to administer all user-defined roles, it is not considered a true super-user. SAP Sybase IQ does not automatically create a super-user for a new or migrated database.
To maintain the super-user status, once you have created a super-user, all new user-extended and user-defined roles must be granted to the super-user, with administrative rights.
To allow the DBA user to act as a super-user, all new user-extended and user-defined roles must be granted to the DBA user, with administrative rights.
Administrative rights can be granted in the form of a role administrator or a global role administrator.
