Replica mastership
When you create a new replica, its replica object (the database object that records the replica’s existence) is mastered by the creating replica. Therefore, you can modify or delete the replica object only at the creating replica, unless you transfer mastership to another replica.
To facilitate replica maintenance, make each replica self-mastering, which means that it masters its own replica object. For more information, see Transferring mastership of a replica object.
Note: To perform certain procedures on a replica object, you must make the
replica self-mastering. This requirement is noted in the documentation for
those procedures.
