Which three will be true after a switchover to Dogs?
A.
Sheep will be an enabled logical standby database.
B.
Cats will be an enabled physical standby database.
C.
Dogs will be the primary database.
D.
Sheep will be a disabled logical standby database.
E.
Cats will be a disabled physical standby database.
Correct Ans: A, B, C
If the switchover transitions a physical standby database to the primary role, then:
The original primary database will be switched to a physical standby role.
Bystander standbys will receive redo from the new primary database.
The original primary database will be restarted as a part of the switchover operation. Note that the new primary database does not need to be restarted.
Standby databases not involved in the switchover (known as bystander standby databases) continue operating in the state they were in before the switchover occurred and will automatically begin applying redo data received from the new primary database.
