When you stop replication in the Mirror Replication Agent:
The internal Log Reader and Log Transfer Interface components stop their normal replication processing.
Any open connections to the primary database are released, and the connection to the Replication Server is dropped.
The Mirror Replication Agent instance goes from Replicating state to Admin state.
Some administrative tasks require the Mirror Replication Agent instance to be in Admin state. In a functioning Mirror Activator system, you must stop replication in the Mirror Replication Agent to perform those tasks.
There are two ways to stop replication in the Mirror Replication Agent:
Quiesce the Mirror Replication Agent instance to stop replication gracefully. See “Quiescing the Mirror Replication Agent” for more information.
Suspend the Mirror Replication Agent instance to stop replication immediately. See “Suspending the Mirror Replication Agent” for more information.
