You can enter the command on either the master node or the
standby node.
When you enter the command on the master database, replication
is terminated immediately. Active transactions are handled
differently depending on whether you specify the Abort qualifier
or take the default (Noabort).
When you enter the command on the standby database, replication
is terminated after any pending after-image journal records are
completely rolled forward. Any active transactions on the standby
database are rolled back.
You can stop database replication while the master database,
the standby database, or both databases are on line (open) and
accessible for active use. There is no need to close either
database to stop database replication.
If the database is not manually opened on the node where you
entered the Replicate After_Journal Start command, you must enter
the Replicate After_Journal Stop command on the node where the
corresponding replication server is running, or first open the
database manually.
When replication operations stop, the Hot Standby software
automatically restarts the AIJ log server (ALS) processes on
the standby node.
