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.
