Terminates database replication operations.
1 – Description
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.

3 – Parameters
3.1 – database-rootfile
Specifies the database root file for which you want to stop replication operations.
4 – Command Qualifiers
4.1 – Abort
Abort=Forcex Abort=Delprc Noabort Indicates whether pending after-image journal information is rolled forward on the standby database before database replication operations are shut down. The following list describes the qualifiers: o Abort=Delprc The Abort=Delprc qualifier closes the database, and recovery unit journals (RUJ) are not recovered. The processes and any subprocesses of all Oracle Rdb database users are deleted. o Abort=Forcex The Abort=Forcex option closes the database, and recovery unit journals (RUJ) are recovered and removed. o Abort When the Abort qualifier is specified without a keyword, database replication shuts down as quickly as possible. Any after-image journal information waiting to be rolled forward on the standby database is discarded, and all active transactions on the standby database are rolled back. o Noabort (default) Database replication shuts down after all after-image journal information waiting to be rolled forward on the standby database is completed. Note that this type of shutdown could still result in active transactions being rolled back on the standby database.
4.2 – Log
Log Nolog Enables or disables logging the results of the Replicate After_ Journal Stop operation. Applicable to: Master and standby databases Required or Optional: Optional Default Value: Nolog If you specify the Log qualifier, the log file output is written to SYS$OUTPUT on OpenVMS.
4.3 – Wait
Wait Nowait Indicates whether or not the Replicate command should wait for activation of the replication server processes before returning control to the user. Applicable to: Master and standby databases Required or Optional: Optional Default Value: Wait The Wait qualifier has the following effects: o On the master database node-replication waits for deactivation of the server processes on the master database node o On the standby database node-replication waits for deactivation of the server processes on the standby database node The following list describes the Wait and Nowait qualifiers: o Wait (default) The Replicate command does not return to the user until the respective server process has successfully stopped the database replication operation. Replication waits indefinitely for the termination of the server process, even though termination might take substantial time. However, the server process might not actually stop the replication operation. o Nowait Control should be returned to the user as soon as the LCS or LRS server process has been stopped by the database monitor. NOTE You must wait for commands that include the Nowait qualifier to complete before you enter another command. This is because if the first command fails before the subsequent command executes, the second command might receive the HOTCMDPEND error. For example: $ RMU/REPLICATE AFTER_JOURNAL START/NOWAIT mf_personnel $ RMU/REPLICATE AFTER_JOURNAL STOP/WAIT mf_personnel If the first command to start replication fails, the startup error might be returned to the waiting Replicate After_ Journal Stop command.
