Monitoring Replication Servers 
The enqueue replication server is normally monitored by an extra software program. This may be the SAP start service, which starts the replication instance, or it may be HA software, which monitors the enqueue and replication servers in the cluster.
Several return codes are implemented to provide monitoring software with information about the cause of any replication server shutdowns.
Procedure
You should configure the monitoring software of the replication server so that it can respond to the different return codes if the server does shut down.
