Once a Replication Server is registered as data service, use the following to start Replication Server as a data service:
hareg -y repserver_name
This starts Replication Server if it is not already running, and also starts the fault monitor for Replication Server.
To shut down Replication Server, use:
hareg -n repserver_name
The fault monitor restarts or fails over this Replication Server if it is shut down or stopped (killed) any other way.
