Use the synchronization service when multiple Data Mover servers are installed and automatic failover is not available or enabled. The synchronization service creates a backup system to use as a temporary active system in case of a daemon failover on the active system.
The dmsync commands used in this section apply to the standalone synchronization service, and are not used during automatic failover. Automatic failover makes use of the synchronization service using dmcluster commands from the automatic failover feature.
When using the synchronization service with multiple Data Mover servers, the following terminology applies:
Active server
The Data Mover server where the daemon is running.
Standby server
One or more Data Mover servers where the daemon is not running. Use standby servers as the primary system if a failure on the designated (or primary) active server occurs.
