This section describes High Availability (HA) for RTViewCentral, the setup options available and how to configure them. HA prevents the loss of data and alerts in the event of a failover.
To setup HA for RTViewCentral you configure a pair of RTViewCentral installations on two different host machines, one as the primary host and the other as the backup host. The HA configuration includes the CentralServer, Display Server and Historian. If one of these processes on the primary host stops, the corresponding process on the backup host takes over. When the primary comes back on line it takes over again and the backup process returns to standby mode. Client connections move between the two servers accordingly.
