Recovery strategy

  • Manual--the primary machine will act as standby for the backup machine until you have manually forced the primary to takeover.
Heartbeat source address
The address of the high availability partner machine that sends heartbeats. This address should be defined on the physical adapter of the partner that you wish to use to monitor the health of the Dispatcher. You can define a source address for each physical adapter in the Dispatcher machine.

Heartbeat destination address
The destination address is the address of the high availability partner machine to which heartbeats and responses are sent. This address should be defined on the physical adapter of the partner that you wish to use to monitor the health of the Dispatcher. You can define a destination address for each physical adapter in the Dispatcher machine.
