Heartbeat source addressEnter an intial heartbeat source address in either dotted decimal or host name format. The source address is 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. NOTE: For the mutual high availability feature (role of the dispatcher machine is both primary and backup), you need to specify the NFA (nonforwarding address) of the machine as the main heartbeat. Additional heartbeats can specify other network addresses of the machines. Heartbeat destination addressEnter an intial heartbeat destination address in either dotted decimal or host name format. 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. NOTE: For the mutual high availability feature (role of the dispatcher machine is both primary and backup), you need to specify the NFA (nonforwarding address) of the machine as the main heartbeat. Additional heartbeats can specify other network addresses of the machines. |
