Chapter 3 Redundancy & Fault Tolerance : Failover

Failover
Client reconnection during failover is automatic. No explicit action is required by programmers. Rendezvous clients automatically reconnect to the same IP address, and cannot distinguish whether they are connected to the primary or the backup.
Failover preserves inbox names (because they are keyed to the IP address). Clients continue to receive point-to-point messages at the same inbox names.
The failover sequence appears to a client application as a transient TCP disconnect:
1.
2.
Since the primary is unavailable, the client transport automatically connects to the backup—though the client cannot detect this difference. (For further details of this process, see Activity Switches Between Redundancy Pairs in TIBCO Messaging Appliance P-7500 Operations Guide.)
3.
When reconnected, the client transport presents an RVD.CONNECTED advisory, and messages continue to flow as before.
