16.3. Cluster Failover in C++

To use the MRG 3 C++ client with a cluster that uses a Virtual IP, simply specify the Virtual IP address as the broker address. Fail-over is handled transparently by the cluster manager.

In a case where you have a cluster that does not use a Virtual IP address, specify multiple cluster node addresses in a single URL and specify the connection option reconnect to be true. For example:

qpid::messaging::Connection c("node1,node2,node3","{reconnect:true}");

Heartbeats are disabled by default. You can enable them by specifying a heartbeat interval (in seconds) for the connection via the heartbeat option. For example:

qpid::messaging::Connection c("node1,node2,node3","{reconnect:true,heartbeat:10}");
