Yes, you can either use an AMQP 0-10 style URL: amqp:tcp:host1:5672,tcp:host2:5672 or you can use the reconnect-urls option to set a list of URLs to try on failover. That list is what the FailoverUpdates sets when it receives notification of a change in cluster membership. > What I mean is > > Connection connection("host1:5672,host2:5672"); > connection.setOption("reconnect", true); > try { > connection.open(); > std::auto_ptr<FailoverUpdates> updates(new > FailoverUpdates(connection)); > ... > > So when host1 is unavailable we will connect to the host2.
