How do you connect to a Multi-Instance Queue Manager using MQQueueConnectionFactory

Question

We have an application which needs to communicate with a Multi-Instance QueueManager. Both (instances) are running on the default port and have unique addresses.

serverA.internal.company.address
serverB.internal.company.address

We use the following code to establish the ConnectionFactory:

MQQueueConnectionFactory connectionFactory = new MQQueueConnectionFactory();
connectionFactory.setTransportType(1);
connectionFactory.setPort(1414);
connectionFactory.setChannel("CLIENTCONNECTION");
connectionFactory.setQueueManager("queue.manager.name.here");
connectionFactory.setHostName("serverA.internal.company.address");

How can we specify both addresses so that failover is achieved without writing our own retry logic?

I found someone with a very similar issue (http://www.mqseries.net/phpBB2/viewtopic.php?t=57240&sid=02cc89b38c7795d2571155e1e3866aa5) on mqseries.net but their solution does not seem like it is applicable. — Randyaa, Nov 15 '13 at 20:33
connectionFactory.setConnectionNameList(string) might do the trick. I'm going to investigate. — Randyaa, Nov 15 '13 at 20:46

using the following:

connectionFactory.setConnectionNameList("serverA.internal.company.address(1414),"
                                      + "serverB.internal.company.address(1414)")

instead of

connectionFactory.setHostName("serverA.internal.company.address");
connectionFactory.setPort(1414);

did the trick for us.
