Robin, I'm assuming you mean JMS MQ Client?
You don't need to do anything special to connect to a MQ Manager in a cluster. If the MQ Manager you've put a message to fails before the message has been removed by the receiving application, it will be unavailable until the MQM comes back up. You can not achieve load balancing with your JMS MQ Client because it connects to only one MQM at a time. You'd have to create a third MQM, a hub, to receive messages from the JMS MQ Client and then do a round-robin or load-balancing distribution to your two existing MQMs. Your hub MQM could be on the same box as your Client and therefore not add an additional single point of failure (from a hardware perspective).

We need to configure it to send and receive messages from a MQ Cluster. We have 2 MQ Queue managers running on physically different boxes which hav been clustered. Is there any special configuration on JMS (WebSpher App Server) to target a clustered queue ? I am wondering if I explicitly put a message on queue on machine 1 , what will happen if the queue manager on machine1 goes down. Will it be available since it is a MQ Cluster ? We are basically looking out for Mq clustering to offer load balancing & Failover. Any help in this will be appreciated -- Thanks & Regards, Robin Instructions for managing your mailing list subscription are provided in the Listserv General Users Guide available at http://www.lsoft.com Archive: http://vm.akh-wien.ac.at/MQSeries.archive
