Gurus, i am new to Websphere MQ. I am settingup a MQ cluster and would like to configure websphere application server for JMS application which does put and read messages from these cluster queue's. Can anybody guide me on this, may be some reference links ? I really appreciate your help on this.

What you want are the Cluster & Using Java manuals, or their online equivalents in the info centre. Also cast you eyes across this forum's JMS & Cluster sections for a number of useful discussions that will help prevent you repeating the mistakes of others!

Put simply (and my Java is not production strength) there is no real difference between an app running in a clustered environment and one running on a stand alone queue manager. Your app must make a connection to a queue manager and use that to do what it must. If the queue manager is clustered that affects the role of the MQ administrator not the programmer.

I'll highlight one popular misconception just to prevent an obvious gotcha. Even in a clustered envirnment you can only read from the local copy of a clustered queue. It's a popular misconception that all queues in a cluster are available to all reading applications. Reasons for this are laid out most clearly in the documentation.

Happy Reading
