Maintaining high availability when implementing WebSphere MQ clusters in a clustered WebSphere Application Server environment.

Both WebSphere Application Server clusters and WebSphere MQ clusters are widely used to provide high availability and balance workloads across an enterprise. Combining these technologies helps
you scale both your WebSphere Application Server and WebSphere MQ infrastructures, and enables WebSphere Application Server applications to use the faster bindings mode to retrieve messages from WebSphere MQ queues. However, without careful planning, the combination of WebSphere Application Server clusters and WebSphere MQ clusters can actually cause reduced overall availability, message build-up on queues, and stranded messages that must be processed manually. You can avoid these problems by using the options in this article for integrating WebSphere Application Server and WebSphere MQ clusters.
