Today sees the release of WebSphere MQ SupportPac MR01. This provides the source for a WebSphere MQ channel exit which can be configured with a list of host names and port numbers to which the channel will attempt to connect. The intention is that this exit can be used when using a WebSphere MQ link to connect a clustered Service Integration Bus messaging engine to a queue manager. The messaging engine can now failover to another cluster member and the queue manager will still be able to connect.
