I came across The Support Authority series of WAS related articles on developerWorks the other day, with their latest article on WAS trace released yesterday.

In this series a group of IBM’s technical support professionals are taking the time to explain the trace, and other RAS (reliability, availability and serviceability) features, of WebSphere Application Server and IBM’s JVM.

If you use WMQ as a messaging provider for WAS, or standalone WMQ JMS applications, I suggest taking a look.
