How this book can help you

The approach in this book is to start with the symptoms of the problem, and try to use these symptoms to classify it. For each class of problem, possible causes are suggested, together with techniques we can use to establish what the cause is.

It is always assumed that the problem has a simple cause to start with (for example, an application programming error). If, as a result of investigation, it becomes clear that the cause of the problem is not straightforward, you must consider possible causes that might be more difficult to determine (and solve). Having exhausted all other possibilities, consider the possibility that the cause of the problem might be in WebSphere MQ itself, in which case you would need to get help from IBM.
