How to use this book

Use this book when we need assistance in resolving problems associated with using of WebSphere MQ for z/OS.

"z/OS" means any release of z/OS that supports the current version of WebSphere MQ.

This book will help you decide whether the problem is caused by the way your system is set up, an application programming error, or a fault with the WebSphere MQ for z/OS program itself. The book guides you through problem analysis techniques.

Sometimes, you might mistake a failure within another environment, such as CICS or TSO, for a failure in WebSphere MQ for z/OS. Wherever possible, this book helps you isolate WebSphere MQ for z/OS problems, and refers you to the appropriate publications if the error appears to be in another product.

If you decide that the problem is with the WebSphere MQ for z/OS code itself, this book tells you how to develop a set of keywords to use as a search argument in the IBM software support database, and how to communicate effectively with the IBM support center.
