Introduction to problem determination

 

This book tells you how to find the reasons for problems with WebSphere MQ for z/OS. Usually, you start with a symptom, or set of symptoms, and trace them back to their cause. This book describes tools and techniques we can use to find the cause of a problem and suggests actions for solving the problem.

The process of problem determination often enables you to solve a problem. For example:

• If you find that the cause of the problem is an error in an application program, we can solve the problem by fixing the error.

• If you find that the cause of the problem is an error in your system programming (such as an error in resource definition), we can solve the problem by correcting the error.

However, you might not always be able to solve a problem after determining its cause. For example:

• A performance problem might be caused by a limitation of your hardware.

• You might find that the cause of the problem is in WebSphere MQ for z/OS itself. If this happens, we need to contact your IBM support center for a solution.
