Part 2 Part 2 Problem symptoms and their resolutions This part of the book is intended for system programmers and administrators who are working with WebSphere Application Server for z/OS V6 and who must identify problems, analyze them, and fix them efficiently so that they can deliver good support for the WebSphere environment. Another objective of this part is to assist IBM support and technical professionals and Java developers who work in this environment. If a WebSphere for z/OS problem occurs, the symptom chapters can help you to determine what happened and why it happened. We show you how to diagnose various problem symptoms that are encountered in a WebSphere for z/OS environment. Flow charts guide you through each step of the analysis process. Based on tasks that you must perform and answers that you give to a series of questions that were designed to filter out irrelevant facts, we try to help you: Determine the problem area. Identify the type, source, and cause of the problem. Discover a solution. We also mention analysis tools and information sources that are related to the symptoms. When no feasible solution is apparent, you are directed to prepare documentation and contact IBM. © Copyright IBM Corp. 2002, 2005, 2006. All rights reserved. 39
