Diagnosing and fixing problems

Why and when to perform this task

The purpose of this section is to aid you in understanding why your enterprise application, application server, or WebSphere Application Server is not working and to help you resolve the problem. Unlike performance tuning which focuses on solving problems associated with slow processes and un-optimized performance, problem determination focuses on finding solutions to functional problems.

Steps for this task

  1. For tips on investigating common problems organized according to tasks within WebSphere Application server, see Troubleshooting by task.
  2. For tips on how to investigate common kinds of problems based on the component that is causing the problem, see Troubleshooting by component.
  3. For help in using WebSphere Application Server utilities to help you diagnose the problem, see Working with diagnostic tools and controls.
  4. For help in viewing diagnostic information like dumps, error logs and CTRACE information, see Viewing diagnostic information
  5. The IBM Developer Kit and Runtime Environment, Java 2 Technology Edition, Version 1.4.1 Diagnostics Guide describes debugging techniques and the diagnostic tools that are available to help you solve problems with Java. It also gives guidance on how to submit problems to IBM. You can find the guide at http://www.ibm.com/developerworks/java/jdk/diagnosis/ .
  6. For current information available from IBM Support on known problems and their resolution, see the IBM Support page.
  7. IBM Support has documents that can save you time gathering information needed to resolve this problem. Before opening a PMR, see the IBM Support page.
