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 help in knowing where to find error and warning messages, interpreting messages, and configuring log files, see Working with message logs.
  3. 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.
