Note: If you would prefer to browse PDF versions of this documentation using your Adobe Reader , see the Troubleshooting PDF files available from www.ibm.com/software/webservers/appserv/infocenter.html .

As an activity, troubleshooting or problem determination encompasses a wide range of tasks that might need to be performed at any phase in product usage. In addition to built-in preventative measures, the product provides a variety of tools to make problem determination easier.

The troubleshooting section of the documentation helps you understand why your enterprise application, appserver, or product installation is not working, and helps you resolve the problem.

There are several ways to find information for diagnosing and resolving problems:

For tips on investigating common problems, organized by task, see Troubleshooting by task: What are you trying to do?.

To look up the explanation and recommended response for a particular WebSphere Application Server error message, see the message reference.

For help finding product error and warning messages, interpreting messages, and configuring product log files, see Working with message logs.

Difficult problems might require the use of product tracing, which exposes the low-level flow of control and interactions among product components. For help understanding and using product traces, see Working with trace.

For help adding log and trace capability to your own application, see Adding logging and tracing to your application.

For help using product utilities to diagnose the problem, see Working with troubleshooting tools.

To find out how to look up documented problems, common mistakes, product prerequisites, and other problem-determination information on the IBM WebSphere Application Server public web site, or to obtain technical support, see Obtaining help from IBM.
