You can use problem determination to understand why your application,
or server is not working.
Why and when to perform this task
The following topic can aid you in understanding why your enterprise
application or server is not working, and they can help you resolve problems.
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. For more information about diagnosing
problems, see the
Diagnosing problems (using diagnosis tools) section
in the
WebSphere Application Server Network Deployment,
Version 6.0, information center.
Steps for this task
- Investigate common problems organized according to functional areas
within IBM® WebSphere® Process
Server in Troubleshooting
by function.
- If you already have an error message and want to quickly look up
its explanation and recommended response, look up the message by selecting Reference in
the information center navigation and expanding Messages.
- For help in knowing where to find error and warning messages, interpreting
messages, and configuring log files, expand the Diagnosing problems
(using diagnosis tools) section in the WebSphere Application Server Network Deployment,
Version 6.0, information center navigation and select Working with message
logs.
- Difficult problems can require the use of tracing, which exposes
the low-level flow of control and interactions between components. For help
in understanding and using traces, expand the Diagnosing problems
(using diagnosis tools) section in the WebSphere Application Server Network Deployment,
Version 6.0, information center navigation and select Working with trace.
- For help in adding log and trace capability to your own application,
see Adding logging
and tracing to your application.
- For help in using settings or tools to help you diagnose the problem,
expand Diagnosing problems (using diagnosis tools) section
in the WebSphere Application Server Network Deployment,
Version 6.0, information center navigation and select Working with troubleshooting
tools. Some of these tools are bundled with the product, and others
are downloadable.
- To find out how to look up documented problems, common mistakes,
WebSphere Process Server prerequisites, and other problem-determination information
on the WebSphere Process Server public Web site, or to obtain technical support
from IBM, see Obtaining
help from IBM.
- 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 IBM developer kits: Diagnosis documentation Web site.

and their resolution, see the IBM Support page.
- IBM Support has documents that can save you time gathering information
needed to resolve this problem. Before opening a PMR, see the WebSphere
Process Server support page.
