You can use problem determination to understand why your application,
or server, is not working.
Why and when to perform this task
Diagnosing problems can aid you in understanding why your enterprise
application or server is not working and 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 documentation.
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, see the Messages section of the WebSphere Process Server documentation.
- 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 documentation table
of contents and select Diagnosing problems 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 documentation table
of contents 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 documentation table
of contents 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 available 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 1.4.2 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.
- For current information available from IBM Support on known problems
with WebSphere Process Server and
their resolutions, see the WebSphere Process Server support page.
