Use this overview task to help resolve a problem that you
think is related to service integration technologies.
About this task
If you encounter a problem that you think might be related
to service integration technologies, complete the following stages.
Procedure
- Check the "Tips for troubleshooting" related links
for specific problems related to service integration technologies.
- Use Troubleshooting service integration message problems to
investigate problems with messages, such as messages not arriving
or being consumed. If the tips and the investigations do
not help you fix the problem, complete the following general stages.
- Check the Release Notes® for known problems and their resolution.
The Release Notes are
available from the WebSphere Application
Server library web site.
- For current information from IBM® Support on known problems and their resolution,
see the WebSphere Application
Server support page.
- Search the WebSphere Technotes
database.
You can use the following queries to
find articles for service integration technologies:
- Check for error messages.
Check
in the application server SystemOut log at profile_root\logs\server_name\SystemOut.log for
error messages, where profile_root is the directory
in which profile-specific information is stored.
Check in the SYSPRINT or SYSOUT log for error messages.

The Troubleshooter reference: Messages contains
information about the messages, indexed by message prefix. For each
message there is an explanation of the problem, and details of any
action that you can take to resolve the problem.
- Check for more information and error messages that might
provide a clue to a related problem. For example, if you
see WebSphere MQ error
messages or reason codes in WebSphere Application
Server messages and logs, refer to the WebSphere MQ Messages document at http://publibfi.boulder.ibm.com/epubs/pdf/amqzao05.pdf.
- If the information obtained in the preceding stages is
still inconclusive you should explore further, for example by enabling
the application server debug trace to provide a detailed exception
dump.
