Problem(Abstract) |
When trying to determine the cause of a Just-In-Time (JIT)
failure on AIX®, use the attached script to start IBM® WebSphere®
Application Server. |

|
Resolving the
problem |
In order to debug JIT failures, it is necessary to run
multiple tests and gather log files from each test.
- Copy the attached startJit50.sh file to the directory,
install_root/bin
(for example: /usr/WebSphere/AppServer/bin)
- Modify the startJit50.sh file with the following changes:
- Determine what application server you are debugging and modify the
script. The script is set to debug server1.
- Create the following directory: /usr/JitDebug or modify the
script to output to another location.
- Run the startJit50.sh script, select an option and determine
if the crash still occurs.
- For each crash, run the kca command against the core file, and
provide the requested files, then continue with the next test. For more
information on kca, refer to MustGather:
Crash on AIX.
- If running an option does not produce a failure, stop and contact
support.
For each test, submit
the following diagnostic information to IBM Support:
- Standard data file format (SDFF) files.
- kca.out
- core-libs.tar.Z (this file is generated as a
result of executing step 4)
- Renamed core file.
- install_root/bin/runhistory
-
install_root/bin/start.jit.log
- All files from the directory, /usr/JitDebug (or
the alternative directory specified in step 2b).
