Problem |
When trying to determine the cause of a JIT
failure on AIX®, use the attached script to start WebSphere® Application
Server. |
|
|
|
Solution |
In order to debug JIT failures, it is
necessary to run multiple tests and gather log files from each
test.
Verify that your Java™ 2 SDK meets the following
criteria:
- ca1.2.2-20011020 or later
- ca1.3.0-20010615 or later
- 1.3.1 All levels
- Copy the attached startJit.sh file to the directory
install_root/bin (for
example: /usr/WebSphere/AppServer/bin).
- Modify the startJit.sh file with the following changes:
Create the following directory: /usr/JitDebug or modify the script to reflect another location.
- Run the startJit.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.
