Crash on AIX specific MustGather information
For a WebSphere Application Server crash on the AIX platform, a core file is produced. This file is located in the install_root/bin directory or the operating_system_root/tmp directory.
If a core file is not found, see MustGather: Crash on AIX produces no core or truncated core.
Otherwise, perform the following steps:
- Rename the core file so that it is not overwritten by another failure of programs or tools.
- Enter the following command:
| errpt -a > errpt.out |
 |
- Enter the following command:
| ./dbxtrace_aix.sh [executable] [core_file_name] >dbxtrace.out |
 |
Where:
| [executable] |
is usr/WebSphere/AppServer/java/jre/bin/java |
| [core_file_name] |
is the core file |
| dbxtrace.out |
is changed for each core file |
|
|
- Enter the following command:
| kca -j[N] [core_file_name] -d > kca.out |
 |
Where:
| -j[N] |
Specifies the version of Java™ that was used by the process that generated the core file as follows |
| -j2 |
is Java 1.2.2 (WebSphere Application Server V3.5) |
| -j3 |
is Java 1.3.0 (WebSphere Application Server V4.0.1 and 4.0.2) |
| -j4 |
is Java 1.3.1 (WebSphere Application Server V4.0.3+ and V5.0) |
| -j5 |
is Java 1.4.X (WebSphere Application Server V5.1 and higher) |
|
|
- Enter the following command:
| ./getlib.sh java_executable_fullpath core_filename |
|
| Note: Creates getlib_archive.tar.Z. Must have dbx installed to run this command. |
|
- Enter the following command:
| tar cvf core_file_name.tar core_file_name |
|
| Note: Creates core_file_name.tar. |
|
- Enter the following command:
| ./jextract -o core.sdff [CORE_PATH] |
|
Where:
jextract |
is found in the install_root/java/jre/bin directory |
core.sdff |
is the output file |
[CORE_PATH] |
is the path and file name for the core file |
|
|
- Send the following files to IBM Support:
- All javacore.txt files
- All dbxtrace.out files
- All standard data file format (SDFF) files
- errpt.out
- All kca.out files
- All getlib_archive.tar.Z files
- All core.tar files
- For releases of V6.0:
- All files in the following directory:
| install_root/profiles/profile_name/logs/server_name |
|
- A copy of server.xml located in the following directory:
install_root/profiles/profile_name/config/cells/
cell_name/nodes/node_name/servers/server_name |
|
- For releases of V5.0 and V5.1:
- Include all of the files from the following directory:
| install_root\logs\server_name |
|
- A copy of server.xml located at the following directory:
install_root/config/cells/cell_name/nodes/
node_name/servers/server_name |
|
- For releases of V3.5 and V4.0:
- Include all of the files from the following directory:
- A copy of XMLExport for the server configuration
|
| Note: For all versions, if you have configured the application server to write logs into a different location, send them accordingly. |
|
- Follow instructions to send diagnostic information to IBM support.
Notes:
- See the attached scripts dbxtrace_aix.sh and getlib.sh. kca is attached in compressed file kca_108_aix32.tar.gz.
- To run the dbxtrace_aix.sh file or getlib.sh, you must have the dbx component of AIX installed on the machine.
