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:
install_root/logs
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.
