Crash on HP-UX specific MustGather information

Setup
Please ensure the following settings are in place to generate a full core from a Application Server crash:
  • Ensure that ulimit -c is set unlimited.
  • Ensure that gdb (or wdb on HP-UX) is installed and setup on your system.
  • Ensure you have sufficient disk space on the machine.

Gather
  1. Downlaod the script 'hpjdk_mg.sh' and make the script executable using the command:

    chmod +x hpjdk_mg.sh

    Note: Please make sure to download hpjdk_mg.sh as a binary file to avoid complications.

  2. Run the above script, note that the hpjdk_mg.out file is generated in the same directory.

  3. Follow these steps to package the core and the loaded shared objects in memory:
    1. Enter the following command:

      $ /opt/langtools/bin/gdb <path to java executable> core.xxxx           Note: java should point to WAS_HOME/java. for e.g                       gdb /opt/IBM/WebSphere/AppServer/java/bin/<Architecture>/java  core.xxx
      where Architecture
      IA64N for 32-bit java
      PA_RISC2.0 for RISC systems
    2. Once inside gdb and gdb loads successfully, issue the packcore command to package the exe and the libraries:
      (gdb) packcore

      Note: Packcore command produces a compressed package that should contain:
      • The core file
      • The modules.tar file which will package the object modules loaded at that point of time
      • The progname.txt file.
      • wdb (or Wildebeest Debugger) is available free for download from

        HP WDB download - latest release
  4. Collect the following information:

    For all releases:
    • hpjdk_mg.out 
    • packcore.tar.Z
    • All hs_err_pid*.log files

    For V6.0 and V6.1 releases:
    Include all of the files from the following directory:

    install_root/profiles/profile_name/logs/server_name

    For V5.0 and V5.1 releases:
    Include all of the files from the following directory:

    install_root/logs/server_name

    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.
