Crash on Microsoft Windows specific MustGather information
The following steps outline where to collect information and begin
troubleshooting a Java™ virtual machine (JVM) crash on a Windows platform:
- Collect Drwtson32.log and user.dmp files. To
determine what the "Log File Path" (location of drwtsn32.log) and
"Crash Dump" (location of user.dmp) paths are set to, run
drwtsn32 from a command line.
- Default location for Microsoft Windows 2000:
\Documents and Settings\All
Users\Documents\DrWatson |
 |
- Collect javacore*.txt files located in the JVM working
directory.
- For the Application Server, Nanny and Administrative
Server, the following is the default working directory on the Windows
platform:
\Winnt\System32 |
 |
- The Application Server working directory is specified in
the Administrative Console in AppServer/General tab for V4.0.
- Collect the following information:
- For V6.0 release:
- 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 V5.0 and V5.1 releases:
- Include all of the files from the following directory:
install_root\logs\server_name |
 |
- A copy of server.xml located in the following
directory:
install_root\config\cells\cell_name\nodes\node_name
\servers\server_name |
 |
- For V4.0 releases:
- Include all of the files from the following directory:
install_root\logs |
 |
- A copy of XMLExport for the server configuration
- tracefile
- drwtsn32.log
- user.dmp
- All javacore*.txt files
- 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.
Steps to setup Microsoft Windows environment to generate DrWatson log
and Userdump files
- On the Start menu, click Run.
- Enter drwtsn32, and then click OK. (This will bring up
the DrWatson screen.)
- Type the location to where you want the Dr Watson log to be
stored in the field provided for Log File Path.
- Type the location and the file name where you want the
user.dmp file to be stored in the field provided for Crash
Dump.
- Make sure that the following options are checked in DrWatson screen:
- Dump Symbol Table
- Dump All Thread Contexts
- Visual Notification
- Create Crash Dump file
- For Windows 2003, "Crash Dump Type" option needs to be
set to NT4 compatible Full
- Click OK.
- Click Run on the Start menu.
- Enter drwtsn32 -i and click OK. This will enable
DrWatson to become the default debugger, and it will generate the DrWatson
log and Userdump when an application crashes.
- Run the application.
- If the preceding steps do not result in the creation of a
drwtsn32.log file or a user.dmp file, follow the
instructions in Java process exits without leaving a footprint in
WebSphere log files.
- Follow instructions to send
diagnostic information to IBM support.
