View the JVM log files

The JVM logs are written as plain ASCII text files. By default, the JVM logs are located in the logs/servername subdirectory of the WebSphere instance you are using, where servername is the name of the server. If you are using the default WebSphere Application Server instance, the path is /QIBM/UserData/WebAS5/Base/default/logs/server1. If you are using the default Network Deployment instance, the path is /QIBM/UserData/WebAS5/ND/default/logs/dmgr. For a WebSphere Application Server instance that has been added to a Network Deployment domain (cell), the log files for the node agent are located in subdirectory logs/nodeagent and the logs files for the JMS server are located in subdirectory logs/jmsserver.

You can view the JVM log files using one of the methods listed below. For information on interpreting the contents of the logs, see Interpret the JVM logs.

• View the JVM logs from the administrative console.
  Perform these steps to view the JVM logs using the administrative console:
  1. Start the administrative console.
  2. Expand Troubleshooting.
  3. Click Logs and Trace.
  4. Click the link for the server whose logs you wish to view.
  5. Click JVM Logs.
  6. Select the Runtime tab.

  7. Click View for the log you want to view.

• View the JVM logs on the iSeries where they are stored.
  To use the Edit File (EDTF) CL command to view the JVM log files:
  From the OS/400 command line, invoke the EDTF CL command specifying the Integrated File System pathname for the file you wish to view. For example:

  EDTF FILE('/QIBM/UserData/WebAS5/Base/default/logs/server1/SystemOut.log')
  EDTF FILE('/QIBM/UserData/WebAS5/Base/default/logs/server1/SystemErr.log')

• From a non-iSeries workstation.
  Perform these steps to view the JVM logs from a mapped or mounted driver:
  1. Map (Windows 32-bit workstation) or mount (Unix workstation) a drive to the iSeries.
  2. Open the file in a text editor or drag and drop the file into a file editing/viewing
  program.
