View JVM logs
The JVM logs are written as plain text files. Use either of two techniques to view the JVM logs for an application server:
- Use the dmgr console, which also supports viewing the JVM logs from a remote machine.
- Use a text editor on the machine where the logs are stored.
IBM recommends using the HPEL log and trace infrastructure. With HPEL, one views logs using the LogViewer command-line tool in PROFILE/bin.
- View the JVM logs from the dmgr console.
- Start the dmgr console.
- Click Troubleshooting > Logs and Trace in the console navigation tree. To view the logs for a particular server, click on the server name to select it, then click JVM Logs.
- Select the runtime tab.
- Click View corresponding to the log to view.
- View the JVM logs from the machine where they are stored.
- Go to the machine where the logs are stored.
- cd profile_root/logs/server_name directory and select SystemOut.log or SystemErr.log.
- Open the file in a text editor or drag and drop the file into an editing and viewing program.
