The JVM in which a WebLogic Server instance runs, sends messages to
standard error and standard out. Server as well as application code
write directly to these streams instead of using the logging mechanism.
Through a configuration option, you can redirect the JVM output to all
the registered log destinations, like the server terminal console and
log file. When enabled, a log entry appears as a message of NOTICE
severity. Redirecting the JVM output does not capture output from native
code, for example thread dumps from the JVM.
For example, to redirect the JVM standard out messages:
- When you start the Administration Server, include the following Java option in the weblogic.Server command:
See "weblogic.Server Configuration Options" in Command Reference for Oracle WebLogic Server.
- After the Administration Server has started, use the Administration Console to redirect the JVM standard out messages. See "Redirect JVM output" in the Oracle WebLogic Server Administration Console Online Help.
- Use the WLST to change the value of the RedirectStdoutToServerLogEnabled property of the LogMBean and re-start the server.
The WLST commands in Example 3-6 redirect the JVM standard out messages in the Administration Server to the server logging destinations. Read the full documentation here.
