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. You can redirect the JVM output to all the registered log destinations, such as the server terminal console and log file.
Note: If you redirect JVM standard out and standard error messages to the WebLogic logging service, messages are redirected asynchronously. In the event of an overload situation, these messages may be dropped. In addition, redirecting messages in high volume can have a significantly negative impact on system performance and is therefore not recommended. As a best practice for capturing JVM messages, Oracle recommends using one of the supported logging APIs instead. For more information, see Redirecting JVM Output.
