High Performance Extensible Logging mode
Starting in WebSphere Application Server V8, you can configure the server to use the HPEL
log and trace infrastructure. In prior versions, SystemOut.log, SystemErr.log, trace.log,
and activity.log files or native z/OS logging facilities were used for this logging. By default,
HPEL is not enabled. You can enable it from the administrative console or by using wsadmin
scripting.

scripting, see the Websphere Application Server V8.5 Infor
