Use the administrative console to enable tracing on a running
server. You can use trace to assist you in monitoring system performance
and diagnosing problems.
About this task
You can modify the trace service state that determines
which components are being actively traced for a running server by
using the following procedure.
You can also configure
tracing from the MVS™ console using the modify command.
Note: This topic references one or more of the application
server log files. As a recommended alternative, you can configure
the server to use the High Performance Extensible Logging (HPEL) log
and trace infrastructure instead of using SystemOut.log , SystemErr.log, trace.log, and activity.log files on distributed and IBM® i systems. You can also use
HPEL in conjunction with your native z/OS® logging facilities. If you are using HPEL, you can access
all of your log and trace information using the LogViewer command-line
tool from your server profile bin directory. See the information
about using HPEL to troubleshoot applications for more information
on using HPEL.
