Enabling trace on a running server
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.
