Use the administrative console to enable tracing at a server's
startup. You can use trace to assist you in monitoring system performance
and diagnosing problems.
About this task
The diagnostic trace configuration settings for a server
process determines the initial trace state for a server process. The
configuration settings are read at server startup and used to configure
the trace service. You can also change many of the trace service properties
or settings while the server process is running.
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.
