Enabling trace at server startup
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.
