Enabling tracing for administrative task scheduler problem determination

If you need to perform problem determination on the administrative task scheduler in response to a message, you can use a trace.

About this task

Use the MVS™ system command MODIFY to enable or disable tracing. When tracing is enabled, the trace goes to SYSOUT in the job output of the started task of the administrative task scheduler. The trace output helps IBM Support to troubleshoot problems.

Procedure

To enable tracing for problem determination:

  • To start a trace for an administrative task scheduler that is named admtproc, issue the following MVS system command:
    modify admtproc,appl=trace=on

    Substitute the name of your administrative task scheduler for admtproc.

  • To stop a trace for an administrative task scheduler that is named admtproc, issue the following MVS system command:
    modify admtproc,appl=trace=off 
  • To configure the system so that tracing starts automatically when the administrative task scheduler starts, modify the procedure parameter TRACE in the JCL job that starts the administrative task scheduler.
    This job has the name that was assigned when the administrative task scheduler was installed. The job was copied into one of the PROCLIB library during the installation. Specify TRACE=ON.

    To disable tracing, change the parameter to TRACE=OFF.
