Performance considerations

The tracker and the controller address spaces must be nonswappable. To do this, include the definition of their top load module, EQQMAJOR, in the program properties table (PPT). This PPT entry example is defined in a SCHEDnn member of SYS1.PARMLIB:

SCHEDnn example
PPT PGMNAME(EQQMAJOR) NOSWAP

The EQQMAJOR program must run in storage key 8, the default value.

To ensure prompt processing by Tivoli Workload Scheduler for z/OS and to avoid delays in the handling of event records, the tracker subsystem performance rating (that is, its dispatching priority) should match that of the JES subsystem.
