JES considerations

The JES type and configuration in your installation has implications on your Tivoli Workload Scheduler for z/OS configuration. Consider these situations:

1. On systems where JES2 is installed, a Tivoli Workload Scheduler for z/OS Tracker must be installed on each system in the JES2 Multi-Access Spool (MAS) complex.
2. If you do not install Tivoli Workload Scheduler for z/OS on all systems in a JES3 complex, ensure that:
   • A tracker is installed on the global.
   • Jobs are submitted, whether by Tivoli Workload Scheduler for z/OS or outside Tivoli Workload Scheduler for z/OS, to a system where a tracker is installed. Use the //*MAIN SYSTEM=sysid statement in the JCL, or start job classes used by these jobs only on those systems where a tracker is installed.
   • If you track print operations, output is printed only on those systems where a tracker is installed.
