Identifying the workloads

To plan for WLM, you shall begin by identifying the workloads processed in your enterprise. The workloads are certain to be apparent in any underlying TOR–AOR–FOR configurations. Confirm that the current CICSPlex® SM configuration of CICS® systems supports the identified workloads.

In particular:
  • Routing regions and target regions from a single workload must be in the same CICSplex. That is, the supplied dynamic routing program cannot route transactions beyond the confines of the CICSplex. (It is possible to route transactions outside of the CICSplex by customizing the supplied dynamic routing program. Customization of the supplied dynamic routing program is described in Modifying dynamic routing.)
  • A routing region must be:
    • A CICS TS region.
    • A local MAS, that is, the routing region cannot be running on an MVS image on which there is no CMAS.
    • In only one workload, that is, the routing region can be associated with only one active workload specification at a time.
  • A target region can be:
    • a local MAS
    • in multiple workloads
    • any CICS system managed by CICSPlex SM
