Capacity and workload variations
You can direct work to the required z/OS image by changing the destination specifications on the
applicable workstation definitions. If the work can be separated into logical units of processing
(for example, IMS™ BMPs, or DB2®), then consider permanently defining these operations to separate workstations. This
implementation can provide everyday benefits for processing in the primary center as well. For
example, if you define all the IMS™ BMPs to a processor
workstation reserved for that purpose, then you have more power to control the processing of
activities, such as:
- Controlled shut down for scheduled outages to the control region
- Varying the number of BMPs running concurrently depending on the time of day
- Responding to extended recovery facility (XRF) takeovers in cases where z/OS is unaffected
- Handling scheduling of operations during unscheduled outages.
