Workload separation

Workload separation is the WLM function that causes transactions which meet predesignated selection criteria to be routed to specific target scopes. The target scope for a separated workload item may vary from a single AOR to a large AOR group comprising many CICS regions. If an AOR group is the target, the balancing algorithm will be applied to select the most suitable region from those defined to it. To implement a workload that includes separated enterprise beans, you must first establish the prerequisite workload balancing described in Workload balancing. That configuration needs to be augmented with the following additional components:

This will allow the CICS and EJB environments to be established enabling enterprise bean separation. The WLM definitions will then need to be created to implement it. This entails identifying the cloned CIRP transactions as being objects of interest, and associating them with the required target scopes through a series WLM definitions. These WLM definitions must be associated to an overall WLM specification, via an intermediate WLM group, and then the specification must be added to the CICS group that includes all listeners and AORs that are to participate in the workload. A detailed example of enterprise bean workload separation is given in the CICSPlex® System Manager Managing Workloads.
