Planning for WLM

This section provides some instructions to help you determine the extent to which you can use CICSPlex® SM workload management in your enterprise.

Choosing between workload routing and workload separation
Use workload routing wherever possible because it makes the best use of the available CICS systems, and provides opportunities for increased throughput and improved performance. Implement workload separation (by process type, user, terminal, and transaction) only where strictly necessary because it prevents full exploitation of CICSPlex SM workload routing functions.
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.
Identifying inter-transaction affinities
Inter-transaction affinities, which require related transactions to be processed by the same target region, prevent optimum workload distribution. In general, they arise either because of the way in which one transaction passes data to another, or because of a requirement to coordinate the processing of two or more transactions. Identifying affinities isn't always easy, but there are some methods you can use.
