CICSPlex SM WLM configuration at its simplest

The most basic WLM configuration provides workload balancing for all dynamic transactions and program links across CICS® systems in the target scope, and optionally honors a default affinity type and lifetime. It is possible to use workload management in CICSPlex® SM with a configuration that comprises simply a workload specification (WLMSPEC) to name the workload and to point it at a default set of regions to which work can be routed.

The following example shows a WLMSPEC called MYWLMSPC with a target scope of MYAORS. The target scope is a CICS systems group that contains the regions where work might be run. Here's how the WLMSPEC looks in CICS Explorer®:

Here's how it looks in the CICSPlex SM WUI:

Most situations will have more complex processing than the above example can handle. For example, you might not want all transactions to be routed to any target region. You probably want to name specific transactions for routing and you might well need some form of workload separation and workload affinities to be set up. These extensions do need some additional CICSPlex SM WLM artifacts to be configured, such as a workload management definition (WLMDEF), workload management group (WLMGROUP) and transaction group (TRNGRP) but you can build those up incrementally.
