CPSM Workload algorithm enhancement

Customers need IBM to develop an enhancement to the present CPSM Algorithm in order to save MLC (monthly license charge).

The current CPSM solution provides workload balancing which dynamically routes transactions among a set of target regions (AORs) observing information about the health of the AORs that CPSM maintains. For this route decision CICSPlex SM considers several criteria such as current and past SOS situations, AOR most likely to meet response time goal, AOR least likely to cause the transaction to abend, AOR with the shortest queue of transactions, etc. Thus CICSPlex SM tries to automatically avoid, by routing transactions away from, unreliable AORs.

The objective of this RFE is to include, into the already existing CPSM criteria for dynamic routing decision, the MSU idle capacity of the CECs where the CICS target regions reside in. This extra criterion should work combined with all existing ones, and must watch the 4-hour rolling window of CEC MSU usage threshold limit set arbitrarily by installation. When the current MSU consumption of a given CEC is running past the set threshold level, it must refuse incoming workloads to be sent to any AOR in the scope of LPARs within the subject CEC in order to exclude them from AORs selection list of routing decision even though they are healthy from CPSM perspective. When it decreases below the set threshold level, those AORs will be put back to that AORs selection list.
