CA MICS Hardware and SCP Analyzer (RMF) Queries › Mainframe CPC Engine Utilization › RMFICD – CPC and LPAR Daily Shared ICF Engine Dispatch by Hour › Overview

Overview

The RMFICD query creates a single data extract CSV showing hourly CPC and LPAR dispatch percentages for the shared ICF (Integrated Coupling Facility) engine pool. For each Central Processing Complex (CPC) in the DAYS timespan HARLPC file, the query generates a CPC level chart. The chart uses vertical bars to show the total and effective dispatch percentage of the physical ICF engines for each hour of the day—plus a horizontal reference line showing the total number of physical engines in the shared ICF processor pool. The CPC level chart is followed by individual charts for each LPAR in the CPC, showing the dispatch percentages of the logical ICF engines assigned to the LPAR. For the LPAR charts, the horizontal reference line shows the number of logical ICF engines active for the LPAR.

The difference between total and effective dispatch represents the amount of the engine resource pool required for multiprocessing management overhead.
