CA MICS Hardware and SCP Analyzer (RMF) Queries › Mainframe CPC Specialty Engine Focus › RMFZAS – Daily zAAP Engine Use and Demand by Service Class › Overview

Overview

The RMFZAS query charts the hourly total zAAP engine demand (actual zAAP engine use plus zAAP engine eligible use), by WLM Report Class, for the Central Processing Complex (CPC) and individual z/OS LPARs using the shared engine pools of a CPC. Only PR/SM managed z/OS LPARs contribute to these charts because the data containing zAAP engine demand, extracted from the WLMSEC Report Class Resource Consumption file, is derived from RMF type 72-3 records, which only record zAAP engine demand for PR/SM managed z/OS LPARs.

The example shows the CPC level chart (top) for an IBM z10 2097-712 CPC, and one of the individual LPAR charts for an LPAR defined to that CPC.

Both the CPC level and SYSID level charts show total hourly zAAP engine demand, using vertical bars, stacked by WLM Report Class.

Note: A fake Report class named ‘*NO ZAP*’ is created, showing no usage, for hours where there was no zAAP engine demand. This class prevents charts from being produced where hours are missing from the X-axis.
