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

Overview

The RMFZIS query charts the hourly total zIIP engine demand (actual zIIP engine use plus zIIP engine eligible use), by WLM Service 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 zIIP engine demand, extracted from the WLMSEC Service Class Resource Consumption file, is derived from RMF type 72-3 records, which only record zIIP engine demand for PR/SM managed z/OS LPARs.

The example shows the following charts:

• CPC level chart (top) for an IBM z10 2097-712 CPC
• One of the individual LPAR charts for an LPAR defined to that CPC

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

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