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

Overview

The RMFZIC query charts the hourly actual zIIP engine use and zIIP engine eligible use for both the Central Processing Complex (CPC) and the z/OS LPARs using the shared engine pools of a CPC. Only PR/SM managed z/OS LPARs are charted. Non-z/OS LPARs and z/OS LPARs managed by VM are excluded from analysis because the data containing zIIP engine demand is not available.

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

The CPC level chart shows total zIIP engine demand, with the actual use and eligible demand stacked. The horizontal reference line in the CPC level chart shows the number of physical zIIP engines in the CPC shared engine pool.

The LPAR level chart shows zIIP engine use and zIIP engine demand as separate vertical bars for each hour of the day. The horizontal reference line in the LPAR level chart shows the number of logical zIIP engines assigned to the LPAR. One LPAR level chart is produced for each LPAR that executed zIIP eligible work.
