Overview

IBM Tivoli[R] Performance Modeler for z/OS[R] V2.2 is a PC-based performance modeling and capacity planning tool that runs on Microsoft Windows. It can be as portable as your PC or laptop. IBM Tivoli Performance Modeler for z/OS V2.2 is designed for system management on the IBM zSeries[R] and System/390[R] (S/390[R]).

With growing operating system complexity and the huge impact of responding to workload changes, basic Central Processor Unit (CPU) utilization is generally no longer sufficient information for performing capacity planning. IBM Tivoli Performance Modeler for z/OS V2.2 can be used to model the impact of changing:

Number and speed of CPUs

Disk I/O response times

Paging rates (auxiliary and expanded memory paging)

Logical partition (LPAR) definitions and parameter changes

New in V2.2:

Support for modeling up to 40 workloads, up from 20 workloads within a single LPAR.

Support for modeling processors with up to 64 central processors. This includes support for modeling the IBM System z9 family of processors.

Support for zSeries Application Assist Processors (zAAPs). zAAP is an optional feature for zSeries 990 and zSeries 890.

Key prerequisites

Any PC that runs Microsoft Windows 2000 or Windows XP (recommended 300 MHz, or greater)

IBM z/OS Resource Measurement Facility (RMF), or equivalent software (such as CMF MONITOR from BMC Software)
