PrefaceThis book describes how to use IBM Tivoli Decision Support for z/OS (hereafter referred to as Tivoli Decision Support for z/OS) and the CICS Performance feature to collect and report performance data generated by CustomerInformation and Control System (CICS).This book:v Helps you understand general performance characteristicsv Describes performance issues and how they affect the level of services you canoffer usersv Guides you through the component-selection, installation, and implementationprocessesv Explores performance characteristics shown in Tivoli Decision Support for z/OSreports so that you can analyze the characteristics of your systemThe terms MVS , OS/390, and z/OS are used interchangeably throughout thisbook.Who should read this bookThe CICS Performance Feature Guide and Reference is for:v Anyone who analyzes or monitors CICS performancev Anyone responsible for establishing or meeting service-level objectives for CICSuser groupsv Tivoli Decision Support for z/OS administrators (primarily as a guide to featureinstallation and as a reference to table and report definitions)v Users with various backgrounds who are interested in analyzing CICSperformance data and improving CICS performanceThe Tivoli Decision Support for z/OS CICS Performance feature helps you monitorCICS, even if you have little experience with CICS. However, to make the best useof the CICS Performance feature to improve CICS performance, you should knowCICS, the terms that are unique to CICS, and the terminology associated withdatabase design and performance. (If you are not familiar with CICS, refer to theCICS General Information manual which describes the basic concepts of CICS andintroduces you to some CICS terminology.)Also, the better you understand the interaction of processor cycles, storage, andI/O, the easier it is to identify performance constraints. The CICS product library(specifically the Performance Guide and the Customization Guide for eitherCICS/Enterprise Systems Architecture (CICS/ESA) or CICS/Multiple VirtualStorage (CICS/MVS) is the authoritative source for information aboutunderstanding and tuning CICS performance.Note: For information about licensed programs either required or recommendedfor use with Tivoli Decision Support for z/OS, refer to the Administration Guide andReference.xi
What this book containsWhat this book containsUse this book for guidance in collecting CICS-generated performance data fromSMF logs and creating the reports supplied with the CICS Performance feature.This book explains how to create and display Tivoli Decision Support for z/OSreports to both monitor and understand CICS performance.This book contains the following parts:v Use Part I, "Guide" for developing and executing your performance andservice-level strategy:– Chapter 1, “Introducing the CICS Performance feature,” on page 3 explainsbasic concepts of systems management and offers suggestions on establishingperformance objectives and service-level agreements. It also describes theCICS Performance feature's role in the Tivoli
