Description

Do you need to know how to establish a practical performance management program for your z/OS system? This course is designed for new performance analysts to learn to work with the Workload Manager (WLM) in goal mode. Learn concepts of WLM and performance management in the z/OS system using the WLM.



Learn how to analyze Resource Monitoring Facility (RMF) reports and implement service definitions using the WLM Interactive System Productivity Facility (ISPF) application. The course uses z/OS hands-on lab exercises to reinforce the concepts and techniques discussed in lecture.



Hands-on labs



This course includes hands-on lab exercises. Each student team, working on their own z/OS system, will configure RMF, analyze RMF reports to find bottlenecks, and utilize the WLM dialogs to create goals and classification rules in a service definition that manages a supplied z/OS workload.

Objectives


  • Describe a performance and tuning methodology

  • Develop a systematic z/OS performance and tuning plan

  • Describe the factors which could affect the performance of an z/OS system

  • Use the WLM ISPF application

  • Describe the components of a service definition

  • Define workloads and service levels and classification rules

  • State which z/OS commands affect WLM operation

  • Identify the major WLM services for z/OS, including enclaves and application environments, and how they are used by DB2, WebSphere, and CICS

  • Analyze CPU performance when running in a shared LPAR environment

  • Utilize and monitor zIIP and zAAP specialty engines

  • Measure and tune z/OS DASD, processor storage, and coupling facility configurations

  • Explain the functions and facilities of RMF and SMF

  • Analyze performance bottlenecks using RMF

  • Use Workload License Charges (WLC), defined capacity and soft capping to manage software costs

  • Describe advanced z/OS environments that utilize Intelligent Resource Director (IRD), HiperDispatch, z/OSMF Workload Management, and I/O Priority Manager

  • Use the z/OSMF Workload Management (WLM) task

    • Use Performance Monitoring with z/OSMF

    • Modify a WLM service definition to meet the requirements for monitoring a specific system workload

    • Create and customize Monitoring Desktops

    • Review any issues by using the Monitoring Desktops options displays

    • Assess the performance of the workloads running on the z/OS



Participants

This is an intermediate course for z/OS system programmers, z/OS performance analysts, and z/OS performance administrators new to performance management for their z/OS system.



Note: ES54 is intended for individuals new to WLM and the z/OS performance area
