Basic z/OS Tuning Using the Workload Manager

Course code: ES54G

Duration: 4.5 Days

Prerequisite:

You should: 

•    Understand basic MVS and z/OS operation, such as job flow through JES, job scheduling paging, swapping, dispatching controls, and I/O scheduling
•    Have a basic knowledge of the purpose of the Workload Manager's function in managing system workloads
•    Be familiar with using TSO and ISPF to manage data sets and run batch jobs

Course Description:

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. 

Course Objectives:

After taking this course, you should be able to:

•    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

Intended Audience:

•    This is an intermediate course for people who need to write and maintain Rexx programs in the z/OS system environment.
