Basic z/OS Tuning Using the Workload Manager

Do you want to know how to create a practical performance management program for your z/OS system? This course is designed for new performance analysts who want to learn how to work with Workload Manager (WLM) in target mode. Learn WLM concepts and how to manage performance on your z/OS system using WLM.

Issues

In this course we will discuss:

Describing performance and tuning methodologies
Develop a systematic z/OS performance and tuning plan
Describing factors that can affect z/OS system performance
Using the WLM ISPF application
Describing the components of a service definition
Defining load and service levels and classification rules
Determine which z/OS commands affect WLM operation
Identify the main WLM services for z/OS, including enclave and application environment, and how they are used by DB2, WebSphere and CICS
Analyze CPU performance when running in a shared LPAR partition environment
Use and monitoring of specialized zIIP and zAAP engines
Measure and adjust z/OS DASD configurations, processor storage and coupling objects
Explaining the functions and objects of RMF and SMF
Analyzing the performance bottleneck with RMF
Using load license fees (WLC), defined capacity and soft cap to manage software costs
Describing advanced z/OS environments that use Intelligent Resource Director (IRD), HyperDispatch, z/OSMF Workload Management and I/O Priority Manager
Using jobs from/OSMF Workload Management (WLM)

Using performance monitoring with z/OSMF

Modify the WLM service definition to meet the requirements for monitoring a specific system load
Create and customize monitored dashboards
Review any problems using the monitored dashboards option
Evaluating the performance of workloads running on z/OS

Who is this training for?

This is an intermediate course for z/OS developers, z/OS performance analysts and z/OS performance administrators who are new to the adventure of managing the performance of their z/OS system.

**Note**: The ES54 is designed for people who are new to WLM and the z/OS performance area.
