· Requisiti


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


Contenuti del corso

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.
