Basic z/OS Tuning Using the Workload Manager (WLM) Schulung

Learn to work with the Workload Manager (WLM)
Basic z/OS Tuning Using the Workload Manager (WLM)

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 via the WLM Interactive System Productivity Facility (ISPF) application. The course uses both z/OS hands-on lab exercises and RMF case studies to reinforce the concepts and techniques discussed in lecture.
