Do you need to know how to establish a practical performance management program for your z/OS system? New performance analysts can 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. Use both z/OS hands-on lab exercises and RMF case studies to reinforce the concepts and techniques discussed in lecture.

Hands-On Labs

Hands-on labs are included to address RMF configuration, analysis of RMF reports to find bottlenecks, and utilization of the WLM dialogs to create goals and classification rules in a Service Definition that manages a supplied z/OS workload. Teams also gain experience working with the RMF Spreadsheet Reporter and RMF Performance Monitoring.


You should be able to:

  • Understand basic z/OS operation, such as job flow through Job Entry Subsystem (JES), job scheduling, paging, swapping, dispatching controls and Input/Output (I/O) scheduling
  • Describe the purpose of the System Resources Manager (SRM) function in managing system workloads
  • Use the RMF performance-related reports to identify system performance problems

Delegates will learn how 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 Central Processing Unit (CPU) performance when running in a shared logical partitioned mode (LPAR) environment
  • Measure and tune z/OS Direct Access Storage Device (DASD), processor storage, and Coupling Facility (CF) configurations
  • Explain the functions and facilities of RMF and System Management Facility (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) and Enterprise Workload Manager (EWLM)
