Basic z/OS Tuning Using the Workload Manager (ES54G)



This is an intermediate course for z/OS system programmers, z/OS performance analysts, and z/OS performance administrators new to performance management for their z/OS system.

NOTE: Basic z/OS Tuning Using the Workload Manager (ES54G) is intended for individuals new to WLM and the z/OS performance area.


  • 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


  • 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 CICSAnalyze 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
