Advanced z/OS Performance: WLM, Sysplex, UNIX Services, and Web (ES85G)



z/OS Systems Programmers, experienced Performance Analysts and Performance Administrators, UNIX Services support personnel, and other experienced I/S professionals who want to update their RMF and performance management skills to include the latest z/OS e-business runtime environments.


A working knowledge of the z/OS operational environment is assumed, including a basic knowledge of WLM, UNIX System Services, and Parallel Sysplex. Previous experience and/or training in z/OS measurement and tuning and RMF are also assumed. Such training can be obtained by attending course ES54 "Basic z/OS Tuning Using the Workload Manager (WLM)"

  • Basic z/OS Tuning Using the Workload Manager (WLM) !IB-ES54D0DE


  • Describe the advanced performance components of current complex z/OS environment and identify the major performance factors for these components
  • Identify Coupling Facility (CF) technologies and how they function in a Parallel Sysplex, including CF links and CF structures
  • Monitor and analyze the service times and other performance indicators of the CF and other Parallel Sysplex components, including Cross-system Coupling Facility (XCF)
  • Predict and monitor effects of system managed CF duplexing on system performance
  • Identify WLM services and their use by z/OS applications, including enclave services, routing services, and application environments
  • Evaluate RMF enclave reports and understand enclave resource accounting
  • Implement and control WLM optional features such as Intelligent Resource Director (IRD) and WLM defined capacity, and monitor LPAR performance when optimized by these features
  • Evaluate the use of Enterprise Workload Manager (EWLM) as an end-to-end workload management tool
  • Describe the new functionality introduced by zAAP and zIIP specialty processors on z/OS systems and use appropriate tools to control and monitor specialty CP workload performance
  • Monitor and control the USS program environment using RMF reports and System Management Facility (SMF) data along with USS console commands and displays
  • Tune USS resource usage, shell performance and file system performance for Hierarchical File System (HFS) and zFS
  • Configure WLM's management of the USS environment, including BPXAS and classification of USS workloads
  • Set up WLM management of the HTTP Server and classify a Web workload in standalone mode
  • Evaluate the performance implications of different network front-end options that can control access to z/OS web applications hosted in WebSphere
  • Describe a WebSphere Version 6 runtime on z/OS, and identify the basic steps for the performance tuning of this environment
  • Describe the distributed monitoring functionality for WebSphere provided by IBM Tivoli Composite Application Management
