Advanced z OS Performance: WLM, Sysplex, UNIX Services, z Systems





  • 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
  • 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
  • Describe the purpose of the Unified Resource Manager and the various system layers that it can work across
  • Describe what workload resource groups or workloads mean within the zEnterprise environment
  • Describe what performance management capabilities Unified Resource Manager provides
  • Describe the role Guest Platform Management Provider and Application Resource Measurement technologies play in the zEnterprise environment
  • Explain how zEnterprise technologies cooperate with z/OS Workload Manager (WLM)
  • Describe Unified Resource Manager performance functions
  • Know how to use RMF XP the solution for Cross Platform Performance Monitoring (z/OS and distributed platforms)
  • Use RMF XP for monitoring all operating systems running on the IBM
  • zEnterprise Blade center Extension

This advanced course is for 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 and zEnterprise ensemble 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 or training in z/OS measurement and tuning and RMF are also assumed. Such training can be obtained by attending course: Basic z/OS Tuning Using the Workload Manager (WLM) (ES540)
