Special Note
Today z/OS supports many workloads running as servers, including CICS, IMS, DB2, the IBM HTTP Server and the WebSphere Application Server. These workloads exploit the latest features of the z/OS runtime environments, including Parallel Sysplex, Workload Manager WLM), Unix System Services (USS), Intelligent Resource Director (IRD), and zIIP and zAAP specialty engines.

Examine the performance management and monitoring components of the Parallel Sysplex, USS, and WLM environment, using extensive Resource Management Facility (RMF) reports and console displays to understand what is happening in the system. Based on this foundation, analyze case studies involving Parallel Sysplex, Unix Workloads and the HTTP Server in detail, giving you a complete picture of a z/OS runtime. Finish with an introduction to performance and tuning with WebSphere Application Server Version 6 for z/OS, including a detailed look at web front-end options for the WebSphere Application Server.

This is an advanced course for z/OS system programmers, experienced performance analysts, performance administrators, USS support individuals, and other experienced Information System (I/S) professionals, who want to update their RMF and performance management skills to include the latest z/OS e-business runtime environments.

Skills Taught
  • 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)
  •  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 HFS and zFS file system performance
  • Configure WLM's management of the USS environment, including BPXAS and classification of USS workloads
  • Identify WLM services and their use by e-business applications, including enclave services, sysplex routing services, and application environments
  • Evaluate RMF enclave reports and understand enclave resource accounting
  • Set up WLM management of the HTTP Server and classify a Web workload in both standalone mode and scalable mode
  • Describe a WebSphere Version 6 runtime on z/OS and identify the basic steps for the performance tuning of this environment
  • Configure Intelligent Resource Director (IRD) to allow WLM to manage resources across LPAR's in a Parallel Sysplex
  • Understand WLM's management of Defined Capacity in conjunction with Variable Software License Charges
  • Describe the functionality of Enterprise Workload Manager (EWLM) in a distributed, multi-server environment
  • Understand and monitor the utilization of zIIP and zAAP speciality engines on System z processors
  • Differentiate between web front-end options for the Websphere Application Server

Tuning Parallel Sysplex
  • identifie CF technologies and how they function in a Parallel Sysplex
  • monitor and analyze service times and other performance indicators of the CF and other Parallel Sysplex components
  • exercise: based on specific RMF reports, identify and interpret key Parallel Sysplex indicators through a series of case study questions


Monitoring and tuning USS

WebSphere Application Server for z/OS Version 6 introduction and performance management

  •  introduce WebSphere Application Server for z/OS Version 6, looking at components, configuration options, and the runtime environment
  • tune the WebSphere Application Server (WAS) runtime, examine tuning z/OS, tune the WebSphere runtime, and exploit WLM to manage WebSphere performance
