Do you need to know how to establish a practical performance management program for your z/OS system? This course is designed for new performance analysts to 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. The course uses z/OS hands-on lab exercises to reinforce the concepts and techniques discussed in lecture.
COURSE OBJECTIVE:
• 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 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)
TARGET AUDIENCE:
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 (ES54GB) is intended for individuals new to WLM and the z/OS performance area.
COURSE PREREQUISITES:
You should:
• Understand basic MVS / z/OS operation, such as job flow through JES, job scheduling paging, swapping, dispatching controls, 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
