Basic z/OS Tuning Using the Workload Manager [TDS_ES54G]

OVERVIEW

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.

Virtueel en Klassikaal™

Virtueel en Klassikaal™ is een eenvoudig leerconcept en biedt een flexibele oplossing voor het volgen van een klassikale training. Met Virtueel en Klassikaal™ kunt u zelf beslissen of u een klassikale training virtueel (vanuit huis of kantoor )of fysiek op locatie wilt volgen. De keuze is aan u! Cursisten die virtueel deelnemen aan de training ontvangen voor aanvang van de training alle benodigde informatie om de training te kunnen volgen.

OBJECTIVES

After this course participants should be able to:

• 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)

AUDIENCE
