Schulung: IBM ES54G - Basic z/OS Tuning Using the Workload Manager
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 both z/OS hands-on lab exercises and RMF case studies to reinforce the concepts and techniques discussed in lecture.
describe the basc terms in the process of tuning and system structure
outline the tuning methodology, including the factors affecting performance and the individual steps in analyzing system performance
SMF and RMF
set up collection and utilize SMF data
implement and analyze RMF measurements for Monitors I, II, and III
utilize the RMF Spreadsheet Reporter and RMF Performance Management
CPU performance when running in a shared LPAR environment
utilize zSeries processor metrics and LPAR weights
analyze RMF CPU and LPAR reports
describe the functionality of zAAP processors
Basic system workload management
use WLM dialog to create/modify service definitions
create service class goals and classification rules to manage a complex z/OS workload
WLM commands, internals and services
understand the behavior and operation of WLM services, including enclaves, application environments, execution delay monitoring, and their use by DB2, WebSphere and CICS
optimize the use of WLM-managed initiators
Measure and tune z/OS DASD and processor storage
understand DASD configurations in order to analyze RMF DASD reports
interpret RMF paging and virtual storage reporting
Additional Topics - Coupling Facility, Intelligent Resource Director (IRD), Global Resource Serialization (GRS), Workload License Charges (WLC), and Enterprise Workload Manager (EWLM)
analyze RMF coupling facility reports through an understanding of how a CF operates in a parallel sysplex
understand the basic functionality, terminology and benefits of Intelligent Resource Director (IRD)
state how GRS operations can be tuned for optimal z/OS performance
utilize WLC, defined capacity, and the sub-capacity reporting tool to optimize software charges
describe how WLM implements soft capping
understand the operation and usage of EWLM and its relationship to z/OS WLM
