DB2 9 for z/OS System Performance Analysis and Tuning  (CV950)

Format: Formation en classe avec formateur
Autres formats:
 
 

This classroom course explains how to monitor and tune DB2 9 for z/OS from a system point of view. CV950 replaces course code CF950.
 
This Course is Certified By IBM   Flex Training Savings
 

Compétences acquises
 
  • Describe DB2 processes as they relate to DB2 performance
  • Interpret DB2 Trace Output
  • Tune a DB2 subsystem
  • Provide good input to system programmers to allow them to effectively tune the z/OS system for best DB2 performance

These objectives are met by discussing how to:

  • Monitor and control the DB2 workload
  • Monitor and tune IMS/CICS/DDF performance
  • Monitor and tune DB2 buffer pools, EDM pool, logging and IRLM execution
  • Tune DB2 attachments, including the DB2 side of distributed requests
  • Analyze bottlenecks
  • Communicate with systems people about DB2-related issues
  • Communicate with application developers on DB2 performance topics
  • Interpret DB2 statistics and accounting traces
  • List guidelines which enhance DB2 system performance
  • Understand how DB2 works well enough to be able to react effectively to many situations

Qui peut en profiter
 

This advanced course is for DB2 system tuners, Enterprise capacity planners and System programmers

DB2 9 for z/OS System Performance Analysis and Tuning  (CV950) Contenu détaillé
 
 
DB2 system performance analysis and tuning introduction
  • Identify why some z/OS concepts and controls have important influences on DB2 performance
  • Learn how DB2 works to enable effective monitoring and tuning of DB2
The DB2 trace
  • Set up and handle DB2 traces for both continuous monitoring and problem analysis
  • Determine, depending on the situation, whether to start with Statistics or with Accounting reports
  • Decide how to monitor and tune in your environment
  • List basic principles of reading and understanding monitor reports
Introduction to the operating system and hardware
  • Discuss operating system and hardware topics with other systems people
  • Identify the features and limits of specified hardware
  • Contrast reports originating from DB2 with those originating from the operating system
Service time, queuing time, case A transaction analysis
  • Analyze elapsed time components reported by accounting trace
    • Service versus queuing
    • Dominating components
    • Tuning potential
  • Analyze capacity bottlenecks with basic queuing theory
    • Estimate effect of software setup and hardware alternatives on elapsed time
Introduction and analysis of case E
  • Do an in-depth analysis of an accounting trace
The DB2 attachments
  • Obtain accounting information from the different environments (TSO, CICS, IMS, and so forth)
  • Recognize accounting anomalies that may occur
  • Take measures to increase/decrease the maximum amount of work that can flow into DB2
  • Take measures to prevent query users from overloading your system
  • Apply performance options in the CICS, IMS and Distributed interfaces to DB2
In-depth application of the DB2 system
  • Monitor current usage (behavior) of the most important parts of DB2
  • Differentiate between good and bad behavior
  • Perform DB2 system level tuning
  • Assist application developers in exploiting selected DB2 system level features
  • Identify things application developers should not do
 
The disk subsystems and DB2 I/O
  • Identify how disk I/O works for DB2 operations
Capacity analysis and massive batch
  • Predict the effect of tuning actions and hardware changes
  • Identify the issues of running massive batch jobs in parallel with performance-critical transactions
