iSeries Performance Analysis and Capacity Planning (OL95)

Format

Classroom

Duration

4.0 Day(s)

Description

This classroom course describes how to use the AS/400 performance monitor to gather performance data. You will learn how to use the IBM Performance Tools/400 reports, displays, and graphics to analyze system performance, and the capacity planner to estimate resource utilization and manage system growth. This course is written at the V4R3 level.

Audience

People responsible for performance analysis and capacity planning on AS/400 systems. Performance Tools/400 should be installed on at least one of your AS/400 systems. You do not have to have a RISC AS/400 to benefit from this course.

Prerequisites

Before taking this course, you should be able to:

- Use performance data from the WRKSYSSTS display to adjust pool sizes and activity levels in order to tune the system
- Recognize jobs with high resource utilization on the WRKACTJOB display
- Recognize major factors which could contribute to high faulting rates and resource conflicts
- List the major components of an AS/400 job
- Distinguish between active, long wait, and ineligible job states
- Describe the effect of run priority and timeslice on job performance.

This knowledge can be gained by attending Operating System/400 Structure, Tailoring, and Basic Tuning (S6023) or AS/400 Work Management and Basic Tuning (PS587).

Objectives

After completing this course, you should be able to:

- Describe the relationship between resource utilization and response time
- Start and end the Performance Monitor and print Performance Tools/400 reports
- Use Performance Tools/400 reports, displays, and graphics to analyze system and job performance
- Use the AS/400 capacity planner, BEST/1 for the AS/400, to assess the impact of changes in workload on response time, throughput and configuration
- Use Performance Tools/400 to analyze the effects of implementing techniques to enhance performance.
