iSeries (AS/400) Work Management and Basic Tuning

Introduction

The iSeries is capable of processing many different jobs with differing resource requirements at the same time. The work environment can be tuned to cope with these demands, and can provide increases in system throughput when tuned correctly.

What you will learn

On completion of this course, you will be able to:

• Define and customise the work environment.
• Understand how jobs process.
• Create, manage and modify subsystem descriptions.
• Manage storage pools and activity levels.
• Observe system performance.
• Carry out basic performance tuning.
• Collect performance data.
• Interpret performance data.
• Use iSeries Navigator monitors and graphs.

Who should attend

This course is intended for operators, senior operators, system programmers, shift leaders and technical support staff who have the responsibility for work management and performance on the iSeries.

Pre-requisites

Delegates attending this course should be experienced in the field of iSeries operations, or should attend either the iSeries OPERATIONS, or the iSeries SYSTEM FACILITIES course, followed by further practical experience. Delegates are advised to attend EITHER the iSeries SYSTEM ADMINISTRATION course, iSeries ADVANCED OPERATIONS, OR this course, as there is an overlap between the courses.

Materials

A course manual with supporting documentation is provided. The practical sessions allow delegates to create and tailor subsystems, monitor system performance and carry out basic tuning to improve response times and throughput. Use iSeries Navigator to monitor and improve system throughput.
