iSeries (AS/400) Work Management

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:

• State the different resource requirements for the different types of job on the iSeries.
• Analyse and categorise the jobs running on the iSeries.
• Change major system parameters to control work management.
• Create work environments for specific jobs.
• Use priorities for jobs effectively.
• Measure and analyse system throughput.
• Decide whether to use system tuning or manual tuning.
• Carry out manual system tuning.

Who should attend

This course is intended for operators, senior operators, system programmers, shift leaders and technical support staff who have the responsibility for tuning 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 OR this course, as there is a significant overlap between the courses.

Materials

A course manual with supporting documentation is provided. The practical sessions allow delegates to create a work environment to segregate high, medium and low priority tasks, and to measure these running on the system. Delegates also have an opportunity to use some of the more recent facilities to improve system throughput.
