iSeries (AS/400) Work Management and Performance

Introduction

This course is intended for IT staff responsible for configuring and managing the work environment, managing and monitoring system performance. The course covers creating subsystems and customising the system to manage workloads and optimise performance. How to monitor, what to monitor, collecting performance data, analysing the data using various tools, advanced options for tuning the system etc. Look at the new performance tools in IBM's Navigator for i browser based GUI.

Who should attend

This course is intended for operators, senior operators, system programmers, shift leaders and technical support staff who have the responsibility for managing and 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, Advanced Operations, or the iSeries System Facilities course or have the equivalent hands on experience. Note there is overlap with the Work Management topic in the System Management and Administration course.

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.
