OL23: System i Structure, Tailoring, and Basic Tuning
DURATION: 2 days
SCHEDULED DATES: TBD – Contact Us for more Information
PURPOSE
This classroom course of two days explains how to balance the workload on the IBM i system to ensure optimum performance. Specifically, this course explains how to manage workloads, measure system performance, and tune the operating system to meet processing requirements. Hands-on exercises give you the opportunity to use the system functions that are available for controlling workload and tuning system performance. Evaluation criteria presented in this course are based on the latest information available from IBM development labs.
AUDIENCE
This is an intermediate course is designed for data processing managers, programmers, and analysts.
PREREQUISITES
You should be able to:
Start and stop the operating system
Start and stop subsystems
Manage job, message, and output queues
Describe security concepts and create user profiles
OBJECTIVES
After completing this course, you should be able to:
Manage jobs by:
Setting the appropriate system values
Modifying subsystem descriptions to fit the workload
Controlling batch jobs
Tailoring job descriptions to fit processing needs
Create unique environments for running jobs by:
Creating subsystems for special applications
Directing jobs to run in these subsystems
Developing job descriptions for special jobs
Tune the performance of the system by:
Setting up pools and activity levels to handle jobs
Tailoring execution parameters for job priorities
Evaluating current performance using information provided by the system
Changing system values and parameters as the workload changes
