IBM i Performance Tuning I IBM i Structure Tailoring and Basic Tuning OL23G

This is an intermediate course is designed for data processing managers, programmers, and analysts.

• 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

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
