Objective

• 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
