Container Manager 1.0 supported the fair share scheduler (FSS) only. Container Manager 3.6 allows you to select the scheduler class, fair share or timesharing, when you create or modify a resource pool. The scheduler class determines the process priority, deciding which process runs next.
After you change a resource pool's scheduler class, any new processes for that resource pool changes to the resource pool's scheduler class. Container Manager does not change the scheduler class of a running process.
