Chapter 8

Fair Share Scheduler (Overview)

The analysis of workload data can indicate that a particular workload or group of workloads is monopolizing CPU resources. If these workloads are not violating resource constraints on CPU usage, you can modify the allocation policy for CPU time on the system. The fair share scheduling class described in this chapter enables you to allocate CPU time based on shares instead of the priority scheme of the timesharing (TS) scheduling class.

This chapter covers the following topics.

To begin using the fair share scheduler, see Chapter 9, Administering the Fair Share Scheduler (Tasks).
