Resource Controls

Simply assigning a workload unit to a resource unit is insufficient for managing the quantity of resources that users consume. To manage resources, the Solaris OS provides a set of flags, actions, and signals that are referred to collectively as resource controls and are stored in the /etc/project file. The Fair Share Scheduler (FSS), for example, can allocate shares of CPU resources among workloads based on the specified importance factor for the workloads. With these resource controls, a system administrator can set privilege levels and limit definitions for a specific project, task, or process. To learn how a system administrator uses resource controls, see Chapter 6, Resource Controls (Overview), in System Administration Guide: Solaris Containers-Resource Management and Solaris Zones. For programming considerations, see Chapter 5, Resource Controls.
