Solaris 9 Resource Manager

Solaris 9 Resource Manager provides improvements to the management of system resources. The resource manager features enable system administrators to do the following:

• Allocate computing resources on a system.

• Monitor how these resources are being used so that allocations can be adjusted if necessary.

• Generate extended accounting information on resource usage. This information can be used for capacity planning and billing.

The resource controls framework allows you to set constraints on the system resources that are consumed by processes and tasks. Tasks are collections of processes that are related to a single activity.

Resource pools provide a way to partition system resources, such as processors, and maintain those partitions across reboots. A new fair share scheduler (FSS) has been added that allows the fine-grained sharing of CPU resources on a system.

These features enhance your ability to manage how resources are allocated to applications in a server consolidation environment.

In the Solaris 9 release, the full functionality is administered through a command-line interface. Performance monitoring and the setting of resource controls can also be done through the Solaris Management Console.
