This feature is new in the Solaris Express 1/04 release.
Dynamic resource pools (DRPs) provide a mechanism for adjusting each pool's resource allocation in response to system events and application load changes on systems that have resource pools enabled. Adjustments are automatically made to maintain the system performance goals specified by an administrator. Changes that are made to the configuration are logged.
These features are primarily enacted through the resource controller poold, a system daemon that is active when dynamic resource allocation is required. Periodically, poold examines the load on the system and determines whether intervention is required to enable the system to maintain the specified resource utilization goals. The daemon takes corrective action if possible, or the condition is logged.
