Introduction to Dynamic Resource Pools

Dynamic resource pools provide a mechanism for dynamically adjusting each pool's resource allocation in response to system events and application load changes. DRPs simplify and reduce the number of decisions required from an administrator. Adjustments are automatically made to preserve the system performance goals specified by an administrator. The changes made to the configuration are logged. These features are primarily enacted through the resource controller poold, a system daemon that should always be 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 optimal performance with respect to resource consumption. The poold configuration is held in the libpool configuration. For more information on poold, see the poold(1M) man page.
