NAME

poold - automated resource
pools partitioning daemon
 

SYNOPSIS

poold [-l level]

DESCRIPTION

poold provides automated resource partitioning facilities. poold can be enabled or disabled using the Solaris Service Management Facility, smf(5). poold requires the Resource Pools facility to be active in order to operate.

The dynamic resource pools service's fault management resource identifier (FMRI) is:

svc:/system/pools/dynamic

The resource pools service's FMRI is:

svc:/system/pools

poold's configuration details are held in a libpool(3LIB) configuration and you can access all customizable behavior from this configuration.

poold periodically examines the load on the system and decides whether intervention is required to maintain optimal system performance with respect to resource consumption. poold also responds to externally initiated (with respect to poold) changes of either resource configuration or objectives.

If intervention is required, poold attempts to reallocate the available resources to ensure that performance objectives are satisfied. If it is not possible for poold to meet performance objectives with the available resources, then a message is written to the log. poold allocates scarce resources according to the objectives configured by the administrator. The system administrator must determine which resource pools are most deserving of scarce resource and indicate this through the importance of resource pools and objectives.

EXAMPLES

Example 1 Modifying the Default Logging Level

The following command modifies the default logging level to ERR:

# /usr/lib/pool/poold -l ERR

Example 2 Enabling Dynamic Resource Pools
