poold - automated resource pools partitioning daemon
poold [-l level]
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:
The resource pools service's FMRI is:
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.
The following options are supported:
Specify the vebosity level for logging information.
Specify level as ALERT, CRIT, ERR, WARNING, NOTICE, INFO, and DEBUG. If level is not supplied, then the default logging level is INFO.
A condition that should be corrected immediately, such as a corrupted system database.
Critical conditions, such as hard device errors.
Conditions that are not error conditions, but that may require special handling.
Messages that contain information normally of use only when debugging a program.
When invoked manually, with the –l option, all log output is directed to standard error.
The following command modifies the default logging level to ERR:
# /usr/lib/pool/poold -l ERRExample 2 Enabling Dynamic Resource Pools
The following command enables dynamic resource pools:
# /usr/sbin/svcadm enable svc:/system/pools/dynamic
