poold(1M) System Administration Commands poold(1M) 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 configura- tion. 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 configura- tion 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 allo- cates 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. OPTIONS
The following options are supported: -l level 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. ALERT A condition that should be corrected immediately, such as a corrupted system database. CRIT Critical conditions, such as hard device errors. ERR Errors. WARNING Warning messages. NOTICE Conditions that are not error conditions, but that may require special handling. INFO Informational messages. DEBUG 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. 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 The following command enables dynamic resource pools: # /usr/sbin/svcadm enable svc:/system/pools/dynamic ATTRIBUTES
