POOLD(1M) Maintenance 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 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.

OPTIONS


The following options are supported:

-l level
Specify the verbosity 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

# /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
