 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 vebosity level for logging information.
Specify level as ALERT, CRIT, ERR, WARNING,
NOTICE, INFO, and DEBUG. If level is not supplied, then

database.


CRIT

ERR

WARNING

Warning messages.


NOTICE

 Conditions that are not error conditions, but that may require special

INFO

Informational messages.


DEBUG

Messages that contain information normally of use only when debugging a

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
