POOLD(8) Maintenance Commands and Procedures POOLD(8)

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(7). 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

ALERT
A condition that should be corrected
immediately, such as a corrupted system
database.


CRIT

errors.


ERR

WARNING
Warning messages.


NOTICE
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.

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
