NAME

       pooladm - activate and deactivate the resource pools facility

SYNOPSIS

       /usr/sbin/pooladm [-n] [-s] [-c] [filename]  |  -x

       /usr/sbin/pooladm [-d | -e]

       The pooladm command provides administrative operations on pools and sets. pooladm reads the specified filename and attempts to activate the
       pool configuration contained in it.

       Before updating the current pool run-time configuration, pooladm validates the configuration for correctness.

       Without options, pooladm prints out the current running pools configuration.

       The following options are supported:

       -c              Instantiate the configuration at the given location. If a filename is not specified, it defaults to /etc/pooladm.conf.

       -d              Disable the pools facility so that pools can no longer be manipulated.

       -e              Enable the pools facility so that pools can be manipulated.

       -n              Validate the configuration without actually updating the current active files. Checks that there are  no  syntactic  errors
                       and  that  the configuration can be instantiated on the current system. No validation of application specific properties is
                       performed.

       -s              Update the specified location with the details of the current dynamic configuration.

                       This option requires update permission to the configuration that you are going to instantiate. If you use this option  with
                       the -c option, the dynamic configuration is updated before the static location.

       -x              Remove  the  currently active pool configuration. Destroy all defined resources, and return all formerly partitioned compo-
                       nents to their default resources.

       The following operands are supported:

       filename        Use the configuration contained within this file.

       Example 1: Instantiating a Configuration

       The following command instantiates the configuration contained at /home/admin/newconfig:

       example# /usr/sbin/pooladm -c /home/admin/newconfig

       Example 2: Validating the Configuration Without Instantiating It

       The following command attempts to instantiate the configuration contained at /home/admin/newconfig. It displays any error  conditions  that
       it encounters, but does not actually modify the active configuration.

       example# /usr/sbin/pooladm -n -c /home/admin/newconfig

       Example 3: Removing the Current Configuration

       The following command removes the current pool configuration:

       example# /usr/sbin/pooladm -x

       Example 4: Enabling the Pools Facility

       The following command enables the pool facility:

       example# /usr/sbin/pooladm -e

       Example 5: Saving the Active Configuration to a Specified Location

       The following command saves the active configuration to /tmp/state.backup:

       example# /usr/sbin/pooladm -s /tmp/state.backup

       /etc/pooladm.conf

       Resource bindings that are not presented in the form of a binding to a partitionable resource, such as the scheduling class, are not neces-
       sarily modified in a pooladm -x operation.

       The pools facility is not active by default when Solaris starts. pooladm -e explicitly activates the pools facility. The behavior  of  cer-
       tain APIs related to processor partitioning and process binding are modified when pools is active. See libpool(3LIB).

       You  cannot  enable the pools facility on a system where processor sets have been created. Use the psrset(1M) command or pset_destroy(2) to
       destroy processor sets manually before you enable the pools facility.
