    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 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

    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
