VMS Help SHOW, LICENSE, Qualifiers, /USAGE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Tells you how many license units are loaded, how many are
    currently allocated, and how many are currently available, as
    well as the license type for each product on the system. Use with
    the /FULL qualifier to display complete information-including the
    PID, process name, node, or user name-for each instance of use
    of the product. You need group privilege to see the list of users
    in your group who have allocated license units; you need world
    privilege to see the list of users in all groups.

    In an OpenVMS Cluster, if you own multiple license types for a
    single product, you are limited to viewing the usage information
    for the license type loaded on the node from which you are
    executing the SHOW LICENSE/USAGE command. To find out the usage
    of the other license type loaded on another node, issue the
    command on that node. You can also use the System Management
    (SYSMAN) utility to do this.

    In an OpenVMS Cluster, usage information is limited to the local
    license type. For example, VAX and Alpha availability licenses
    are considered by LMF to be different license types. If you
    are running both VAX and Alpha systems in a cluster, usage
    information for availability licenses is limited to the local
    system type. For example, if you have DEC C installed on all
    nodes in your OpenVMS Cluster, you can display DEC C license
    allocation on all the VAX nodes in the cluster from any VAX node
    with DEC C installed, but you cannot display the DEC C license
    allocation on the Alpha nodes.

    Usage information is not available for unlimited licenses (a
    license with 0 units). Clusterwide usage information is not
    available for personal use or NO_SHARE licenses. Refer to the
    OpenVMS License Management Utility Manual for more information on
    license types.
