(Alpha Galaxy platforms only) The GALAXY parameter sets memory
    sharing.

    Specify one of the following:

    Value    Description

    0        The default. Do not participate in a memory sharing.

    1        Participate in a memory sharing.

    When you set GALAXY to 1 in a hard partition, OpenVMS instances
    will share memory between soft partitions within that hard
    partition. (You can run more than two soft partitions in a hard
    partition, and you might might not want to share memory among all
    of them.) Note that GALAXY specifies only if a node uses shared
    memory. You do not need to use the parameter to run multiple
    cooperative instances of OpenVMS; you do this by console setup of
    the configuration tree that you want.
