Library /sys$common/syshlp/sysmanhelp.hlb SET, ENVIRONMENT, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The SET ENVIRONMENT command defines the target nodes or cluster
    for subsequent commands. When invoked, the system management
    environment is the local node where you are running SYSMAN. You
    can change the environment to any other nodes in the cluster, the
    entire cluster, or any nodes or cluster available through DECnet.

    Designate an OpenVMS Cluster environment with the /CLUSTER
    qualifier. When specifying a nonlocal cluster, also include the
    /NODE qualifier to identify the cluster.

    If your environment consists of VAX and Alpha nodes, see the DO
    command for information about creating logicals to manage each
    platform as an environment.

    You can display the current environment with the command SHOW
    ENVIRONMENT. To adjust privileges and defaults for the current
    environment, use the SET PROFILE command.

    An environment exists until you exit from SYSMAN or establish
    another command context with the SET ENVIRONMENT command.
