Defines the nodes or cluster to which subsequent commands apply.

    Requires OPER or SETPRV privilege on all nodes in the target
    environment.

    Format

      SET ENVIRONMENT

1  –  Qualifiers

1.1    /CLUSTER

    Specifies that all subsequent commands apply to all nodes in
    the cluster. By default, the management environment is the local
    cluster. Specify a nonlocal cluster by naming one cluster member
    with the /NODE qualifier.

1.2    /NODE

       /NODE=(node1,node2,...)

    Specifies that SYSMAN execute subsequent commands on the given
    DECnet nodes. If accompanied by the /CLUSTER qualifier, the
    environment becomes the cluster where the given DECnet node is
    a member. A node name can be a system name, cluster alias, or
    logical name. However, before you can use logical names to define
    the command environment, you must set up the logical name table
    SYSMAN$NODE_TABLE. For more information about defining the SYSMAN
    logical name table, see the VSI OpenVMS System Manager's Manual.

1.3    /USERNAME

       /USERNAME=username

    Specifies that this user name should be used for access control
    purposes on another node. You can use this qualifier only in
    conjunction with the /CLUSTER or /NODE qualifiers. SYSMAN uses
    the current user name if none is supplied. SYSMAN prompts for a
    password whenever you specify a new user name.

                                   NOTE

       The account specified must have only a primary password.
       Accounts with secondary passwords are not supported.

2  –  Description

    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, Alpha, and Integrity server
    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.

3  –  Examples

    1.SYSMAN> SET ENVIRONMENT/CLUSTER
      %SYSMAN-I-ENV, Current command environment:
              Clusterwide on local cluster
              Username ALEXIS    will be used on nonlocal nodes

      This command defines the command environment as the local
      cluster. SYSMAN confirms the new environment.

    2.SYSMAN> SET ENVIRONMENT/NODE=NODE21/CLUSTER
      Remote Password:

      %SYSMAN-I-ENV, Current command environment:
              Clusterwide on remote node NODE21
              Username ALEXIS    will be used on nonlocal nodes

      This command establishes a management environment on the
      cluster where NODE21 is a member. SYSMAN prompts for a password
      because it is a nonlocal environment.

    3.SYSMAN> SET ENVIRONMENT/NODE=(NODE21,NODE22,NODE23)
      %SYSMAN-I-ENV, Current command environment:
              Individual nodes: NODE21,NODE22,NODE23
              Username ALEXIS   will be used on nonlocal nodes

      This command defines the management environment to be three
      individual nodes.

    4.$ CREATE/NAME_TABLE/PARENT=LNM$SYSTEM_DIRECTORY -
      _$ SYSMAN$NODE_TABLE
      $ DEFINE LAVCS SYS1,SYS2,SYS3,SYS4/TABLE=SYSMAN$NODE_TABLE
      $ RUN SYS$SYSTEM:SYSMAN
      SYSMAN> SET ENVIRONMENT/NODE=(LAVCS)
      %SYSMAN-I-ENV, Current command environment:
              Individual nodes: SYS1,SYS2,SYS3,SYS4
              Username ALEXIS   will be used on nonlocal nodes

      The commands in this example set up the logical name table
      SYSMAN$NODE_TABLE, define a logical name (LAVCS), and use the
      logical name to define the command environment.
