2.3 Using SYSMAN to Centralize System Management
2.3.4 Defining the SYSMAN Management Environment
To define the management environment, use the SYSMAN command SET
ENVIRONMENT. Whenever you redefine an environment, SYSMAN displays
the new context. You can always verify the current environment with the SHOW
ENVIRONMENT command.
When you are not working on your local node or within your own cluster, your
environment is a nonlocal environment. SYSMAN makes this distinction
for security reasons; when you are defining a nonlocal environment, such as a
different cluster, SYSMAN prompts for a password. SYSMAN also prompts for
a password when you attempt to manage a system under a different user name.
You can change your user name by using the /USERNAME qualifier with SET
ENVIRONMENT.
A SYSMAN environment remains in effect until you change it or exit from
SYSMAN.
2.3.4.1 Defining Another Node as the Environment
You can define a management environment to be any node available through
DECnet. To define one or more nodes to be your management environment, use
the SET ENVIRONMENT/NODE command.
For the following examples, refer to Figure 2–2; assume you are logged in to
NODE 21.
Examples
1.
$ RUN SYS$SYSTEM:SYSMAN
SYSMAN> SET ENVIRONMENT/NODE=NODE22
%SYSMAN-I-ENV, current command environment:
Individual nodes: NODE22
Username ALEXIS will be used on nonlocal nodes
The SET ENVIRONMENT command in this example defines the management
environment to be NODE22. (The command does not, however, set the
environment to be Cluster 1.)
2.
SYSMAN> SET ENVIRONMENT/NODE=(NODE23,NODE24,NODE25)
Remote Password:
%SYSMAN-I-ENV, Current Command Environment:
Individual nodes: NODE23,NODE24,NODE25
At least one node is not in local cluster
Username ALEXIS will be used on nonlocal nodes
The SET ENVIRONMENT command in this example defines the management
environment to be a group of nodes — NODE23, NODE24, and NODE25 —
that are in two separate clusters.
