2.3.1 Understanding SYSMAN
SYSMAN centralizes system management, so that you, as system manager, can
manage nodes or clusters from one location. Rather than logging in to individual
nodes and repeating a set of management tasks, SYSMAN enables you to define
your management environment to be a particular node, a group of nodes, or
an OpenVMS Cluster environment. With a management environment defined,
you can perform traditional system management tasks from your local node;
SYSMAN executes these tasks on all nodes in the target environment.
2.3.1.1 Privileges Required
You must have the following to run SYSMAN:
• OPER and TMPMBX privileges
• A separate account with no more than 125 rights, or enough identifiers
removed from the current account so the total number of rights falls within
the appropriate range.
The rights limitation of 125 includes a minimum of three identifiers that are
granted during login when the process rights list is created:
A UIC identifier
A system identifier
At least one environmental identifier, depending upon the environment in
which the process is operating
2.3.1.2 Usage Restriction
If you run SYSMAN from an account with more than 125 rights identifiers, and
the environment is set to a remote node, the following error message is displayed:
SMI-E-RIGHTSLIM, Rights limit exceeded.
Note that this rights identifier limitation includes a minimum of three identifiers
besides the rights identifiers that are associated with a user authorization record:
• A UIC identifier
• A system identifier
• Depending upon the environment in which the process is operating, at least
one environmental identifier
To run SYSMAN, you must have either of the following:
• A separate account with no more than 125 rights identifiers
