Understanding SYSMAN and OpenVMS Cluster
Management
The System Management utility (SYSMAN) provides two kinds
of support for OpenVMS Cluster management:
Cluster-specific commands, CONFIGURATION
SET and CONFIGURATION SHOW, that you can use to manage security
data and system time in a cluster
Access to DCL-level commands with the DO command,
which gives you the ability to apply a single DCL command across
an entire cluster, rather than having to enter the command on each
node
Each SYSMAN command requires a specific level of privilege.
For more information about each command, refer to the HP OpenVMS System Management Utilities Reference Manual: M--Z
