DSM Management Components
DSM defines two kinds of management interfaces to subsystems:
•
Command/response interfaces perform operations on subsystem-defined objects.
•
Event messaging interfaces report significant events detected by the subsystem.
Commands and responses provide a two-way interface: the operator or network
manager sends a command to a subsystem, and the subsystem performs an action
and returns a response to the operator. Event messages provide a one-way interface
from the subsystem to the operator or to the event-management application.
The Subsystem Control Facility (SCF) is an interactive interface that allows you to
send DSM commands to HP NonStop
™ data communications subsystems, including
OSI/MHS. SCF communicates with subsystems through a management process called
the Subsystem Control Point (SCP). The Event Management Service (EMS) provides
for event-message collection and distribution. You can use EMS to store and print
selected event messages; applications like ViewPoint let you display event messages
on the screen.
In addition to these interactive interfaces, DSM provides programmatic interfaces for
sending commands and receiving responses (control and inquiry), retrieving event
messages (event management), and generating and validating authentication
parameters (password server interfaces). The control and inquiry interface makes
available the same set of operations possible through SCF. The event management
interface lets your application receive, filter, process, and potentially display event
messages, either as they occur or in retrospect. The password server programmatic
interfaces let your application provide custom security services; in addition to the
password server programmatic interfaces, HP provides a master password server that
