DSM Facilities
OSI/AS supports Compaq’s Distributed Systems Management (DSM) facilities for
subsystem management. DSM provides two kinds of management interfaces to
subsystems: commands that perform operations on subsystem-defined objects, and event
messages that report significant events detected by the subsystem. The difference
between these two interfaces is as follows:
•
Commands provide a two-way interface: the operator, network manager, or
management application sends a command to a subsystem, and the subsystem then
performs some action and returns a response.
•
Event messages, on the other hand, provide one-way information from the
subsystem to the operator or management application.
The Subsystem Control Facility (SCF) is an interactive interface that allows you to send
DSM commands to Compaq data communications subsystems, including OSI/AS. SCF
communicates with subsystems via a process called the Subsystem Control Point (SCP).
The Event Management Service (EMS) provides an interactive and a programmatic
interface for event-message collection and distribution. These interfaces allow you to
display, store, and print selected event messages.
DSM also provides a programmatic interface for sending commands (control and
inquiry) and retrieving event messages (event management) via a process called the
Subsystem Programmatic Interface (SPI). This programmatic interface allows programs
to perform the same kind of monitoring and control operations that users of SCF and
EMS can perform interactively. For more information on these programmatic
management interfaces, see the OSI/AS Management Programming Manual and the
Event Management Service (EMS) Manual.
