Distributed Systems Management
Distributed Systems Management
Distributed Systems Management (DSM) is a group of software tools that enables you
to construct an integrated view of a system or network. DSM tools allow you to:
•
Manage your system from a single control point.
•
Distribute control of transaction processing among systems.
•
Retain a session with one subsystem (such as Pathway, TMF, or FUP) while
interacting with another subsystem.
•
Control different types of objects uniformly (objects can be of varying types,
including files, devices, and transactions).
•
Handle events (such as errors or changes in state) through a single mechanism,
regardless of which subsystem originated the event.
•
Build an integrated and uniform approach to problem determination, including
uniform reporting of events that call for operator action (for instance, a request that
an operator mount a tape); ways to tailor event reporting to your own needs; and
means for responding to events programmatically, without operator intervention.
For example, your program might receive notice of an error and respond by issuing
a command that corrects the error.
DSM consists of numerous components designed to handle varied functions. The parts
of DSM you can use with a Pathway subsystem follow:
•
The Subsystem Programmatic Interface (SPI)—a set of procedures that provides a
token-oriented interface between a management application and the central control
process within a subsystem (for example, a PATHMON process).
•
The Event Management Service (EMS)—a set of tools that collects and reports
events. In the Pathway subsystem, PATHMON reports errors and status changes
to EMS; the management application retrieves the event messages from EMS.
EMS also includes a filter language, which allows users to describe the subset of
messages an application wants to see. For more information about EMS, see the
EMS Manual.
•
The ViewPoint console application—a management application that allows
interactive communication with multiple HP NonStop products. Through a screen
display, you can summon PATHCOM as well as other interfaces such as
TMFCOM.
Using the ViewPoint application with the Pathway subsystem management
programming interface, you can control an integrated NonStop system, including
many subsystems, from one terminal. For more information about the ViewPoint
application, see the ViewPoint Manual.
•
The Distributed Name Service (DNS)—a subsystem that manages a distributed
database of names for network objects, facts about object relationships, and
instructions for replicating name definitions on remote nodes.
