Subsystem-Specific Management Utilities
Certain communications subsystems, such as SNAX/HLS, Exchange/SNA, and
EM3270, have their own management utilities, which are not described in this section.
For more information about the utilities, consult the manuals for the products they
control.
Name Management
In a complex system or network, it is important for operators to be able to manage
subsystem resources without necessarily knowing the current names, locations, and
relationships of large numbers of objects. Rather, operators must be able to find out
about resource attributes and relationships—or be relieved of this burden by high-level
management applications.
On NonStop S-series servers you can store object names and other information about
objects in a database defined by the Distributed Name Service (DNS). DNS lets you
define
•
The subsystem with which an object is associated.
•
The management process that controls the object.
•
Object aliases that enable reference to the object by other than subsystem-defined
names, including local aliases for remote objects.
•
Groups of related objects. You decide which objects make up a group.
•
Composite objects (objects known to multiple subsystems) and attributes such as
which subsystems control the composite object and what those subsystems call
the object.
You can distribute the DNS database to provide for centralized or distributed network
control and to ensure the autonomy of any node in case the control node becomes
temporarily inaccessible. DNS is useful to operators and to developers of management
applications that integrate management of multiple products.
Control and Inquiry
To control the operational states of subsystem resources and to inquire about current
status—such as whether a line is up or down—you use the same tools that you do to
control the configuration; that is, you use SCF.
