management interface. An interactive or programmatic interface through which one can
manage a subsystem and its objects. In some subsystems, a specific process is
dedicated to the management interface; in other subsystems, the process that provides
the management interface also performs other functions.
management process. The process through which an application issues commands to a
subsystem. A management process can be part of a subsystem, or it can be associated
with more than one subsystem; in the latter case, the management process is logically
part of each of the subsystems. The Subsystem Control Point (SCP) and PATHMON
are examples of management processes.
manager process. A particular process within a subsystem that is the target of a
command, the reporter of an error, or the manager of the subject of an event message.
message. A block of information, usually in the form of a structure, that is sent from
one process to another. See also SPI message.
name. An identifier by which an object in a network is recognized. DNS defines the
following kinds of names: subsystem-object, subsystem-object type, alias, alias type,
composite, composite type, group, domain, subsystem, and subsystem-manager
names.
name exporter. A multithreaded DNS process that exports names to multiple nodes by
replicating information about the names on those nodes. This process, named $ZDNX
by default, is responsible for all interaction with DNS on other nodes in the network.
(It is not a NonStop process pair.) See also exporter process.
name management. That aspect of system or network management that pertains to the
naming of objects, the organization of names on a node, the distribution of names
among nodes, and other issues related to names and naming.
name manager. The multithreaded management process through which applications
and DNSCOM request input/output to the DNS database on their behalf. This
NonStop process pair has the name $ZDNS, by default.
name resolution. The process of transforming an alias into a subsystem-object name.
network control node. A node responsible for management of objects on one or more
other nodes.
NetCommand. The command-line interface supplied by DSMS that provides users with
a single set of DSNM commands to manage any subsystem supported by DSMS. See
Distributed Systems Management Solutions (DSMS) and Distributed Systems Network
Management (DSNM).
NetStatus. The full-screen interface supplied by DSMS that provides users with
continuously updated views of the status of a system or an entire network of systems.
See Distributed Systems Management Solutions (DSMS).
Network Management Application (NMA). A term used to describe a management
application that manages networks and objects in a network. See management
application.
NMA. See Network Management Application.
