Distributed Name Service (DNS) Management Operations Manual

system and network objects, facts about their relationships, and instructions for
replicating name definitions on remote nodes. The completed database, which you
update as needed to reflect configuration changes, is an online resource to operators
and management applications. The subsystem includes both an interactive text
interface (DNSCOM) and a programmatic command interface based on SPI.
Distributed Systems Management (DSM). A set of software tools that facilitate management
of NonStop systems and EXPAND networks. These tools include the Viewpoint
console application, the Subsystem Control Facility (SCF) for data-communications
subsystems, the Subsystem Programmatic Interface (SPI), the Event Management
Service (EMS), the Distributed Name Service (DNS), and token-oriented programmatic
interfaces to the management processes for various Tandem subsystems.
Distributed Systems Management Application (DSMA). A term used to describe a
management application. See management application.
Distributed Systems Management Solutions (DSMS). A Tandem application package with
two interfaces, NetStatus and NetCommand, and an underlying management service
layer, Distributed Systems Network Management (DSNM), that you use to monitor
and control systems and networks from a single terminal. DSMS is particularly useful
for managing subsystems and their objects.
Distributed Systems Network Management (DSNM). The management services layer of
DSMS that manages the interaction between subsystems supported by DSMS and the
DSMS NetCommand and NetStatus user interfaces. See also Distributed Systems
Management Solutions (DSMS), NetStatus, and NetCommand.
distribution. Apportionment of resources within a system or among nodes of a
network. It is proper to refer to distribution of an application or its processes, a
database or its data, memory, devices, workload, and so on. In the case of a database,
for instance the DNS database, distribution might imply partial replication of the
database at various locations.
DNS. See Distributed Name Service.
DNS database. The collection of all names defined to DNS, and their attributes.
DNS object name. An alias or a composite, domain, or group name.
DNS owner. The Guardian 90 user ID that owns a DNS configuration. By default, the
configuration is first initialized through this user ID.
DNS type name. An alias, subsystem object, or composite type name.
DNSCOM. An interactive program provided by DNS to install and initialize DNS on a
node, initially create the DNS database, control processes running under DNS, handle
inquiry and update operations against the DNS database, and to start, stop, and
determine the status of DNS.
domain. The set of nodes or processes under the control or within the scope of a
controlling process or a specific command. In DNS, the set of nodes on which DNS
replicates the initial definition of an alias, group, or composite name, or an update to
that definition; the user specifies the domain when he defines the name.
