Distributed Name Service
Distributed Name Service. A subsystem for the NonStop server that manages a distributed
database of names. It allows you to store in your database the names (and aliases) of
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 HP NonStop™ systems and Expand networks. These tools include the
Subsystem Programmatic Interface (SPI), the Event Management Service (EMS), the
Subsystem Control Facility (SCF) for data communications subsystems, the Distributed
Name Service (DNS), the ViewPoint console application, the DSM Problem Manager
(DSM/PM), the DSM Template Services, and token-oriented programmatic interfaces
to the management processes for various NonStop subsystems as well as tools that
provide management services and assist in the development of management
applications.
distributor. An Event Management Service (EMS) process that distributes event messages
from event logs to requesting management applications, to console message
destinations, to a collector on another node, or to printers, devices, or files. See also
consumer distributor, compatibility distributor, forwarding distributor, and printing
distributor.
DNS. Abbreviation for Distributed Name Service.
downward compatibility. The ability of a requester to operate properly with a server of a
lower revision level. In this case, the requester is downward compatible with the server,
and the server is upward compatible with the requester. See also upward compatibility.
DSM. Abbreviation for Distributed Systems Management (DSM).
DSM Template Services. A software facility that is used to produce display text from
tokenized SPI messages. This facility is used most commonly to generate operator
console messages from EMS event messages, but it can also be used to generate
labels from SPI token values.
empty list or variable. A list that has no members, or a variable that has no content.
empty response record. A response record containing only the return token with a value
that means no more response records. See return token.
EMS. Abbreviation for Event Management Service (EMS)
.
EMS standard definitions. The set of declarations provided by the Event Management
Service (EMS) for use in event management regardless of the subsystem. Any
application that retrieves tokens from event messages needs the EMS standard
definitions. Names of EMS standard definitions start with ZEMS. See also definition
,
definition files, data communications standard definitions, and SPI standard definitions.
