Distributed Systems Management
oriented programmatic interface has one definition file for DDL and one for each
programming language. Some subsystems—for instance, data communications
subsystems—have additional, shared definition files. See also SPI standard definitions,
data communications standard definitions, or EMS standard definitions.
Distributed Systems Management. A set of tools used to manage 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 NonStop subsystems.
distributor. An EMS process that distributes event messages from event logs to requesting
management applications, to Guardian console message destinations, or to a collector
on another node. See also consumer distributor. and compatibility distributor. Contrast
collector.
DNS. See Domain Name Server (DNS).
Domain Name Server (DNS). A method for naming resources. The basic function of the
domain name server is to provide information about network objects by answering
queries.
Domain. In the Internet, a part of the naming hierarchy. Syntactically, a domain name
consists of a sequence of names (labels) separated by periods (dots).
DSM. See Distributed Systems Management.
E4SA. See Ethernet 4 ServerNet adapter (E4SA).
ECHO. The name of a program used in the Internet to test the reachability of destinations by
sending them an ICMP echo request and waiting for a reply.
EGP (Exterior Gateway Protocol). The protocol used by a gateway in one autonomous
system to advise the Internet addresses of networks in that autonomous system to a
gateway in another autonomous system. Every autonomous system must use EGP to
advertise network reachability to the core gateway system.
empty response record. In DSM programmatic interfaces, a response record containing
only a return token with a value that means “no more response records.” See also
return token.
EMS. See Event Management Service (EMS).
EMS standard definitions. The set of declarations provided by EMS for use in event
management, regardless of the subsystem. Any application that retrieves tokens from
event messages needs the EMS standard definitions. See also definition or definition
files. Comparedata communications standard definitions or SPI standard definitions.
