TS/MP 2.5 Pathsend and Server Programming Manual

Enable product A tool provided by HP that allows users to develop simple data management applications without
using a conventional programming language. The Enable product can generate SCREEN COBOL
programs for use with Enscribe databases.
Enscribe database
record manager
HP database management software that provides a record-at-a-time interface between servers
and a distributed database. See also NonStop SQL/MP.
event log file A file maintained by the Event Management Service (EMS) for logging of event messages.
Event Management
Service (EMS)
A part of DSM used to provide event collection, event logging, and event distribution facilities.
It provides for different descriptions of events for people and for programs, lets an operator or
application select specific eventmessage data, and allows for flexible distribution of event messages
within a system or network. EMS has an SPI-based programmatic interface for reporting and
retrieving events. See also event message.
event message A special kind of SPI message that describes an event occurring in the system or network. Event
messages are collected, logged, and distributed by EMS. See also Event Management Service
(EMS).
Expand
networking
software
THP software that can connect up to 255 NonStop systems into a single network.
expandability See scalability.
Extended General
Device Support
(GDSX)
A HP product that facilitates communication between general I/O devices and a PATHMON
environment by acting as a front-end or a back-end process.
extensible
structured token
In the Subsystem Programmatic Interface (SPI), a token with a value that can be extended by
appending new fields in later releases. The token is accessed through reference to a token map
containing field-version and null-value information, allowing SPI to provide compatibility between
different versions of the structure. See also simple token and token (definition 2).
external
PATHMON process
See external process.
external process A process in a different PATHMON environment from the process with which it is communicating.
For example, suppose a TCP managed by PATHMON process $PMB requests a link to a server
process in a server-class that is managed by PATHMON process $PMA. Both the TCP and
PATHMON process $PMB are external processes with respect to PATHMON process $PMA and
the server-class managed by $PMA.
external server See external process.
external TCP See external process.
fault tolerance The ability of a NonStop system to continue processing despite the failure of any single software
or hardware component within the system.
field-characteristic clause
In SCREEN COBOL, an ordered set of characters that specify the characteristics of a screen field.
file identifier (file
ID)
In the Guardian environment, the portion of a file name following the subvolume name. In the
OSS environment, a portion of the internal information used to identify a file in the OSS file
system. The two identifiers are not comparable.
file name In the Guardian environment, the set of node name, volume name, subvolume name, and file
identifier characters that uniquely identifies a file. This name is used to open a file and thereby
provide a connection between the opening process and the file. See also fully qualified file name,
partially qualified file name, OSS filename, and OSS pathname.
file system In the Guardian environment, the application program interface for communication between
a process and a file. A file can be a disk file, a device other than a disk, or another process.
1.
2. In the OSS environment, a collection of files and file attributes. A file system provides the
namespace for the file serial numbers that uniquely identify its files.
File Utility Program
(FUP)
A HP product that allows users to create, copy, purge, and otherwise manipulate disk files
interactively.
