TS/MP Pathsend and Server Programming Manual (H06.05+, J06.03+)

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 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.
file-name
expansion
The expansion of a partially qualified Guardian file name for a disk file to include the associated
node, volume, and subvolume names.
fixed-function
terminal
A nonintelligent device (that is, a device without processing ability) capable of sending and
receiving information over communications lines. Fixed-function terminals are often referred to
as dumb terminals.
freeze condition A condition in which communication between a terminal and a server class is prohibited. See
also thaw condition.
front-end process A process, such as the process that accepts the TCP terminal-data stream, that serves as the
intermediary between one system, process, or device and another.
fully qualified file
name
The complete name of a file in the Guardian environment. For a permanent disk file, this consists
of a node name (system name), volume name, subvolume name, and file identifier (file ID). In
interactive interfaces such as PATHCOM and TACL, the parts of a file name are separated by
periods. See also partially qualified file name.
gateway process A process, such as the Transaction Delivery Process (TDP) that is part of RSC/MP, that manages
communications between dissimilar environments (for example, a workstation and a NonStop
system). A gateway process both transfers information and converts it to a form compatible with
the protocols used by the destination environment.
GDSX See Extended General Device Support (GDSX).
graphical user
interface (GUI)
A type of screen interface that typically includes pull-down menus, icons, dialog boxes, and online
help.
Guardian An environment available for interactive or programmatic use with the NonStop Kernel. Processes
that run in the Guardian environment use the Guardian system procedure calls as their application
program interface, and might also use related APIs such as the Pathsend and TMF procedure
calls. See also Open System Services (OSS).
Guardian
environment
The Guardian API, tools, and utilities. See also Guardian.
Guardian
operating
environment
See Guardian environment.
high PIN A process identification number (PIN) in the range 256 through 65535. See also process
identification number (PIN) and low PIN.
