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 Tandem 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-name expansion. The expansion of a partially qualified Guardian file name for a disk
file to include the associated node, volume, and subvolume names.
file system. (1) 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. (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 Tandem product that allows users to create, copy, purge, and
otherwise manipulate disk files interactively.
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.
