file-system request.
file-system request. A request to the Guardian file system by or on behalf of a process.
Several different file-system requests are monitored for a process. You can view the
number of these requests that have occurred by issuing the SCF STATS PROCESS
command.
file storage system. An organized collection of files, including attributes and names,
residing on a computer system. On NonStop systems, the file storage system used is
the Guardian file system.
File Transfer, Access and Management. See FTAM (File Transfer, Access and
Management).
file-transfer-and-management service class. A service class that combines the services
of the file-transfer and file-management service classes. See file-transfer service class.
and file-management service class.
file-transfer service class. The service class that supports the movement of files or partial
files between independent computer systems on the network. The protocol for the
file-transfer class uses grouped operations that simplify data transfer.
File Utility Program. See FUP (File Utility Program).
filter. A NonStop file containing a list of criteria against which incoming EMS event
messages can be compared so as to pass a given message (if it met all criteria) or not
pass it (if it failed one or more criteria). See event message.
first-level data types. The lowest-level DDL structures, which serve as building blocks on
which DDL parameter structures are based.
format effectors. A class of control characters mainly intended for layout and positioning of
information on character-imaging devices, such as printers and video display terminals.
FTAM (File Transfer, Access and Management). A set of Application Layer services and
protocols used for manipulating files across an OSI network, as defined by the
ISO-8571 specification.
FTAM API. See API (application programmatic interface).
FTAM initiator errors. Locally generated errors returned when the return value on a
NonStop FTAM procedure call (shown in the NonStop FTAM manuals as status or
error, depending on the procedure) indicates an error. The value of status or
error indicates what occurred and how to proceed.
FTAM regime. The regime entered when you successfully establish an FTAM association.
In the FTAM regime, you can attempt to select or create a file, and you can terminate
or abort an association. See also data-transfer regime., file-selection regime., and file-
open regime.
