Chapter 3. Operating NetView FTP V2.2.1 MVS - IBM

independent LU. A logical unit (LU) that does not
receive an ACTLU over a link. Such LUs can act as
primary logical units (PLUs) or secondary logical units
(SLUs) and can have one or more LU-LU sessions at a
time.
INI file. See initialization file.
initialization file. A file that contains parameters that
determine how NetView FTP for Workstations starts
running.
input field. An area on a panel in which data is
entered.
instance. In the AIX operating system, the concrete
realization of an abstract object class. An instance of a
widget or gadget is a specific data structure that contains
detailed appearance and behavioral information
that is used to generate a specific graphical object onscreen
at run time.
Internet. A wide area network connecting thousands of
disparate networks in industry, education, government,
and research. The Internet network uses /IP as the
standard for transmitting information.
Internet Protocol. A protocol used to route data from
its source to its destination in an Internet environment.
Intersystem communications function. Communications
between application programs on an AS/400
system and an application program on a remote system
are accomplished using the AS/400 system intersystem
communications function (ICF) and the underlying
support.
IP. Internet Protocol.
ISPF. Interactive System Productivity Facility.
JCL. Job control language.
JES. Job entry subsystem.
job allocation. The allocation of a file by a server
startup job. The allocation takes place when a server is
started, which is before (sometimes long before) the file
transfer takes place. Contrast with dynamic allocation.
job control language. A control language used to
identify a job to an operating system and to describe
the job’s requirements.
key sequence. In VSAM, the collating sequence of
data records as determined by the value of the key field
in each record.
key-sequenced data set. A VSAM data set whose
records are loaded in key sequence and controlled by
an index.
270 NetView FTP V2 MVS Installation, Operation, and Administration
keyword. A part of a control statement that consists of
a specific character string.
KSDS. Key-sequenced data set.
LAN. Local area network.
LAN gateway. A functional unit that connects a local
area network with another network using different protocols.
LDS. Linear data set.
LEN node. Low-entry networking node. That is a
node that provides a range of end-user services,
attaches directly to other nodes using peer protocols,
and derives network services implicitly from an adjacent
APPN network node, that is, without the direct use of
CP-CP sessions.
linear data set. A VSAM data set that contains data
but no control information. A linear data set can be
accessed as a byte-string in virtual storage. A linear
data set has no records and a fixed control interval size
of 4096 bytes.
local. Refers to one’s own system.
local area network. A data network located on the
user's premises in which serial transmission is used for
direct data communication among workstations.
local filestore. A collection of local files. Each local
filestore is registered in the LRD with a filestore nickname
for local access, and a filestore AET for remote
access.
Local Resource Directory. The file containing information
on local users, local filestores, filestore subsets,
and local files necessary for OSI/File Services to run initiator
and responder functions.
local-request handler. A server subtask that can
process a request submitted at the local system and
can initiate a conversation.
log file. A file to which a NetView FTP component
writes messages.
logical unit. In SNA, a port through which an end user
accesses an SNA network. Each NetView FTP server
is a logical unit.
logical unit name. A name used to represent the
address of a logical unit.
LRD. Local Resource Directory.
LU. Logical unit.
