- network
- (1) An interconnected group of nodes among which information
is passed.
- (2) The collection of equipment through which connections
are made between nodes.
- network address
- In SNA networking, an address that consists of subarea and element fields
and identifies a link, link station, or network addressable unit. Subarea
nodes use network addresses; peripheral nodes use local addresses. The boundary
function in the subarea node to which peripheral nodes are attached transforms
local addresses to network addresses and network addresses to local addresses.
See also network addressable unit (NAU).
- network addressable
unit (NAU)
- In SNA networking, any device on the network that has
a network address, including logical units, physical units, and system services
control points.
- network configuration
- In SNA,
the group of links, nodes, machine features, devices, and programs that make
up a data processing system, a network, or a communication system.
- network control program (NCP)
- A program that controls the operation
of a communication controller.
- network job entry (NJE)
- In CICS/VSE only, a facility for transmitting jobs (JCL and in-stream
data sets), SYSOUT data sets, (job-oriented) operator commands and operator
messages, and job accounting information from one computing system to another.
A facility that provides access to batch computing facilities from other host
systems. It enables users to transfer work and data throughout a distributed
network of batch computing facilities. (NJE is not a part of Systems Network
Architecture (SNA), but is an application layer that uses SNA, BSC and CTC
transmission facilities.) In CICS Transaction Server only, the implementation
of the NJE protocol in the JES2 licensed program.
- Network Logic Data Manager (NLDM)
- A program that collects and
interprets records of errors detected in a network and suggests possible solutions.
NLDM consists of commands and data services processors that comprise the Netview
software monitor component.
- network name
- In SNA,
the symbolic identifier by which end users refer to a network addressable unit (NAU) (NAU),
link station or link. In APPN networks, network names are also used for routing
purposes. See also network address.
- Network Performance Analysis and Reporting System (NETPARS)
- An
IBM licensed program that analyzes network log data from the NetView Performance
Monitor (NPM).
- Network Problem Determination Application (NPDA)
- A program that
collects and interprets records of errors detected in a network and suggests
possible solutions. NPDA consists of commands and data services processors
that comprise the Netview hardware monitor component.
- NJE
- See network job entry (NJE).
- NLDM
- See Network Logic Data Manager (NLDM).
- NLS
- See national language support (NLS).
- NLT
- See nucleus load table (NLT).
- node
- (1) In communications, an end point of a communications link, or a junction common
to two or more links in a network. Nodes can be processors, communication
controllers, cluster controllers, terminals, or workstations. Nodes can vary
in routing and other functional capabilities.
- (2) In a network, a
point at which one or more functional units connect channels or data circuits.
In general, a node has the capability to recognize and process or forward
transmissions to other nodes.
- (3) In FEPI. a point (VTAM nodes) that
is a secondary LU terminal simulated by FEPI.
- node
abnormal condition program (NACP)
- A CICS program used by terminal
control to analyze terminal abnormal conditions that are logical unit or node
errors detected by VTAM.
- node error block (NEB)
- A set
of recording areas of the node error table used to count node errors relating
to a single logical unit.
- node error program (NEP)
- A user-replaceable program used to allow user-dependent processing whenever
a communication error is reported to CICS
- node error table (NET)
- Table used by the node error program.
- nonconversational
- A mode of CICS operation in which resources are allocated, used,
and released immediately on completion of the task.
- noncumulative
mapping
- A form of BMS output mapping, in which each SEND MAP command
generates a device-dependent data stream for output to the terminal device,
unless PAGING or SET options are specified.
- non-response mode
- In IMS, a mode of terminal operation that allows asynchronous operations between
the terminal operator and the application program. Contrast with response mode.
- nonshared resources (NSR)
- Files with their own set of buffers
and control blocks. See also local shared resources (LSR).
- nonswitched
connection
- A connection that does not have to be established
by dialing. See also switched connection.
- nonswitched line
- A telecommunication connection that does not have to be established by dialing.
- nonyielding loop
- A type of loop in which control is returned temporarily
from the program to CICS. However, the CICS routines that are invoked are
ones that can neither suspend the program, nor pass control to the dispatcher.
There is, therefore, no point at which the task can be suspended.
- no response
- In SNA, a value in the form-of-response-requested field of the
request header that directs the receiver of the request not to return any
response, regardless of whether or not the request is received and processed
successfully. See also definite response (DR), exception response (EX, ER).
- NPDA
- See Network Problem Determination Application (NPDA).
- NPM
- See NetView Performance Monitor (NPM).
- NSR
- See nonshared resources (NSR).
- nucleus
- That portion of the CICS region that holds the CSA, management
modules, control tables, and resident application programs.
- nucleus
load table (NLT)
- A table that enables you to utilize virtual storage
efficiently, by creating a load order that provides the smallest possible
working set. The table is used by CICS to control the load order of the CICS
nucleus. It allows you the option of changing the default load order established
by the CICS system initialization program.
