NETNAME
In CICS, the name by which a CICS terminal or a CICS system is known to VTAM.
NETPARS
See object module.
NetView
A network management product that can provide automated operations and rapid notification of events.
NetView Performance Monitor (NPM)
An IBM licensed program that collects, monitors, analyzes, and displays data relevant to the performance of a VTAM telecommunication network. It runs as an online VTAM application program.
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.
