TS/MP Pathsend and Server Programming Manual (H06.05+, J06.03+)

modified data tag
(MDT)
In SCREEN COBOL, a bit that is set or reset to indicate whether data in an associated field is to
be sent to the computer from the terminal.
multithreaded A programming model that provides more than one thread of control within a program.
Multithreading allows multiple sequential processing tasks to be executed concurrently within a
process: for example, a terminal control process (TCP). See also thread and single-threaded.
native System/T
client
In the NonStop Tuxedo environment, a client program that executes in the Open System Services
(OSS) environment and communicates directly with System/T. An example of this type of client
is the Pathway translation server for the NonStop Tuxedo system. Also called a NonStop Tuxedo
native client.
nested server A server that acts as a requester by sending requests to other servers. In the Pathway environment,
such requests are made by calls to Pathsend procedures.
nld utility A utility that collects, links, and modifies code and data blocks from one or more object files to
produce a target TNS/R native object file.
no-early-reply rule The rule that states that when a server process reads a request message, it should completely
process the request before it replies to it.
node A NonStop system that is part of an Expand network. The name of the node, also called the
system name, is the first of four parts of a file name in the Guardian environment. See also Expand
networking software.
nondedicated
device
A term formerly used for a terminal or other input/output device on which a Pathway application
could be started from PATHCOM with a RUN PROGRAM command. The RUN PROGRAM
command results in the creation of a temporary TERM object to control the terminal. (No new
term replaces this term; instead, the manual text now refers to such devices as those associated
with temporary TERM objects.) See also dedicated device and temporary TERM object.
noninteractive
mode
An operating mode in which commands are entered through a command file.
NonStop Kernel See NonStop Kernel.
NonStop Kernel The operating system for NonStop systems. The operating system does not include any application
program interfaces.
NonStop
processing
On NonStop systems, processing characterized by continued operation even when a component
fails, when equipment is being repaired or replaced, or while new processors or peripheral
devices are being added to the system. In the Guardian environment, NonStop processing is
provided by means of fault tolerance and process pairs.
NonStop SQL/MP The HP relational database management system that promotes efficient online access to large
distributed databases. See also Structured Query Language (SQL) and Enscribe database record
manager.
NonStop Tuxedo
application
The collection of machines, servers and services, and System/T components defined by a single
configuration file in the NonStop Tuxedo environment. See also NonStop Tuxedo transaction
processing environment and Pathway application.
NonStop Tuxedo
environment
See NonStop Tuxedo transaction processing environment.
NonStop Tuxedo
native client
See native System/T client.
NonStop Tuxedo
server
A server process or program managed by the NonStop Tuxedo system administrative facilities.
See also Pathway server.
NonStop Tuxedo
system
HP’s implementation of the BEA Systems, Inc., Tuxedo enterprise transaction processing system.
Major features of the NonStop Tuxedo implementation include the use of the NonStop core
services (NonStop Kernel, TS/MP, and TMF) to provide the NonStop fundamentals (scalability,
availability, and manageability) for NonStop Tuxedo applications. The NonStop Tuxedo system
runs in the OSS operating environment on NonStop systems. See also OSS environment.
NonStop Tuxedo
transaction
processing
environment
An environment that provides the API and transaction monitor functions of the BEA Systems, Inc.,
Tuxedo transaction processing system in addition to the benefits provided by the NonStop core
services: NonStop Kernel, TS/MP, and TMF. See also Pathway transaction processing environment.
