node
node. In SNA, an endpoint of a link or junction common to two or more links in a network.
There are peripheral and subarea nodes. Nodes include host processors, communication
controllers, cluster controllers, and workstations. Nodes can vary in routing and other
functional capabilities.
node type (NT). A classification of SNA network nodes on the basis of the physical unit
(PU) type associated with the node. For instance, a node containing a PU of type 4 is
called a Node Type 4.
NonStop Transaction Services/MP (NonStop TS/MP). A Tandem product that provides
process management and link management functions for OLTP applications on Tandem
NonStop systems. NonStop TS/MP consists of the PATHMON process, the LINKMON
process, the PATHCOM process and interface, and the Pathsend procedures. Together
with NonStop Transaction Manager/MP (NonStop TM/MP), NonStop TS/MP forms the
foundation for Tandem’s open transaction processing services, including those provided
by the RSC and POET products, the NonStop TUXEDO system, and the Parallel
Transaction Processing Services for the CICS API (PTP) product.
NT. See node type (NT)
.
outbound data stream. A 3270 data stream that is sent from the application to the device.
page mode. The appearance, to an application or user, of the block mode of a terminal. A
page-mode application displays a whole screen of data as a unit, allowing the user to
make changes at various row and column positions before pressing a function key to
transmit the whole screen of data to the host. See also block mode
.
parameter. An argument that can be passed between procedures.
Pathway. A group of software tools for developing and monitoring OLTP applications that
use the requester/server model of application design. Requesters can be either SCREEN
COBOL programs interpreted by the terminal control process (TCP) or C, C++,
COBOL85, Pascal, or TAL programs that use the Pathsend procedure calls. Servers are
grouped into server classes to perform the requested processing. On Himalaya systems,
this group of tools is packaged as two separate products: NonStop TS/MP and
Pathway/TS. On earlier Tandem systems, the tools are packaged as a single product
called Pathway. See also NonStop Transaction Services/MP (NonStop TS/MP)
and
Pathway/TS.
Pathway application. A set of programs that perform online transaction processing tasks in
the Guardian environment, using interfaces defined by Tandem. A Pathway application
can include SCREEN COBOL requesters, Pathsend requesters, and Pathway servers
running on Tandem NonStop systems.
Pathway/TS. A Tandem product that provides tools for developing and interpreting screen
programs to support OLTP applications in the Guardian environment on Tandem
NonStop systems. Pathway/TS screen programs communicate with terminals and
intelligent devices. Pathway/TS includes the TCP, the SCREEN COBOL compiler and
run-time environment, and the SCREEN COBOL Utility Program (SCUP). It requires
