PATHMON Object
The PATHMON object is a template for configuring PATHMON processes, each of
which controls a set of requester-related and server-related objects in a Pathway/XM
environment. The objects controlled by a PATHMON process include terminal control
processes (TCPs), TERM objects, PROGRAM objects, and SERVER objects.
A Pathway/XM environment includes one or more PATHMON processes, all of which
have the same configuration attributes.
PLAN Objects
PLAN objects define a set of objects to be added, deleted, or modified while the
Pathway/XM environment is active, as part of a migration from one configuration to
another. PLAN objects are created by the INVENTORY configuration statement.
TCP Templates
In the Pathway/XM environment, you define the attributes of your TCP processes
(TCPs) by means of a TCP template, which provides a set of attribute values to be
applied to multiple TCPs. You do not configure individual TCPs explicitly. Instead,
PXMCFG automatically calculates the number of TCPs needed to support the requester-
related objects in your configuration, and then adds those TCPs to your configuration.
TERM and PROGRAM Objects
TERM objects represent terminal tasks controlling the input-output devices and
processes that allow users to interact directly or programmatically with a Pathway
application. Each task runs as a thread within a TCP; a TCP can handle many such
threads concurrently. There are two types of these objects: configured TERM objects
and temporary TERM objects.
Configured TERM objects are those you define and add to the Pathway/XM
configuration with PXMCFG statements. Temporary TERM objects are created for you
(and automatically deleted) at run time in response to a PXMCOM RUN PROGRAM
command.
A PROGRAM object is a template you configure to identify a particular SCREEN
COBOL program. It provides a mechanism for creating temporary TERM objects as
they are needed.
ROUTER Objects
A ROUTER object supports Compaq NonStop™ Pathway/iTS web clients. It defines the
listener process that waits for connection requests from web clients and distributes those
requests to the resources that support accepted connections (TCP processes and
terminals, for example).
