Overview of Configuring and Managing
Pathway/XM
This section describes the processes and basic operation of a Compaq NonStop™
Pathway/XM environment and introduces the tasks you perform to manage a
Pathway/XM environment.
The following topics are included:
Configuring a Pathway/XM Environment
The Pathway/XM product provides a set of processes and tools that enable your business
to configure and manage Pathway online transaction processing (OLTP) applications.
Such applications consist of two types of processes:
•
A requester (also called a client) processes transaction requests from users and sends
requests to a server process.
•
A server provides informational and processing services to requesters.
The various elements of the Pathway/XM environment are designed to manage these
two types of processes and the communication between them.
To configure and manage a Pathway/XM environment, you use two separate utility
programs:
•
PXMCFG, a batch-type utility that configures your Pathway/XM environment
•
PXMCOM, an interactive utility that manages your application online
Building a Pathway/XM Configuration
All objects in a Pathway/XM environment are administered through a single control file,
called the SuperCTL file. To set up a Pathway/XM environment, you first write a file
that contains the configuration statements that define your operational environment. You
can do this either by entering the configuration statements into a text file, or you can use
the Pathway/XM Analyst tool on your workstation to interactively create a configuration
and generate a configuration source file, which you upload to the NonStop™ Himalaya
system. See Pathway/XM Analyst Configuration Tool
in this section.
