If no release number is specified, the most recent version is invoked. Ensure that
application developers are told which version of the Pathmaker software they should
use.
Refer to the Utilities section of the Pathmaker Reference Manual for details about using
the PMINSTAL utility to install more than one version of the Pathmaker software.
One of the Enform queries provided with the Pathmaker product can be used to
produce a report that lists all of the Pathmaker versions found on a system. Refer to
the Project Catalog section of the Pathmaker Reference Manual for information about this
query.
Note The Pathmaker product, versions 1 and 2, are not supported on D20 systems. You must convert all
projects to Release 3 of the Pathmaker product if you are running D20 Tandem software. Versions 1 and
2 will continue to be supported on their previous releases until Tandem discontinues support for the
release as a whole.
Using Pathmaker for
Client/Transaction
Server Application
Development
If you are creating client/transaction server applications for a Tandem system, you can
use the Pathmaker product to create the servers for the application. The clients for the
application can be created manually or with a number of products.
A Tandem product that can be used to create clients is the Pathway Open
Environment Toolkit (POET). POET is a set of programs and utilities that enable you
to create clients and run client/transaction server applications on a Tandem system.
The C31 version and D20 versions of the Pathmaker product have been enhanced to
work in conjunction with POET; however, you do not need POET to use the
Pathmaker product.
If you are using the Pathmaker product in conjunction with POET, you are mainly
interested in the portions of the Pathmaker product used to:
Define the application data (see “Defining Data for a Pathmaker Project” in
Section 2)
Create services and servers (see Section 4)
Define the IPC messages (see Section 4)
Supply application configuration information (see Section 7)
Consult the Pathway Open Environment Toolkit (POET) Programming Manual for more
information about using the Pathmaker product with POET.
