Introduction to Pathway Application Programming

Client/Server Development Tools
•
Automatically generating TMF statements in your requester programs when you
indicate that you want your programs to have TMF protection
•
Providing a central location for most application information
•
Creating error-handling code for the most commonly encountered errors
•
Letting you simulate application screens and navigate from one application screen to
another before you write a single line of code
Applications developed with the Pathmaker product can access data from databases
managed by either the NonStop SQL/MP relational database management system or the
Enscribe database record manager. If you are using Pathsend requesters, or clients that
use RSC or POET, you can use the Pathmaker tool to create prototype servers.
Client/Server Development Tools
As mentioned earlier, the Remote Server Call (RSC) product facilitates client/server
computing, allowing workstation applications to access Pathway servers. A large
number of packaged tools and utilities are commercially available for use with RSC,
including Tandem’s Pathway Open Environment Toolkit (POET).
Transaction Processing Scenario
Figure 1-2 and the description that follows it provide an example of how transactions
from Pathsend requesters are processed. The figure shows the path of transactions from
an IBM system to a server class on a Tandem NonStop system.
Note. The figure does not reflect the actual flow of data from the Pathsend requester to the
Pathway server class. Only server-class control information is passed to the LINKMON
process; the application data moves directly from the Pathsend process to the server class.
