Modernizing Oracle Tuxedo Applications with Python

By: Aivars Kalvans

Overview of this book

Despite being developed in the 1980s, Oracle Tuxedo still runs a significant part of critical infrastructure and is not going away any time soon. Modernizing Oracle Tuxedo Applications with Python will help you get to grips with the most important Tuxedo concepts by writing Python code. The book starts with an introduction to Oracle Tuxedo and guides you in installing its latest version and Python bindings for Tuxedo on Linux. You'll then learn how to build your first server and client, configure Tuxedo, and start running an application. As you advance, you'll understand load balancing and work with the BBL server, which is at the heart of a Tuxedo application. This Tuxedo book will also cover Boolean expressions and different ways to export Tuxedo buffers for storage and transmission, before showing you how to implement servers and clients and use the management information base to change the configuration dynamically. Once you've learned how to configure Tuxedo for transactions and control them in application code, you'll discover how to use the store-and-forward functionality to reach destinations and use an Oracle database from a Tuxedo application. By the end of this Oracle Tuxedo book, you'll be able to perform common Tuxedo programming tasks with Python and integrate Tuxedo applications with other parts of modern infrastructure.

Summary

In this chapter, we learned about different message types that Tuxedo supports and how to use them from Python. We spent a lot of time on the best and most common message type supported by Tuxedo – FML32. We learned how to call services without writing any code, and investigated different features and quirks you should be aware of when using FML32. We even built a clone of the Tuxedo native ud32 tool using just a few lines of Python. And finally, we learned how to persist Tuxedo messages in a standard way.

We have learned enough information about messages exchanged in Tuxedo for the rest of the book, and now it is time, in the next chapter, to learn more details about sending these messages between clients and servers.
