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.

Chapter 12: Modernizing the Tuxedo Applications

Oracle Tuxedo is an interesting piece of software. It has benefited from years of research and development, it works in synergy with Unix-like operating systems, and it was efficient on computers less powerful than today's smartphones. I like it a lot. But it is commercial and closed source software. That alone prevents it from being used when a new software is developed.

Most new software projects rely on open source software with an active community. Sooner or later, someone from management will initiate the modernization of Tuxedo applications, which stands for replacing with cheaper alternatives in management-speak.

In this chapter, we will attempt to replace parts of a Tuxedo application by covering the following topics:

  • Introducing NATS
  • Developing a basic NATS application
  • Developing a bi-directional gateway

By the end of this chapter, you will know about NATS and why it is a good fit for modernizing...
