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.

Exposing Tuxedo services as web services

The Workstation client API is limited to programming languages that provide bindings for Tuxedo libraries. But not everyone wants to learn a new paradigm and API just to interact with a Tuxedo application, although this book attempts to teach it. Most developers are familiar with the HTTP protocol and XML or JSON data formats used by web services.

There are several solutions to expose Tuxedo services as web services:

  • Oracle Tuxedo offers a paid add-on called Oracle SALT that enables you to expose Tuxedo services as web services with a SOAP, XML, JSON, and HTML payload and call web services from the Tuxedo application. This add-on is attractive if your tool is the C programming language without standard libraries for high-level network programming. With Python, you have plenty of libraries and Stack Overflow at your service.
  • Another solution is to use Flask, FastAPI, or any other Python framework to develop the API, and provide...
