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 9: Working with Oracle Database

These days it is hard to find an application that does not use a database for persistence. It might be a relational database, graph database, NoSQL database, or even an SQLite database on your mobile phone. Tuxedo applications are no different. While many databases can be used with Tuxedo, its best friend is the Oracle Database. Tuxedo is optimized for working with the Oracle Database. Even the transaction log we learned about in Chapter 7, Distributed Transactions, can be stored inside the Oracle Database instead of a file.

You will need an Oracle Database for this chapter. You may use the one you have already or use a Docker image available from the Docker Hub at https://hub.docker.com/_/oracle-database-enterprise-edition. Getting access to the Oracle Database is your homework before reading the chapter, as also mentioned in the sections ahead.

In this chapter, we will cover the following topics:

  • Preparing the database
  • Using...
