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 3: Tuxedo in Detail

There are a couple of Tuxedo's implementation details that it is useful to know when it comes to making the correct technical decisions. One of them is the BBL process present in all Tuxedo applications, and the other is the use of Unix System V IPC queues. Monitoring and sizing Tuxedo's queues is one of the most important tasks for the administrator of a Tuxedo application.

In this chapter, we will cover the following topics:

  • Learning what BBL is
  • Understanding queues
  • Introducing services and load balancing

By the end of this chapter, you will have practical experience of how BBL contributes to application availability. You will understand the relationship between queues and services and the ways in which that can be expressed in the Tuxedo configuration and how load balancing works. You will also know how to get information about queue size and how to change it.
