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.

Using the Tuxedo Workstation client

Throughout the chapters so far, we have used the Tuxedo XATMI API for developing clients and accessing the application running on the same machine. But what if we need to access the Tuxedo application from a different machine over the network? The answer to that is the Workstation component that Tuxedo offers out of the box. The main benefit is that you can develop remote clients using the same API as local (native) clients and you have access to the same features including calling any service, starting and finishing transactions.

Let's see how this works with a simple application and an ubbconfig file with the following content:

*RESOURCES
MASTER tuxapp
MODEL SHM
IPCKEY 32769
*MACHINES
"15c365dcb562" LMID=tuxapp
    TUXCONFIG="/home/oracle/code/10/tuxconfig"
    TUXDIR="/home/oracle/tuxhome/tuxedo12.2.2.0.0"
    APPDIR="/home/oracle/code/10...
