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.

Starting the application

Following all this preparation, we can boot the application by using the tmboot tool with my favorite -y option:

tmboot -y

You will see the following result:

Booting all admin and server processes in /home/oracle/code/02/tuxconfig
INFO: Oracle Tuxedo, Version 12.2.2.0.0, 64-bit, Patch Level (none)
Booting admin processes ...
exec BBL -A :
        process id=1296 ... Started.
Booting server processes ...
exec toupper.py -s TOUPPER:PY :
        process id=1297 ... Started.
2 processes started.

That's it! Our application is finally up and running and we can run our client program against it. Just run the following command:

python3 client.py

A HELLO, WORLD! message in uppercase will be printed to the console.
