6.3 Understanding the Oracle Tuxedo Architecture

The following image shows an Oracle Tuxedo domain, which is the basis of the Oracle Tuxedo architecture.

A Tuxedo domain, also known as a Tuxedo application, is a business software program, built upon the Tuxedo system, that is defined and controlled by a single configuration file—the UBBCONFIG file. A Tuxedo domain consists of many system processes, one or more application client processes, one or more application server processes, and one or more computer machines connected over a network.

Other important terms and concepts that you need to know about Oracle Tuxedo before performing post-installation checks are briefly described in the following sections:

• UBBCONFIG File
• MASTER Machine
• TUXCONFIG File
• TUXCONFIG Environment Variable
• TUXDIR Environment Variable

There is no need to fully understand these terms now; rather, use the sections as a reference. As you come upon these terms during the post-installation procedures, refer back to these sections to understand exactly what these terms mean.
