# 3. OpenSplice Enterprise Basics

OpenSplice Enterprise is configured using an XML configuration file. In this file, the user specifies the architectural model and the OpenSplice Enterprise services that are to run when the DDS infrastructure is started.

The `OSPL_URI` environment variable refers to the specific XML configuration file that is used for the current deployment. The default value refers to the `ospl.xml` file located in the `etc/config` directory of the OpenSplice Enterprise installation. The installation directory itself can be referred to by the `OSPL_HOME` environment variable. Please see The OpenSplice Enterprise Environment for details of how to set up the OpenSplice Enterprise environment.

A number of other sample configuration files that can be used when benchmarking OpenSplice Enterprise are also provided in the `etc/config` directory.

The `OSPL_URI` variable is of the form:

  `OSPL_URI=file://$OSPL_HOME/etc/config/ospl.xml`
  `OSPL_URI=file://%OSPL_HOME%\etc\config\ospl.xml`

You can refer to the `OpenSplice_DeploymentGuide.pdf` later for more details of the `OSPL_URI` variable; for now, let us see what aspects of the OpenSplice deployment are controlled by this file.

  The OpenSplice Enterprise Launcher tool assists with the selection of the `OSPL_URI` variable. There is a Configurations menu that lists the sample configuration files that are available.

The Launcher tool

The OpenSplice Enterprise Launcher tool is also able to run the examples and performance tests that are described later in this document.
