Minimizing your software footprint contributes to a security system because you are reducing the possible areas of attack.
To reduce your software footprint, you should install only those Oracle and third-party software packages that you need to deploy your application.
The WebLogic Server installation that is recommended in the Oracle Endeca Server Installation Guide installs the minimum number of packages that are required by an Endeca Server deployment. The Choose Products and Components screen of the installer looks like this:
As the screen shot shows, only the Core Application Server, Administration Console, and Configuration Wizard are installed. Note that the Oracle Coherence product was not installed because Endeca Server does not utilize it.
In particular, you should not install the Server Examples package, which includes the Derby database used by the sample applications.
Do not run WebLogic Server when configured in development mode. Instead, make sure WebLogic Server is configured to run in production mode. Production mode sets the server to run with settings that are more secure and appropriate for a production environment.
