Sun Java System Portal Server 7 Community Sample Guide

Database Configuration

The Portal Server software creates a Java DB server instance at install time. A Java DB server instance is defined by a unique value for the Java DB system home directory. By default, the value is PortalServer-DataDir/derby. Whenever the Java DB server process is started, it must be passed the Java DB system home value by specifying the system property derby.system.home. The Java DB system home directory contains the database configuration, logs, and data files.
