### 3.3.2. Database Management

The default configuration of Orchestra uses the Database persistence service and the H2 Database. Orchestra has also been tested with Oracle, MySQL and Postgres database system. To change to mysql, postgres or Oracle, you need to install the corresponding JDBC driver bundle in the OSGI platform and modify the `hibernate.properties` file (see Section 4.3.4.1, “Database Access Configuration”)
