The default configuration of Nova Orchestra uses the Database
persistence service and the HSQL Database. Nova Orchestra has also been
tested with Oracle, MySQL and Postgres database system. To change to mysql, postgres or
Oracle, you need to put the corresponding JDBC driver in the directory
catalina_base/webapps/orchestra/WEB-INF/lib
and
modify the hibernate.properties
file
(see Section 4.3.4.1, “Database Access Configuration”)
