It shouldn't do anything special to your broker ... You can also try setting dataDirectory to the <amq:broker> element.
Anyhow, since you are using relational database for the storage, are you sure you're starting your broker with a clean database (in case you are not using Derby)? If you are using Derby, databaseName property is actually a folder name where the database is created.
