=== Changing the Database ===

To change the database used by gnuMims a custom WAR must be built from the source code.

Most common databases are supported by Grails (via Hibernate), we test and run MySQL (InnoDB).[[BR]]
The database must support transactions and row locking.[[BR]]
The data source can be configured in the grails-app/conf/DataSource.groovy file.[[BR]]
A jar matching the configuration needs to be placed in the projects lib dir (e.g. lib/mysql-connector-java-5.1.7-bin.jar [http://dev.mysql.com/downloads/connector/j/5.1.html Connector])
