The server installer comes with support for the Hypersonic embedded database. Currently, we install the HSQL 2.5.2 database. This in-memory database is perfect for trials where you want to get up-and-running as easily as possible. This database performs automatic daily backups. There is no need to use SQL Server, Oracle or MySQL unless you have specific needs.
Using this database requires no configuration. When the server installer asks for the database type, simply select Embedded.
If you find that the embedded database is not going to fit your needs, the standard database migration technique works with all databases, so it is possible to move all your data from the embedded database into a real database at any time. In addition to using the database migration technique, to move to a real database, you will also need to reconfigure the Collaborator server by running the Server Installation program.
