To configure your Database, choose Administration -> Database -> Rename database to change the name of the database according to your requirements. During this renaming all processes in the database will be terminated (you will get a warning if processes from other host are active).
Afterwards you should adapt the address that is published by the database for access by other modules. Choose Administration -> Database -> Set published address from the menu. This will change the published address to the name of the server where your database is located and an identifier for you database, e.g. http://xy.diversityworkbench.de/Projects/ .
