BerklyDB is not a relational database like MySQL, it has not centralized server. It's not something you log into and administer.
It's a database realized in library format; the data is stored in simple key=>value pairs and is specific to the application. The application links to the BerklyDB library and makes library calls to store data.
I would look for a .db file somewhere in the applications directory structure.
BerklyDB is a product of
Sleepycat software.
