Friends & Gurus:

Is there a way to drop a database? I have 4 databases that I no longer need and want to drop them to free up some disk space. I have already taken backup of them just in case. The only way i know is to drop the tablespaces w/in the database, but ran into some problem. Unable to drop the 'system' and 'rbs' tablespace. Any help/advice would be much appreciated.
