Hi. I restarted the server after the web service hang up. When the server booted one of my databases "named bk" stopped functioning. I went to the svrmgrl and, when i try to start the database, it says that one of the files is Corrrupted!!! (Error ORA-01251)

Is there a solution for this? I have not a backup (it's a test database anyway, but it will bother me having to copy it again. The real database is in another establisment).

Is this very common? that suddendly the database destroys itself?
