Just follow the following step. very simple

1. alter database datafile 'missing file' offline drop;
2. Shutdown your database
3. add a parameter _corrupted_rollback_segments = (<rollback segment

name that exists in the missing datafile tablespace>) in your init.ora 4. remove the rollback segment name from rollback_segments paramter in init.ora
5. Startup your database in open mode
6. drop tablespace <the tablespace> including contents; that is. remember to remove _corrupted_rollback_segments from you init.ora after that.
