RE: Starting up Oracle with "missing" datafiles

This is completely untested. I'm fairly confident this is the correct way. I may have left something out however. At the least this should get you looking in the right direction.

For each file in the tablespace(s):

alter database datafile '/path/to/filename' offline drop;

Then:
alter database open;

drop tablespace tbsp_name including contents cascade constraints;

(I would probably rebuild the controlfiles after this. This begs the question.. Why not just create a new database?)
