I don't know what they paid, but just recovering some files off a Windows software raid... a few thousand dollars? Once Oracle DUL gets involved, we're talking tens of thousands of dollars, arent' we? I don't disagree with you or Sybrand, the OP just needs to know options. Maybe they have enough to do something without DUL. Then again, there's some Polish place where you just upload your data files there... and some guy in China... yeesh.

I find the "we lost our db" posts highly entertaining, and sometimes even educational. Backups are the most basic thing! Recovery is the Only Thing!

To Paulo: Sybrand gave you a clue, you might be able to use your new db to generate an editable controlfile (alter database backup controlfile to trace;), then you might be able to edit it to use all your recovered files. Or not. But you can't use the dbid changing utility with those screwy datafiles, so don't bother trying to use the new db with the old data.
