Scripts to reengineer a DB / recovery speed-up

Dear gurus !

Could you please point me to a free script /tool to capture the current DB metadata and to be able to recreate the DB (except for the actual data), i.e. tablespaces, users, roles etc...

I can think of 2 semi-ways of doing it:
1) get the physical DB attributes (data files , redo logs , character set etc..) from "alter database backup controlfile to trace" 2) get the rest of metadata from a full DB export with no rows (rows=N).

But if someone has a ready script , it will save me some time and work ;-) Thanks a lot !

Another question : i need the above in order to speed up bringing our DB back to production. We currently back it up via RMAN to tapes (via HP OmniBack II).
This is a quite large DB (~950 GB, running on win2k , no UNIX) , and the RMAN restore/recovery took almost 48 hours after the recent crash. We're looking to speed up recovery and the most feasible option seems to be this : recreate the DB (empty DB , just build the users, TBS , tables etc..) , load configuration / reference / lookup/ static data (which needs to be backed up (exported) separately) .
At this point the DB is operational again, loss of detailed data may be tolerated.

The actual question is : what do you think of this scheme ?
