Chris,
 Good luck on the testing of the "new" feature that you heard about. But I think that there needs to be some clarification stated about the "archivelogs". IF you have ALL of the archivelogs that ever did anything with the tables in the datafile that you delete ( I mean everything from creation to datafile delete time) then I think that you should be able to recreate the tables in the datafile with the archivelogs. If you only have the updates or inserts for the tables then how are you going to recreate all of the data and co a complete restore?
 What archivelogs are you going to test with. The logs from yesterday after a backup or logs from 2 weeks ago?
 I think that what you heard is not what they ment. If all you need to recreate a datafile is the controll file and archivelogs then the backups of today could be history. Why backup 70+ GIG of datafiles if I only have to retain my 2 MEG of archivelogs.
Please post your tests and results.

I don't know much about this feature, but someone mentioned in 8.1.7 you can recover a datafile even without a backup as long as you have a control file that knew about it and the archive logs.

Anyone give this a try? I am going to attempt this weekend on my test box.
