naku telisi, Point in time recovery lekunda nuvvu recent ga delete chesina table ni recover cheyalevu..

1. if running in arc log mode, PIT recovery avuddi, but thats not like restoring one datafile, it restores and recovers all the DBF's
2. no arc log mode aite, last tesina backup ke u can recover/restore

NO.. PIT cheyakunda you cannot restore to its previous state before you have deleted the table.... all you can do, is, from existing backups, you can restore to tht backup time, but not PIT

nuv sql command use chesi drop chesthe, control file lo update avthundhi kadha aa datafile drop aipoyinattu...so unless PIT(to before dropping that datafile) recover chesthe thappa aa datafile recover kaadhu

nuv rm command use chesi delete chesthe control file lo update kaadhu, so rman still assumes that datafile should exist and recovers it.
