Thank you, but, this is my main question: I never read that before in the Oracle documentation! Is it correct that RMAN utility can use Data Pump Workers??! I know That RMAN must access to V$ and GV$ views to extract some information useful for backup process BUT, is RMAN using Data Pump Workers for that?
