hello, i'd like to use rman to take cold and hot backups of a RAC database. how should i register the database in the rman catalog? do i register each instance of the RAC or just one instance and back that up? also, does anyone have any notes on how to successfully enable archive logging in a RAC database? i know i should know the answer to this, but i'm drawing a blank at the moment.... thanks in advance, haroon -- //www.freelists.org/webpage/oracle-l
