Everytime I have duplicated a database using rman, I have duplicated the whole database. In fact, I did not know you could use rman to duplicate part of a database. But it would make sense the the duplicated database must have a complete data dictionary. But it seems that you can duplicate a database without duplicated the indexes if they are in their own tablespace, or it seems that you can duplicates one or more partitions in a partitioned table if the ones skipped are in their own tablespaces.

So unless you are doing an incomplete duplication of a database, this section doesn't matter. IMHO, doing a complete duplication of a database from a backup should be a simple thing to do.
