This is more of a general knowledge question than for any particular business requirement I currently have.
Been thinking lately about optimizer statistics after duplicating a database via RMAN.
After completing the duplicate, is it necessary to regather stats for the database?
My gut feeling is no, but I've been digging through the Documentation this morning and haven't found anything specific on it, and Mr Google hasn't been able to find me anything concrete on it either.
Anyone with any specific insights on this (and references to docs would be nice to have too if you have them).
