using previous duplicate file after resetlogs

Hi All,

starting with 11GR2, rman is able to optimize a duplication process, when the first attempt fail.

What i want to know is what happen in the following scenario:

1) duplicate database until scn X

a) Database will be opened with resetlogs

b) no change is made in database

2)Now, if i run the following command:

duplicate database until scn Y   -- Where X < Y

Does rman use the same previous datafile already restored by step 1)

(Ie: using previous duplicate file ...) ?

Or

rman will do the real real restore ?

Regards

Howdy, Stranger!
