Rick - Does this query find the blocks used since the last RMAN backup? Or
some other criteria like since the instance was started?

Hi
As we all know RMAN backs up only the used blocks in the database.Was
wondering if there is any way to query the database to find out if a block
is used or not so as to find out how much of the database is currently
being used ?
TIA
