Using this query to determine if block change tracking is being used for the backup. Change the RMAN owner, date and time, and db_id to match your environment:
Replace the completion_time accordingly in the below query
round((blocks_read/datafile_blocks) * 100,2) "%READ",
blocks WRTN, round((blocks/datafile_blocks)*100,2) "%WRTN"
where completion_time between
to_date('08-10-2010 09:00:00', 'MM-DD-YYYY HH24:MI:SS') and
