How to delete old pre refresh/duplicate rman backups.
Every month we perform refresh of dev and QA systems from production database through rman duplicate.
During refresh we drop the old database and duplicate it from production.
We also backup this duplicated new dev/QA database for a month.
My question how to delete prerefresh database via rman .
I know how to delete old pre refresh/duplicate backups by creating a dummy database.
My question is there a query to run against the catalog to generate a report for such pre-refresh backups.
We dont drop backups during our database drop command.
Many thanks.
