How many database backups do you have? I'd read your policy as obsoleting archive logs no longer required for your oldest level 0 backup. That is I expect having 2 backups of the db more recent than the oldest log would do the trick. The RMAN command report obsolete should help.

I tried the crossheck (even though Oracle seems to know where they are) but to no avail. This morning, I have a large number of archivelogs that have been backed up (more than once) but not purged. I tried setting the redundancy to 1 on production (to match my test database), but still "delete noprompt obsolete" does not take care of my archivelogs. However, if I say DELETE NOPROMPT ARCHIVELOG ALL BACKED UP 2 TIMES TO DEVICE TYPE DISK, it deletes them. I may have to log an SR for this one. >>It seems little obvious for me.
