Is the crosscheck command suppose to be able to clear
catalog entries that are on tape? If so, can somebody
explain why I still have entries for 11/14/2011 13:28:32
when the current date is 11/16/2011 11:17:45 and I
have a retenion policy of 1 day?

Or if my crosscheck script is incorrect can somebody suggest
a fix...

This is a test system where I am testing backup to tape... I
currently disabled the backup to tape and now backing up to
disk.

RMAN configuration parameters for database with db_unique_name OTAPDEV are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 1 DAYS;
CONFIGURE BACKUP OPTIMIZATION OFF;
CONFIGURE DEFAULT DEVICE TYPE TO 'SBT_TAPE';
CONFIGURE CONTROLFILE AUTOBACKUP ON;

Hi - if you have only one backup, RMAN will not consider it obsolete until you have taken another. Then, because your recovery window is set to one day, you will have to wait another day before RMAN will consider the earlier one to be obsolete.

To follow up With a 'RETENTION POLICY TO RECOVERY WINDOW OF 1 DAYS', rman will keep at least one backup that is older than 'SYSDATE-1' at the time the 'DELETE NOPROMPT OBSOLETE;' is executed. Later on in the day (past sysdate-1) I ran the
DELETE NOPROMPT OBSOLETE and that left me with only 2 backups
as per John's explantion above.

Thx for everybody's input...
