this is the script i am using:

LIST BACKUP;


RMAN> report obsolete;

RMAN retention policy will be applied to the command
RMAN retention policy is set to recovery window of 7 days
no obsolete backups found


this is part of the backup i have in the disk:
-rw-r----- 1 oracle oinstall 767M Sep 2 18:57 OCTL_9jko8k09_307_1
-rw-r----- 1 oracle oinstall 180M Sep 2 18:58 OCTL_9kko8k09_308_1
-rw-r----- 1 oracle oinstall 667M Sep 3 18:58 OCTL_9nkob8cn_311_1
-rw-r----- 1 oracle oinstall 201M Sep 3 18:59 OCTL_9okob8cn_312_1

-rw-r----- 1 oracle oinstall 185M Sep 4 18:57 OCTL_9skodsof_316_1

I was expecting RMAN to delete at least the backup from Sep 2:


from the log file i have from yesterday, this is what RMAN delete:
