Database Software

I've searched the forums, but am still not sure what action to take on this. Please see the error in my output, below -- why am I getting this, and is it actually preventing the "cleanup" of my archivelog files?

HERE'S WHAT I ENTERED AS RMAN COMMANDS:

RMAN> CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT 'd:\DB-BackupS\RMAN\%d_%T-%s.rbk';
RMAN> CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'd:\DB-BackupS\RMAN\%d_%F';
RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 4 DAYS;
RMAN> CONFIGURE BACKUP OPTIMIZATION ON;
RMAN> backup database;
RMAN> delete force noprompt obsolete recovery window of 4 days;
RMAN> delete force noprompt copy of archivelog all completed before 'sysdate-4';
RMAN> crosscheck backup;
RMAN> crosscheck archivelog all;
RMAN> exit


HERE'S THE RESULTS:
