RMAN : RMAN-08137: WARNING: archived log not deleted needed for standby or upstream capture process archived log file

Scenario Preview : 

Recently we find some error using rman backup as we are unable to delete archivelog. Although backup was successful but archivelog not deleting at there end. Reason was physical standby database was not sync and archivelog not applied at  DR  site.

Even in primary database  rman setting is set to CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default

Solution:

We forcefully deleted archivelog so NO error found at the next rman scheduled backup.

delete noprompt force archivelog all;

Error in rman backup log :
