This script is designed to run against STANDBY databases to deleted applied archives older than specific number of hours defined by the user. It maintains that un-applied archives remain un-touched.
Download the script:
https://www.dropbox.com/s/xx5o6b94rv5ps30/delete_applied_archives_on_standby.sh?dl=0
How to use the script:
e.g. Deleting applied archives older than 24 hours:
LAST_N_HOURS=24
⏩ You can use FORCE option when deleting the archives from RMAN console: [Y|N] [Default is NO]
⏩ You can decide to CROSSCHECK the archivelogs after the archivelogs deletion: [Y|N] [Default is YES]
⏩ Also you can schedule it to run periodically in the Oracle's user crontab as well.

How to use the script:
⏩ Set MAIL_LIST variable to your E-mail to receive an email alert if archives are not applied.
e.g. MAIL_LIST="john.smith@abc.com"
⏩ Specify the candidate archives for deletion older than N hours by setting LAST_N_HOURS variable to the number of hours.
e.g. MAIL_LIST="john.smith@abc.com"
⏩ Specify the candidate archives for deletion older than N hours by setting LAST_N_HOURS variable to the number of hours.
e.g. Deleting applied archives older than 24 hours:
LAST_N_HOURS=24
⏩ You can EXCLUDE any instance from having the script to run against by passing the INSTANCE_NAME you want to exclude to EXL_DB variable.
e.g. excluding orcl from archive deletion:
EXL_DB="\-MGMTDB|ASM|orcl"
⏩ You can use FORCE option when deleting the archives from RMAN console: [Y|N] [Default is NO]
e.g. FORCE_DELETION=Y
⏩ You can decide to CROSSCHECK the archivelogs after the archivelogs deletion: [Y|N] [Default is YES]
e.g. VALIDATE_ARCHIVES=Y
⏩ Also you can schedule it to run periodically in the Oracle's user crontab as well.

although all archivelogs are applied on the standby, the script returns this error:
ReplyDeleteRMAN-08120: warning: archived log not deleted, not yet applied by standby
Even I face the same bug on 12c+ versions, you can simply set the FORCE_DELETION parameter at line 65 to YES, this will forcefully delete the "APPLIED" archives and overcome this bug:
