RMAN-08138: WARNING: archived log not deleted - must create more backups

when i tried to delete archivelog older than 7 days. i faced below error. because i didnt took any backup of archive logs.  to avoid this type of such issue, it is better you take full backup.

RMAN> delete archivelog until time 'sysdate - 7';

Solution:

to resolve this issue, we have to force delete all archivelog using below command.


RMAN> delete noprompt force archivelog until time 'sysdate - 7';


all archivelog files older than 7 days get deleted.
