RMAN-06025: no backup of archived log for thread X with sequence Y and starting SCN of Z found to restore

"Restore validate" command could be used to determine if the backups are intact and could be used for a restore operation without any issue. The command could be used to validate database restore as well as archive log restore.
During archivelog restore it is possible to encounter errors such as below

RMAN> restore archivelog all validate;

The reason for this error is that "archive all" try to validate restore of all archivelogs and doesn't consider the retention policy.



Solution for this is to restore archivelog within the retention period. In this case retention period was

RMAN> show all;
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 2 DAYS;

Use the retention period in the validate command as

RMAN>  restore archivelog from time='sysdate - 2' validate;
