Oracle Error Message
RMAN-06533: KEEP … NOLOGS option cannot be used when datafiles are fuzzy
Reason for the Error
The KEEP … NOLOGS option was specified for a backup or copy of files in a fuzzy state. This kind of backup requires archived logs for recovery, so archived logs must be kept.
Solution
Remove the KEEP … NOLOGS option or make sure the files are not in a fuzzy state and resubmit the command.
