RMAN-06107: WARNING: controlfile is not current for REPORT NEED BACKUP DAYS
Cause: The REPORT NEED BACKUP DAYS command may report some files as requiring backups when they really do not, because the most current online status of the file is not known unless a current control file is mounted.
Action: No action required, however, a current control file should be mounted, if possible, to get the most accurate REPORT output.
