Create Required Folders 6. When you issue a RECOVER command, RMAN finds the needed restored archived logs automatically across the destinations to which they were restored, and applies them to the datafiles. To recover the standby database after the loss of one or more datafiles, you must restore the lost files to the standby database from the backup using the RMAN RESTORE DATAFILE command.
