Oracle Error Message
RMAN-06095: a backup control file must be restored to recover datafile string
Reason for the Error
The control file currently mounted by the target database contains a newer incarnation of the datafile than the recovery catalog indicates is appropriate for the Point-in-Time being recovered to.
Solution
Restore the control file, using the same UNTIL clause specified on the failing RECOVER command, then reissue the command. If no control file can be restored, then you should issue a CREATE CONTROLFILE command.
