Oracle Error Message
RMAN-06133: recovery catalog may have obsolete data for datafile string
Reason for the Error
A RESTORE UNTIL was issued, and the recovery catalog choose an older incarnation of the datafile than is listed in the control file.
Solution
If the recovery catalog has correct data for the datafile, then restore a backup control file using the same UNTIL clause, then retry the datafile restore. Otherwise, restore a backup of the incarnation of the datafile listed in the control file.
