Oracle Error Message
ORA-38874: cannot flashback data file string – missing incarnation information
Reason for the Error
Flashback Database failed because incarnation information for the start of the offline range for a file was not found in the control file. Flashback could not update the file’s header with the missing incarnation’s resetlogs information.
Solution
Check the trace log for the offline range of the data file. If redo logs from the missing incarnation can be found, register the logs in the control file and retry the command.
