Oracle Error Message
ORA-38753: Cannot flashback data file string; no flashback log data.
Reason for the Error
An attempt to perform a FLASHBACK DATABASE failed because the file does not have enough flashback log data to cover the time to flash back. Either the file did not have flashback generation enabled for it, or had flashback generation turned off for it some time during the time span of the flashback.
Solution
The file cannot be flashed back. The file must be taken offline or the tablespace dropped before continuing with the FLASHBACK DATABASE command.
