Oracle Solution for Error ora-16133

ORA-16133: Datafile string has incorrect terminal recovery stamp.

What triggered the Error:

After activation of a standby database following a terminal recovery (recovery of standby using current logs), recovery of a datafile from before the activation must have completed the same terminal recovery to avoid corruption.

What should we do to fix it:

A backup of the datafile taken after the terminal recovery and before activating the standby must be used for recovery.
