Oracle : Ошибка ORA-01172

"recovery of thread %s stuck at block %s of file %s"
*Cause: Crash recovery or instance recovery could not apply a change to a
block because it was not the next change. This can happen if the
block was corrupted and then repaired during recovery.
*Action: Do a RECOVER DATAFILE for the file containing the block. If this
does not resolve the problem then restore the file from a backup
and recover it.
