"resizing datafile %s failed"
*Cause: An operating system error occurred when Flashback Database tried
to shrink (resize) a datafile. Flashback shrinks a file in order
to undo the effects of a file expand, for example, an
autoextension of the file.
*Action: Recover the database to return it to its previous state, or fix
the cause of the operating system error and retry the Flashback.
If that is not possible, then the file can be taken offline and
the Flashback command retried. The file will have to be restored
from a backup and rolled forward.
