You have determined that one of the data files
belonging to the SYSTEM tablespace is corrupt.
Which complete media recovery scenario do you
choose?
A. Complete recovery – mounted database.
B. Complete recovery – opened database,
initially opened.
C. Complete recovery – opened database,
initially closed.
D. You cannot recover from the corruption of
a database file belonging to the SYSTEM
tablespace except by going back to the last
full backup.
我觉得应选D,可有人说A,我有点晕了。
