Types of Database Failures
If some datafiles are damaged during a disk failure, but most of the database is
intact and operational, the database can remain open while the required tablespaces
are individually recovered. Therefore, undamaged portions of a database are available
for normal use while damaged portions are being recovered. This is a very desirable
feature, especially for large corporate databases that must be up and running “twenty
four by seven.”
