Title: Chapter 17 Performing Database Recovery
Course: RITA MC - ORACLE ADMINISTRATION I > Section: Unit 4 - Database Administration I

The terms restore and recover have precise meanings in the Oracle environment. To
restore a file is to extract it from a backup and return it to the place where it was
made. If a datafile is damaged or missing, a restore operation will replace it with a copy
from the backup. So far so good, but the restored file will be out of date compared to the rest of
the database. To recover the file, extract the relevant change vectors from the redo log stream and
apply them to bring the file forward in time until it is synchronized with the rest of the database.
