Oracle Differences Between Crash Recovery And Media Recovery

Today I has assited to a workshop about Rman 12c. We started introducing to ours, there were persons with very differents skills and experience but when the teacher ask us about the differences of Crash Recovery from Media Recovery, many people don’t know what it is. I like remember what every one is.

Crash Recovery, is the automatic (no manual action is needed) recovery, a tipical case is where a power outage occurs, in the next start up Oracle perform the work.

Media Recovery, is the manual recovery (restore and recover), a typical case is when a datafile is lost. You need restore the damaged datafile and apply the archived redo over the datafile.
