Because of a power outage, instance failure has occurred. From what point in the redo log does
recovery begin and where does it end?
A.
current redo log and inactive redo log
B.
checkpoint position to end of redo log
C.
beginning of redo log to end of redo log
D.
all redo logs before the point of last commit
E.
beginning of redo log to checkpoint position
In the event of an instance failure …. applying the redo records in the redo log between the current checkpoint position and the end of the log involves processing relatively few data blocks. This means that the cache recovery phase of recovery is fairly short.
