Recovery internals

Hi All,

This is M. Ramesh Kumar. I have a doubt. What different steps (internal steps) Oracle performs when performing recovery?

My expectation for the question is not like it performs redo roll forward and roll backward.

I am expecting what activities it does to go with roll forward and roll backward?

Scenario: I have a database of size 5 TB. I have last week full backup. I have lost a data file.

Here we can restore the datafile from the last week's backup and recover the datafile. Here how it proceeds with the roll backward and roll forward?

Awaiting your reply.....
