Any more suggestions on the below query please.

I want to know the difference between normal and roll forward mode of

Have you read the "Normal Mode versus Roll-Forward Mode" in the
Administration Guide manual?  That section provides a good explanation

 and search on

to learn of ramifications in certain situations.
