And if it was not the OP that imagined so, at least I did. Well, again something where I was wrong in my thinking about how Oracle internally handles things.

Does your answer imply that oracle used a full redo block as soon as a transaction changes only a byte on a db block, but never uses more than one redo block for every block on which a byte is changed.

Could you give me a pointer where I find more about this things. I find them extremly exciting.
