RE: db file scattered read

it does not. Try it out. The blocks in a multi-block read have to be contiguous and Oracle can not guarantee that if the read would span an extent boundary. I suppose Oracle could check, but that would likely incur more overhead than you'd possibly save over issuing two scattered reads.
