    spreading datafiles for a tablespace

    Just wondering: Does it make a difference, performance-wise, between the following two cases?

    Case 1:
    Tablespace A with single datafile on a physical disk

    Case 2:
    Tablespace A with multiple datafiles on the SAME SINGLE physical disk

    Of course, we should spread out the datafiles as much as we can but if I only have one physical disk, does it make a difference whether I have multiple datafiles?

    Thanks,

    It makes no performance difference, but it does give you more flexibility in the future if you split the TS into multiple files. At least if you get another device available you can just move one of the files over to it.
