    No that's not true! Read the code please. The result is a simple
    wighted sum without artificial unit.

    That's only a matter for the "smooth" anglosaxons. Different
    cultures have different measures on this. I don't feel the need
    to adjust myself to the american cultural obstructivity.
    I esp. to the habit of don't saying clearly what one means if one
    want's to criticize something.

    No that isn't true. I esp. the behaviour will be predictable.

    You misunderstood me compleatly. I wasn't using an running oracle
    db as a test case. I was using the INSTALLATION process.
    Since you apparently don't know about oracle I will tell you:
    It involves a lot of different applications. Infact TONS of:
    Java, shell, compiler, linker, apache, perl and whatanot.

    I would like to state: The current heuristics DON'T serve us well
    on desktop boxes...

    That's true for sure.
