I might not have been clear in describing WHY I want to know more about
this, but in fact I won't touch a running system, not in the way one can
initially understand it. Let me explain better:
My company has acquired another company and thinks about concentrating
dbs and applications on our machines to eliminate machines on their side
to save money from technical support contract. They have db on file system
and when we transport it onto our site (after two or three test rounds) I
thought to take the chance and put it onto raw device. All our dbs are on
raw device, so why should I have one on file system (yeah, to make
comparisons ...)?

I guess you are right.

Yeah, for the hardware I agree. But you have to have someone to ask if
something does not work, right? That's what support contracts are for,
right? And, as I said in another post, IBM (or other big ones) might not
be all brilliant but at least have large issue dbs and many people and
resources. One of them, at least one of them, might have had the same
problem already, right? AND, you have someone to blame ... ;-)

No, it's not free at last. Support costs $$$, probably less than IBM, but
I guess there will be less in return ... If my IBM does not run because of
bug xyz or problem I suppose in one, two, three days there will be at
least a workaround. With SLES? How many days of billing will fade away,
how many new contracts lost before SLES comes out with at least a
workaround?

Thanks a lot and have a nice day,
