Re: Windows 2003 Server v/s Unix OS for EBusiness R12

Here's my thing... When I ask them "Why do you want to do Windows?",
every site I've ever
talked to that says they want to do E-Business Suite on Windows gives
me one of three answers:

1)  Cheap(er) hardware than Unix (Sun/HP/IBM, et. al).

   While this is (somewhat) true, consider these points:

   a)   When dealing with Symmetric Multi-Processing systems (SMP),
how well a system
        "scales" is judged not only by how many processors you can
cram into it, but by how
        "linear" that scalability is.  Not only does the Intel (X86)
architecture not grow to a very
         large number of processors (biggest I'm aware of without
going NUMA is 4 (quad-core)
        CPUs... so, 16 cores).  But the CISC (Intel) architecture is
also not as linear as RISC.
        The idea being that, if you have 16 CPUs in a box, you should
be as close as possible
        to 16 times the horsepower of a single CPU...  With RISC it's
very close to linear.  With
        the x86 architecture, it starts to "veer off" somewhere
between 2 and 4 cores... there are
        a number of factors involved here (bandwidth between CPU and
memory, CPU and I/O,
        CPU-to-CPU, caching, etc.) Personally, I think AMD's
architecture scales better than Intel's
        (and from an OS standpoint, you don't really have to do
anything different...) Now, this scale
        may not matter to alot of shops, but also consider that the
pricing on the RISC boxes is
        down quite a bit in recent years...  Also, see my RAC comments
in an earlier post.

        You could also consider the cost of a "split-tier"
configuration (where the DB lives on Unix
        [sun, hp, ibm] and the appsTier lives on Linux.  You get the
cheap hardware where it counts.
       You get SMP scalability where it counts.  And, you aren't
paying extra Oracle RDBMS licenses
        because your DB box is ONLY running the DB.

    b)  Linux runs on the same hardware.

2)  "Our people know Windows, not Unix".

     This may also be true, however, consider:

    a)  The vast majority of Oracle E-Business Suite shops are running
on some flavor of Unix
         or Linux.   Therefore, those shops are more likely to
encounter a problem before you do.

    b)  Looking at:
http://download.oracle.com/docs/cd/B40089_10/current/acrobat/120oaig.pdf
        (Page 24 of the PDF file states that you will need to install
the following:)

        Microsoft Windows:  Microsoft C++, MKS Toolkit *, GNU make

        Most importantly is item #2:  "MKS Toolkit" (the * indicates
that cygwin will work too, but
        is not "recommended").  MKS Toolkit basically brings Unix
commands to Windows.  So,
        for those out there wanting to go Windows so that their
"support staff" (which will end up
        being the DBAs and NOT the help desk, by the way) doesn't have
to learn Unix, congrats!
        Now you have to know BOTH!  Plus, you have the added benefit
of dealing with some of the
        idiosyncrasies of Windows!

        Also consider that any E-Business Suite DBAs you're likely to
hire (now or in the future) are
        probably going to be more comfortable/familiar with Unix than
Windows for this product.

  3)  "The CEO/CIO/CTO/somebody important sat next to Bill Gates on a
plane and he said..."

        My response:  Bill Gates doesn't fly commercial.

My $0.16 (after taxes).
