Rafiq,
As I'm working in one of the premier (top 10) trials companies to
the pharma community we are moving all our databases/applications off of
Windows for Unix based operating systems. These are validated, no
problem. Windows has two basic problems, memory and processes. Without
a start up switch your limited to 3GB total memory for Oracle, with the
switch you can have another gb, but it uses memory context switches
which are a performance killer. The second is that Oracle on Windows is
multithreaded within a single executable where as Unix based systems
have multiple processes again limiting capacity. Our windows based
databases are a real pain in the shorts, they are constantly hitting
that "blue screen of death" at least once a week. As it is after 1 June
we will no longer support or validate a Windows database.

Robert,
I don't agree that Window is evil. I seen problems with Windows NT
(mostly memory leak related) but after handling Oracle databases on
Windows 2000 or newer version, it is quite stable. However it depends on
SA of Windows server how competent they are to configure and handle
Windows server.
I am mostly supporting Oracle databases of various versions on HP,
RedHat Linux and Windows and did not find serious issues with Windows
2000+ servers. Although it is not a preferred environment but due vendor
requirements for their application (specially for pharmceutical industry
which needs validated application/databases) we need to put Oracle
databases on Windows 2000/2003 servers.
Regards
Rafiq

Anyone want to jump in on their preferred platform for RAC? Personally I
tend to lean towards Linux for stability purposes, but I'd like your
thoughts on why you prefer either platform for RAC. Specifically why
would you avoid windows (other than the fact that it's evil), or would
you?
