Dick,
Thanks for your response. I am supporting Oracle databases on Windows since
2003 (on other platforms since 1988) and never got a single 'blue screen of
deaths' for Windows 2000 / 2003 servers yet. I think credit goes to some
excellent US Based Server Admin support. When I joined that client I moved
number of Windows databases to Linux but where application was supporting
databases on Windows only we had no option.
As informed earlier Linux is the preferred platform for this client but if
requirement for Window based databases which host application as well as
database on Windows server we have no option but to put database on Windows.
These databases are mostly smaller in memory requirement so we don't hit 3GB
limits.
Point still remain the same, they run quite normal without any serious memory
or other resources issues on Windows 2000/2003 servers. Due support issues, now
Windows 2000 servers either has to be migrated either to 2003 or 2008 servers.
Regards
Rafiq

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.

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?
