Hi
Windows 2003 x64 have no memory limits (8TB per process) and it´s a very
stable platform althought not as stable as Unix because of virus and
continuos updates that forces to reboot.
Please take a look at page 13 of the following ppt:

es-rac-64-bit-windows-Best-Practices-Oracle-Database-10g-RAC-Microsoft-64bit
-Windows-Commitment-Partnership-Regi-on-ppt-powerpoint/
Standard x64 edition now support 32GB RAM and cost 1/5 of EE.
Greetings.
Juan.

Asunto: RE: Oracle RAC on Win vs. Oracle on Linux
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?
