Re: Oracle RAC on Win vs. Oracle on Linux

Richard,

What about the 64-bit options.... 64-bit would seem to address your concerns 
with memory, etc... ? I've also heard that the multi-threading becomes much 
less of a problem with the 64-bit OS.

Of course the down side is the simple fact that WIN releases are always way 
behind everything else. Witness the current situation with 11gR2.

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?
