RE: 10g RAC -- Multiple DB's and mixed OS

I'm not disagreeing with you that Oracle software on Windows fits about as
nicely as a 3-legged pink elephant in the front row at a funeral.  

The point I'm making is that a 100% windows shop likely has a better chance of success with Oracle on Win than Oracle on Lin.  

Your example of "a number of sites" that gave up on RAC on Windows may in fact be a testament to the poor fit of RAC on windows and not Windows. Indeed, Windows is really wierd with raw partitions..and OCFS on windows is OCFS--on windows. A CFS that is fully supported by Microsoft
that supports direct/async IO, dynamic online growth, mountpoint (no
"letter" drive limit),

shared Oracle Home (a choice) and other such features might make the
"fit" for

RAC on windows a LOT better, wouldn't you think?  

The rats-nest of the registry and the fact that it is all but impossible to uninstall RAC from
Windows is an entirely different story.

	The outfit that I work for has done both many times. RAC on
Winders is always a nightmare both during setup and then operationally. I'm familiar with a number of sites that have tried and given up on RAC/Windows. It's just too unmanageable, too unstable, too costly in terms of time. Any flavor *ix is better. Personally I don't really like RAC on Linux, but that wasn't part of the question.

                so a complete MS shop with no linux experience will be able to run RAC on linux far easier than on windows. Uh huh.                  

                and all the people that run it on windows successfully are just kidding themselves?

                        If Linux is available as a choice, make both nodes Linux, you will be much happier, even if it's a completely MS shop!
