Subject: why are some applications oracle but not RAC compatible?

Can anyone tell me why an application would be compatible with oracle but not 
rac? I'm assuming it must have to do with connectivity, but not sure why that 
isn't transparent to all applications?
Thanks in advance.>>

You'd have to document where an application can make such a statement.  It's 
probably not exactly true.  What often happens with some prepackaged software 
for smaller implementations is they've never been tested or validated to work 
with RAC, or perhaps the vendor or the company supplying support has no 
experience with RAC, and therefore may prefer not to support such an 
installation.  These would be valid reasons to run away from whatever they are 
selling.

I do know of some older database monitoring software supplied by major vendors 
that do not consider a RAC environment in their code base when reporting 
errors, but even they do not emphatically state their products won't support or 
run on RAC.  They do, it's just that some features may not work properly.

 Chris, can you document how you arrived at this determination?  Or was this 
simply something that was expressed verbally?
