Oracle RAC Patch Application

Hi Gurus.

 

I haven't done much of the work on Oracle RAC, but I was having a
serious debate about Oracle RAC verses SqlServer 2005 clustering option
(trying to defend Oracle) with my Project Manager, when he raised the
point that if you have 50 instances in Oracle RAC, and you have to apply
a patch, you'll have to apply patch on every single instance. Whereas in
Sqlserver 2005, you would apply the patch on one instance and it will be
done on all of them, just like that. 

 

I was not sure about his argument cuz I've never applied a patch on
Oracle RAC, but those of you who have experienced this, may have a
better comment on this. Will you please share this here so that I get my
concepts clear about Oracle RAC before getting engaged into any such
debate again?

 

Thanks.
