if you are strapped with 10.1.0.5 for compatibility purposes, I would definitely try and get the other pieces of the RAC stack on later versions, if possible. Get your cluster running the latest clusterware you can, same goes for ASM,OCFS/OCFS2 if you are going to use those. We use RHEL 4 with a 2.6 kernel. I haven't tried running 10gR1 on it. Check the certification matrices on metalink. On 3/20/08, Allan Nelson <anelson77388@xxxxxxxxx> wrote: > > I've been tasked with building a 10gR1 RAC around 10.1.0.5.
