There is a "cluster verification" script-and-binaries which you use to make certain that your server has all it needs to run Oracle RAC (11.2.0 specifically). That tool tells me that I must run ntpd (good...) and I must run it with "-x" (ehh?). I'm failing to dream-up a good reason why Oracle RAC might want reduced time-keeping accuracy. Are they really looking for fewer "unnecessary" local clock corrections? Or a wider tolerable time-spread among the cluster members? Fewer "stolen" cycles in kernel mode?
