Home -> Community -> Mailing Lists -> Oracle-L -> RE: RAC nodes
Then your rep needs more knowledge. RAC works with geoclusters as well. D= epending on the clustering technology, clusters can now have nodes 10's of = kilometres apart. I know some of my colleagues got it to work on two lapto= ps separated by 300 km or so in England using the internal Oracle network. =Obviously not a production configuration though! :)

Subject: RE: RAC nodes
Carol,
One of the biggest challenges you are going to have is, as someone else mentioned, sharing disk over the large geographical location. Last I spoke=
with an Oracle rep, this had only been done over a short distance - like a couple of hundred yards. Seems unbelievable to me that this *can't* be done, but it's what I've been told.
So someone in your organization needs to solve that problem first. If it does not exist, then you are stuck with either replication, or one database=
server shared by all.

Raj,
I recently spoke with someone that is considering putting in RAC in this =
configuration.
We don't know of anyone that *has* done this, and on the flip side, we =
couldn't think of any other
reasons this solution might be problematic except for the network.
I'd like to hear about similar RAC experiences (servers split over =
geographic locations)
from others on the list if they have tried it. =
