Hi
We have a 2 node RAC for one of our new applications. There are 2 sets
of application/web servers; each set located on different building separated
by about 3 city blocks. But, both the RAC nodes are in one of the buildings.
The management seemed to be inclined to want to separate them in different
buildings. To me that does not sound like a great idea, with interconnect
traffic and such. Questions:
1) Are there any sites that use RAC 'geo-cluster' mode?
2) Would running the RAC in 'active-passive' mode help in case of geo
cluster type solution? What kind of interconnect is used by sites that have
geo cluster type RACs?
PS. I am aware that RAC is not a DR solution, going for a dataguard would be
a good DR solution.
Ram.
