is oracle 10g really oriented for grid computing?

Hello all, I known this is a SQL Server forum, but some people maybe have worked with oracle and can help me.

Microsoft's article "http://www.microsoft.com/sql/prodinfo/compare/oracle/mythandreality.mspx :"

reads as follows:

"Oracle's purported Grid enablement in 10g is based on its Oracle Real Application Clusters (RAC) technology that is no more than a local cluster. RAC is a local cluster of computers with no geographic distribution capabilities. This marketing campaign relabeled existing features to exploit current industry trends. "

My question is how can I support the above paragraph? I would like to known more reasons about why oracle grid is a local cluster instead of grid computring oriented.

Thanks in advance.

Hernán.

Hernan,

RAC is just like SQL Clustering. I don't think it like electtricity natrional grid

RAC is also a new name for Oracle Parallel Server which has been around for a bit.
