Pete - Thanks for that explanation. I was one of those assuming Grid <=> RAC. Dennis Williams DBA Lifetouch, Inc.

Yep. You're missing the simple fact that grid is bigger than RAC. Sure, R= AC enables a lot of the grid technology but you can also have non-clustered= databases in a grid environment on different OS's.

Extend that question into the realm of 'grid' computing. RAC requires a het= erogeneous environment within the cluster. This means = that a RAC cluster is not really grid friendly. It is only able to 'shift' = processing requirements within itself and cannot take = advantage of that underutilized server sitting next to it in the data cente= r.
