Pete - Thanks for that explanation. I was one of those assuming Grid <=>
RAC.

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. Add Streams and the ab= ility to have cross platform transportable tablespaces and you'll see more =of the overall grid environment.

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. I asked this question of an Oracle employee recently =
and the response was that RAC does indeed fit into Oracle's grid strategy, = but there are not any plans to enable a homogenous RAC =
system. Am I missing something?

ted, your availability is only good until your next patch (Oracle, OS, or 3=

me time. In the case of Oracle patches, it's mandatory at least thru 9.2.
