KG,

yes we see the GC traffic a lot, when there are 4 production instances on each node and that is why we were interested in finding out if we could make oracle use both interconnects.

Any ideas?

Use the cluster_interconnects parameter to specify all the IPs used for GC. But there is a catch. But sometimes a NIC failure will be seen as Node failure (though it is a very very rare case).

BTW Why do you want to use both NICs for GC traffic? DO you see lots of waits for messages?
