Re: Oracle RAC VIP networking question

Unfortunatley - I'm a networking person trying to assist our UNIX/DBA team. But, yes, I agree with your understanding of Network Bonding. It bonds 2 or more NIC's together to aggregate bandwidth which should have nothing to do with VIP's on multiple subnets.

The bottom line is, we have a 3 node cluster. Each node has a public, private and (what we call) an isolated batch subnet NIC (3 NIC's total per node). Our Application vendor indicates that it is "strongly" encouraged to have this isolated network (where bulk batch processing takes place) and not compete with the public NIC where the clients access the application. In total, this is 3 seperate IP subnets per node. Our Unix/DBA's need to have multiple VIP's to service the applications that need to use the public and isolated batch subnet. One VIP to listen on the the client side for the actual application. And another VIP that will listen on a totally different subnet (the isolated batch network) that of course has it's own NIC. So, our concern is from what we have heard so far is that it appears the VIP per node that any application can use is only available on the "public" facing NIC
