until few minutes ago i thought that network bonding was a system to make
work two NICs as one, not 2 VIPs on one NIC, but i'm not system administrator.
In my opinion what Oracle Support says is that you cannot configure listeners to
listen to more than one VIP. It seems to me that what manual (http://download.oracle.com/docs/cd/B19306_01/rac.102/b14197/ crschp.htm#sthref733) says is that
you can configure a cluster VIP for your application using Oracle Clusterware (from 10gR2). In this case
Cluster VIP is what you initially intended for VIP that is an High Available VIP that is active on only one node. The VIPs configured and used by RAC are another thing that must be used only to configure
database clients.
Maybe that i've not well understood your need because i've not well understood if you are talking about
NIC or subnets.
