Oracle RAC VIP IP (static or movable) ...

Hi All:

I'll keep this question simple. Let's pretend that you have a pair
of
servers that will run Oracle RAC.

For simipicity sake, forget about the
private interconnects between
the two servers (I've got those covered over two
different NIC
interfaces and, in fact, over different physical NIC cards).
Also for simplicity sake, lets pretend that we don't need IPMP (we
of course
do, and I have that covered too, but lets keep it out of
this example):

Ok,
here is what we have left with our single "nxge" NIC inetrface:
===============================================
server1:
===============================================
  nxge0: 192.168.10.20
(public IP address)
  nxge0:1: 192.168.10.21 (virtual IP
 address)
===============================================
===============================================
server2:
===============================================
  nxge0: 192.168.20.20
(public IP address)
  nxge0:1: 192.168.20.21 (virtual IP address)
===============================================

The public IP addresses stay
with the physical interface (they do not
move), and are used for admin access
(ssh login; patching; etc.).

The virtual IP addresses may or may not move
between machines. I
don't know for sure because our DBA is somewhat new to
RAC, and
can't answer that question for me.

So... In RAC can, what Oracle
refers to as the VIP IP address,
be moved between servers by Oracle RAC
monitoring processes
(not unlike how VCS does it)? Of does it always remain
tied
to one server?

Thanks in advance,
Noel
