with the VMWare solution did you have 2 virtual machines simulating 2 nodes
and have a 3rd virtual that stored the datafiles etc? assuming
that is the case, what mechanism did you use to have both nodes be able
to access the same datafiles - i.e. did you store the Oracle components
(datafiles, etc.)
on raw devices on the 3rd virtual and then have the 2 nodes have the
same share (say windows) or remote nfs mount (say linux/unix) to the
location? we are confused how to accomplish the 'sharing' of
data devices without file/OS locking or permission problems.
