Having an Oracle_home on each node is ill-advised in my opinion. It is
too easy, and I have seen it happen far too many times, that something
happens to the passive node's ORACLE_HOME that is only discovered when a
failover event occurs. Having one ORACLE_HOME that is on the SAN and
shared between nodes is ideal - if you really want to have a spare
ORACLE_HOME so you can easily recover from bad patch applications, etc.,
then make it a habit to clone your existing home as a backup before
applying the patch, then removing that once you know the existing home
is good.
Other than that, I am a general proponent of the architecture described
below, and we have many many customers who use this design for their
veritas environments.
Thanks,
Matt

If you are just starting out with Oracle and VCS there are many
different ways of doing things. We have every database in it's own
resource group along with the listener and the mount point for the data
files. ORACLE_HOME's are installed separately on each node in the
cluster in the asme location. TNS_ADMIN also points to a local location
on each node outside the ORACLE_HOME. This is only one option of how to
do things. Some locations put all databases into one resource group and
fail them all together. Some locations put the oracle software under VCS
control as well so that swings with the resource group. It all depends
on your specific needs.
Make sure users, groups and kernel parameters are in sync and that
filesystem/directory permissions are set correctly so the failover
doesn't fail.
Good luck.

We are on Sun servers and multiple oracle versions with veritas
clustering software. Is the a document or website out there explaining
veritas as it pertains to oracle? I have looked on metalink and
everything deals with RAC. We are not running RAC.
