Has no one seen how much $ORACLE_HOME/rdbms/mesg/oraXX.msb file gets = hit? Granted, it's not extreme and I'm sure it's picked up in the FS = cache, but it's still activity that I'd just as soon not have hitting = the SAN.

My $.02,
Rich

I have read this thread, and haven't seen any one mention hardware clustering and your file systems..
We typically run every database in a HW clustering config (SUN cluster, Veritas VCS,etc). We found that placing the binaries on the SAN allowed = us
to "fail over" a little more effectively. Just one way of doing it.... = Works
better with our overall strategy. When the hardware goes "south", the resource groups have the Oracle binaries defined as a component, the = file
systems for the binaries/data files fail over to the member node of the cluster.

Another "standard" has been to use the internal drives for OS required = items
(TMP, SWAP, /opt, /home , etc). All products/applications get to live on = the
SAN. Now there are exceptions as vendors like to force the use of = specific
file systems(why?) like /etc or /var/opt.
