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.
