Oracle
9i RAC on Solaris is problematic. Here's why:
There
are two choices for the underlying cluster server: Sun Cluster 3.0 and Veritas
AC for RAC. If you decide to use Sun Cluster, you still need to buy
Veritas Volume Manager with the cluster option, since Sun doesn't really have a
cluster-aware volume manager. Then, Sun's clustered file system isn't
supported by RAC, so you have to use raw devices.
If you
use Veritas AC, its hideously expensive. It's tiered pricing, but for tier
1b (the low end - like a sun 420r) it lists at 21k per node. If you do
decide to go with Veritas, you're required to either have an EMC or HDS
storage array - the Xioech isn't supported. Beyond these requirements,
you need a minimum of three quorum disks that cannot be shared with any
other data and two dedicated heartbeat links. Once all this has been
implemented, you're limited to only two nodes in a cluster. It's never
seemed worth it to me.
A much
more sensible platform for deploying RAC is linux - no need to buy separate
cluster software, the clustered filesystem is built-in, you can go multi-node,
etc. With linux, you can run the database off of a Netapp if you want,
which is another option not available for RAC on Solaris. It just seems
like Oracle is trying to push RAC on linux at the expense of RAC on any other
platform.
(FULL
DISCLOSURE: My company has built a 9i RAC appliance based on Linux, so I won't
even pretend like I'm not biased. Even with my unbiased hat on, though,
RAC on solaris seems less than ideal)
Thanks,
Matt

Subject: Anyone installed Oracle 9.2 RAC on solaris 9We have been given the funding to install a production Oracle RAC environment. I am wondering if Solaris 9 has any bugs we should know about.Looks like we will be installing the following:Oracle 9.2 (64-bit)RACSolaris 9 (64-bit)Veritas DBE/AC version 3.5 - Veritas has a advanced cluster for Oracle9i Real Application software.Our storag media is on a SAN solution using XIOtech and we will need to order an HBA.Any information on bad ideas/gotchas would be most welcomed.Many Thanks,-Lizz
