We have two independent Sparc/Solaris systems sharing Sun's disk
arrays. Both systems are on the same sub-net and have a separate high
speed Ethernet connection between them. Is it possible to configure an
active-active, HA, redundant, Oracle RAC on these systems without using
Suncluster or other non-builtin clustering software? If no, what would
be the minimum additional software/configuration required? If Oracle
built-in software can be used, what component will be required at the
very least?

I am trying to keep the number of components minimal, yet build a
highly available, possibly fault tolerant, configuration. Would prefer
to use raw partitions rather than LVM and such which increase
complexity.

I know there will be insightful responses. I thank you in advance for
your help.

Oracle Data Guard maybe ?

Note : you need Enterprise Edition for it.

No version number?

If 9i no it is not. You don't have a sharable file system unless you go
to raw devices. If 10g ten yes.

RAC, however, has to do with shared storage and your statements about
sub-net, etc. indicate a lack of understanding of RAC and how it works.
I'd suggest a quick trip to http://tahiti.oracle.com for some reading
on concepts.

Oracle CRS ( cluster ready services ) software with 10g can provide the
node with clustering services to run ran. Indeed with 10g you cannot
avoid CRS if you want to run RAC.

With 9i you would need sun clusterware.

Sure you can run raw with 10g or with 9i RAC if you wish to.

If you have 2 sun sparc systems with shared disk, you are all set to
start learning. It is best of course if you have systems that are
dedicated and yours to operate as a development and research
environment with impacting applications and business systems.

If these systems have other responsibilities well then you need to
proceed much more carefully.

I am gradually navigating through Oracle documentation. My knowledge of
RAC is poor, though I have used clusters and Oracle before.

I mentioned sub-nets in case someone has ideas about virtual IPs,
network hearbeats and such. Isn't a high speed interconnect required
for data cache syncing?

Shouldn't that be Veritas?

For the mem-interconnect Gig either is fine except in the most
extreme situations where you might wish to look at InfiniBand.

VIP's are required for 10g RAC: Not 9i.

Read the docs at www.sun.com

Any more questions?
