Dan, Jeremy,
I think it depends on your definitions of "having RAC".
For me running CRS and ASM in *clustered* mode does mean RAC.
"Having RAC" also might assume having to buy RAC license. Don't take
my licensing knowledge for 100% but...
Recently, Oracle allowed using CRS for free to its customers with
Linux support. Otherwise, you have to buy at least one RAC license.
However, clustered ASM instances - do they require RAC license or not?
I would think they do but its pure speculation.
Regards,
Alex

Matt,
Are you sure? I see no technical reason why this would be a problem
with the following stipulations:
1. You can't have different OSes.
2. You must use Oracle Clusterware, have shared storage, and have
clustered ASM.
Given those two requirements, I think you could do this with
multiple single-instance databases on different nodes. Those nodes
would be clustered for purposes of sharing ASM disk groups.
All that said, I haven't tried it, but I have thought about the
feasibility several times and those that I've talked to about it
didn't think it would be a technical issue. Now, why you'd do this
when an OCFS2 filesystem achieves the same purpose with somewhat
less complexity (IMO) is another discussion.

Subject: Q: asm on serveral nodes (no RAC)
Hi all, I’m wandering is possible to have different computers using
the same disk groups in ASM without RAC? Even on different O/S ?
The main idea is to define a share area for all the development
databases.
