Re: asm on serveral nodes (no RAC)

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.

No, it is not possible to do this without RAC.

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.
