Personally, I like having local ORACLE_HOMEs for "small" clusters (less than 15 nodes or so). As was mentioned, you can have multiple cluster filesystem ORACLE_HOMEs, but that's sometimes challenging to manage and I don't think it provides any great benefit over local ORACLE_HOMEs unless you have very large clusters (greater than 15 or 20 nodes).
You may also want to consult an excellent recent whitepaper written on this topic by an excellent technician at Oracle. http://www.oracle.com/technology/products/database/clustering/pdf/oh_rac.pdf

Can you guys give me opionions reasons why to have the $ORACLE_HOME product on the cluster filesystem? I believe on benefit for not doing this is when you upgrade you can bring one node down at a time and upgrade. Also - does having ASM and using RAW matter with this question? Thoughts/opionion?
