I agree with Mark that OH can be a single point of failure.

I think it comes down to how much risk the project can tolerate. During development, I've seen configuration and hardware issues cause individual mountpoints go missing. I've had a senior DBA try to be cute and rm * at the wrong place. In production, an SA blew away the oratab file. Any of these would cause problems for the whole cluster if it has a shared OH.

These type of problems _should_ be rare. Is the protection worth the administrative cost?
