Slightly off topic, but related question... In 11g Oracle started recommended that we have a separate Grid and Oracle Home. In 11g, I didn't see a good reason to do this. Seemed like extra cluster. Oracle often makes changes like this as part of a phased in change in later releases. I am wondering if people see more use for the grid home in 12c? Might work better with the pluggable DB option. I admitted have not spent a lot of time looking at 12c. I don't expect to use it at all for atleast 1-2 years minimum.
