I'm running Oracle on one server. And I'm considering moving to RAC of 2 server.
Current CPU is 3.60GHz and 8 cores.
To achieve the same performance on RAC, Is it sufficient to prepare 2 CPU of 3.60GHz and 4 cores? Or 2CPU of 3.60GHz and 8 cores?
And about CPU usage, if current server has access from multiple clients when it is one server and oracle process is always at around 40%. If I used RAC, the load will be distributed and will it be 20-25%?
