Body: 
Cache Fusion the fundamental to performance in RAC by reducing the need to go to disk for the data and getting it from the memory of another instance directly. But it is also a source of a lot of mystery, myths and misconceptions. This session will explain in clear terms what cache fusion can or can’t do by traversing the course of a buffer from the disk to the instance and then to the others. Also covered will be the different states of the buffer, the global locking mechanism, the need for a CPU and I/O as opposed to a super-fast interconnect, the cause of the different global cache related wait events and how they can be resolved. All will be shown with live demos.
