NOUG Session: How Cache Fusion Works

For all those attended my session at Northeast Oracle User Group at Babson College in Wellesley, MA. Have you ever wondered how Cache Fusion knows where to get the block from? Or, how block locks vary from row locks? Or you are confused about the meaning and purpose of various Global Cache Service (GCS), Global Resource Directory (GRD) and Global Enqueue Service (GES). The session was meant to explain how all these actually work under the covers with live demos.


I hope you found the session useful and entertaining. As with all my sessions, I use slides as an aid to presentation; not to communicate the concepts. I have written an accompanying paper which explains these in detail. You can download the paper here. Or, the presentation here. All the scripts I used can be downloaded here.




As always, your feedback will be greatly appreciated.
