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.

OOW14 Session: Cache Fusion Demystified

Thank you all those who attended my session Cache Fusion Demystified.

As I mentioned, it was impossible to fit in a demo within that compressed 45 minute timeline. I put the details of the demo in a separate file with all the scripts and instructions that allows you to execute the demos at your own site.Download the slide deck as well as the scripts. In addition I have also written a whitepaper to explain the concepts clearer.

Download the slides, the paper, the demo scripts and instructions here.

I sincerely hope it demystified one of the most complex topics in Oracle RAC. As always, I would love to hear from you about your experience.
