Hi Olivier,

I do plan to upload the slides. I even consider re-doing the presentation with audio, similar to that one.

Stay tuned.

Hi Christo,
really enjoyed your presentation at ukoug 2011, seems like the very short time you had to present your stuff was a little bit frustrating ;) Any chance you upload the slides you’ve used which looked like a little bit up to date as compared to the existing presentation from 2006 ?
Thanks and Best Regards,
Olivier.

Hi Odi,

I checked out your blog. Don’t use transparent hugepages for Oracle’s SGA. Use the fixed one for the sga.

To answer, your question on SGA – you need to first estimate how much memory you will need for connections, sorting, and pl/sql arrays. i.e. it depends on your application.

But the bigger question is … 6GB server running Oracle? In 2011? With the low prices of RAM, and the fact that you do not pay licensing fee for RAM, it only makes sense to use the maximum available on the server.

I want to run Oracle without swap. Given the RAM size, how large can SGA/shm be to run it safely? See http://www.odi.ch/weblog/posting.php?posting=643
