I have so far avoided writing such pointer blog posts which only refer you to another article, but I have to do it with this one. Adrian Billington has written an excellent article on performance of Oracle 11g PL/SQL function result cache. His article is a good example of a thorough, well organized and well written technical content. I really enjoyed reading it and thanks to his thoroughness, he has just saved me some precious time doing that research on my own.

NB! Dates updated: After a 1.5 year break, this year’s only Advanced Oracle Troubleshooting training class (updated with Oracle 12c content) takes place on 14-18 December 2015 and 11-15 January 2016 (I had to reschedule the start from November to December). So sign up now if you want to learn new cool stuff!
