Week ago I was back home from the 10th Hotsos Symposium, the best performance dedicated Oracle conference in the world.
This was rare opportunity to see extraordinary presentations and discuss advanced Oracle topics. Inspired by Jonathan Lewis new book Oracle Core: Essential Internals for DBAs and Developers book I was happy to attend his Training Day.
I was lucky to speak at this jubilee Symposium about mutex internals and mutex contention.
Many thanks to the Hotsos team for this great conference.
