It was started by Tim Hall in 2016. This is a Thank you community post. There are so many experts posting on Oracle related forums, doing blog posts, sharing their scripts with everyone. All of you are doing a great job. I would like to mention three names especially:

Tim Hall : Tim is a legend ! I don’t consider something a new feature until Tim writes about it 😀

Jonathan Lewis : I don’t think there is anyone on this planet who has even once worked on a performance problem and hasn’t gained something from the knowledge shared by him on forums or in one of the blog posts.

Tanel Poder : His hacking sessions, blog posts and scripts are awesome. And ashtop is amazing man !

Thank you all of you. We learn from everyone of you. Keep rocking !
