TweetShareSharePin0 SharesThe afternoon had one of the sessions I knew I would enjoy the most before I even got here. It was Carly Millsaps “Thinking clearly about performance”. The reason I anticipated a great presentation is not just Carlys knowledge in the area, but also the fact that he is fast becoming the best presenter in the Oracle area. This presentation was no different, he covered a lot of topics and still made it seem like there ws no rush […]

TweetShareSharePin0 SharesThe afternoon was kicked off with a presentation on using APEX in large projects by Dimitri Gielis. These re my notes for what Dimitri told us.

The first session was the start of the APEX symposium. It was supposed to feature Scott Spendolini and an overview of APEX 4.0. He had been delayed so the […]
Two good posts that are related
TweetShareSharePin0 SharesI like when a blog I follow links to a blogpost I have already seen and that I thought was a gem. I used to happen quite frequently when Cathy Sierras blog was active, but it still happens.

This week it was […]

I wrote an article about it a while back where I show how the ITL works and how it impacts performance in certain situations. The basis of the article is a page locking scenario I encountered. Sure, page locking is not possible in Oracle, but an ITL wait is very similar to a page lock. You find the […]
