CBO Statistics on 11g: How to reduce poorly performing Execution Plans

with 11 comments

Today, October 23 at 4:00 pm GMT (London time), Mauro Pagano will be presenting an interesting topic in CBO Statistics from Support perspective: what works and what almost works. This presentation is not that much about explaining features, but more about sharing Mauro’s experience regarding CBO Statistics. As many of you know, Mauro is one of the top Oracle resources when it comes to SQL Tuning hands-on within the Query Tuning team at Oracle Support.

This Webinar has registered over 600 participants, and I would not be surprise many more will join today. If you are interested please try to pre-register since the Webinar closes when it reaches 1000 participants.

Webinar will start at 4:00 pm GMT (London), 8:00 am San Francisco time, 11:00 am eastern time (Orlando!).

I (Carlos Sierra) will be there answering posted questions. Abel Macias and Steve Dixon will also join to help Mauro answering questions, which we expect to come in large numbers during the Webinar. This is a hot topic, since poor CBO Statistics causes more SQL to perform poorly than any other factor.

I hope you can attend live. If you cannot make it, you can always review the recording after a few days.
