Speaking at E4 2013! … and some Exadata Patents good stuff Reply

I’ll be co-speaking with Tyler Muth at E4  and we will be talking about Performance Visualization… some of you may already know that I’m really a big fan of Tableau and just to give you an example on what the tool can do I’ve consolidated all the different viz that I’ve done during my sizing & performance gigs here http://goo.gl/xZHHY and Tyler has also been doing a lot of Exadata performance & benchmarking gigs lately and there were a couple of times where we collaborated on specific viz (him doing it on R) just to validate each other’s work. In short, we are passionate about this stuff. And we are going to be awesome :)

The session title is: Performance data visualization with Oracle R and Tableau

SQLTXPLAIN quick tips and tricks and DB Optimizer VST 1

I have a longer draft post about SQLTXPLAIN.. but I haven’t finished it yet so I’ll just go with the quick post for now.


I’ve been using SQLTXPLAIN for quite a while, and I can say I’m a really big fan. It’s a cool tool to use for systematic SQL Tuning so I got them all neatly documented here http://karlarao.tiddlyspot.com/#SQLTXPLAIN.
