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

and here’s the abstract:


IOsaturationtoolkit-v2 with Exadata IORM and AWESOME text graph 2

I’ve got a new version of IOsaturation toolkit which you can download here http://karlarao.wordpress.com/scripts-resources/ and it has a cool script called “smartscanloop” that shows you the Smart Scan MB/s per database across the Exadata  compute nodes.. it’s a per 2secs sample so that’s a pretty fine grained perf data and near real time text graph. Very useful for doing IORM demos and monitoring what database is currently hogging the IO resources and since it’s presented in a consolidated view you don’t have to go to each Enterprise Manager performance page and have a bunch of browser windows open.

The SECTION 1 is what I usually use to validate the IO numbers on the database side from my Orion (see oriontoolkit here) and Calibrate IO runs. I’ve been using it for quite a while on new RAC/non-RAC installations from client sites.. and I used it heavily on my R&D server while continuously enhancing the toolkit


Fast Analytics of AWR Top Events 2

I’ve been working on a lot of good schtuff lately on the area of capacity planning. And I’ve greatly improved my time to generate workload characterization visualization and analysis using my AWR scripts which I enhanced to fit on the analytics tool that I’ve been using.. and that is Tableau.

So I’ve got a couple of performance and capacity planning use case scenarios which I will blog in parts in the next few days or weeks. But before that I need to familiarize you on how I mine this valuable AWR performance data.

Let’s get started with the AWR top events, the same top events that you see in your AWR reports but presented in a time series manner across SNAP_IDs…
