Thanks to everyone that submitted abstracts for our upcoming E4 conference. Unfortunately, there were more quality submissions than we had room for. Maybe next year we should expand the event to 3 days. :) But in the meantime, we have assembled what I believe is an excellent line up of (more...)

Just a quick note to remind you that the call for papers for E4 is closing in a few days (on April 30).  So if you have anything you think is interesting related to Exadata that you’d like to share we’d love to hear from you. By the way, (more...)

I got an email a few days ago . . .

Subject: Exadata / your blogs / you aren’t saying to put HINTS on everything, Are you…

. . . A peer of mine found a couple of your blogs listed below which discuss Profiles and Hints. The position he is inferring upon you is that (more...)

I was doing a little research for an upcoming presentation on Oracle 12c Adaptive Optimization and I came across a series of posts on Dynamic Sampling by Randolf Geist (one of my favorite Oracle smart guys). I could not find a complete list of the series of posts either through Google or the search function on the site where they were posted. I guessed at a couple of the url’s and got lucky. Thought it might be useful at some point in the future so I wrote them down on my blog (which is where I often keep private notes). (more...)

I got a look a new prototype for the next generation Exadata last week while doing some work with a company in Europe. Apparently there is a big push to be environmentally friendly there now and so Oracle is trying to come up with a model that uses less power and is biodegradable. The word on the street is that it won’t be available until after release 2 of the 12c database.

The new model has a few drawbacks though. For one thing, it only lasts a few weeks before you must either replace it or higher some rocket surgeon (more...)

I know no one really likes the term “tuning” these days, but it’s a short catchy word that gets the idea across. So I’ll just stick with it for the title of this post.

Note that this is one of those posts that’s not really supposed to be about how to solve a particular problem. It’s really just a story about a distraction that I ran into and I how I thought about getting around the issue and then ultimately resolving the root cause. Maybe you will find it instructive to see the process.

So I have this script that (more...)

Just a quick note to let you know I’ll be speaking at the Hotsos Symposium in March in Dallas. I’ve attended every year for the past 6 or 7 years and spoken at several of them. It has consistently been the best performance oriented Oracle conference I’ve attended. This year will be no different with the likes of Maria Colgan, Karen Morton, Tom Kyte, Tim Gorman, Cary Millsap, Frits Hoogland, Gwen Shapira, Alex Gorbachev, Kyle Haily, Carlos Sierra, Kellyn Pot’Vin, Mark Farnham, Toon Koppelaars, Andy Zitelli, Neil Gunther, Stephan Haisley, Marco Gralike, Steven Feuerstein and a host of others. Looks (more...)

Just a quick note to let you know that I updated the presentations section of my blog. Most of the talks I’ve done over the last 3 years, including Hotsos Symposium, RMOUG Training Days, Oracle Open World, UKOUG Conference and Enkitec Extreme Exadata Expo (E4) are now on the site.

Just a quick note to point out that the official white paper version of the TCO study I talked about in a previous post (Exadata vs. IBM P-Series) is now available on the Oracle web site here:

Cost Comparison – Oracle Exadata Database Machine vs. IBM Power Systems

The most interesting part of the study (in my opinion) is the quotes from the participants that are using Exadata. These quotes provide some insight into how people feel about the platform after having systems in production for a while (note that all the interviews were done prior to the (more...)

Here’s a link to a video of Mogens Norgaard discussing the upcoming OakTable World conference (click on the picture of Mogens below). Note that the name of the conference has been changed from Oracle Closed World to OakTable World.

Fellow Enkitecies Karl Arao and Tanel Poder will both be presenting at the event along with a bunch of other well known OakTable members. I may even do a 10-15 minute TED style talk at lunch time on Monday. Hope to see you there.
