We have been secretly planning something with Kerry Osborne – and now it’s official – we will host The First Exadata Virtual Conference in the World, on 3-4 August 2011.
This conference takes place a couple of weeks after our Expert Oracle Exadata book is published (on 18. July – check out the awesome new cover design). So, we thought it’d be a good idea to run this conference, where we can explain some things in a different format, do live demos and answer questions that attendees have.
On the first day Kerry and Randy will talk about some serious fundamentals of Exadata, like how Exadata Smart Scan Offloading works and how to make the IO resource manager work for you (especially important in mixed workload consolidated environments).
And on the second day we’ll dig even deeper, with Andy Colvin talking about how to survive Exadata patching (he has patched more Exadatas than anyone else I know) and me following up with some complex performance troubleshooting stories I’ve encountered recently (trust me – there’s a LOT of issues to troubleshoot ;-)
About the Conference:
Since its release, Oracle Exadata quickly became a hit. Due to the relative “youth” of Exadata technology and internal behavior changes introduced with frequent patch-sets, there’s not much up-to-date quality technical information and know-how available to public. This virtual conference brings you a chance to learn from the leading Exadata experts, from their experience of working with real Exadata environments, from Exadata V1 to the latest X2-8. Additionally, there is plenty of Q&A time scheduled, so you can also get answers to your Exadata-related questions.
The speakers are probably some of the most experienced Exadata consultants in the world, in the field of Exadata deployment, migration, performance, and troubleshooting. Also, Kerry, Randy and Tanel are the authors of the #2970a6; text-decoration: none; padding: 0px; margin: 0px;\" href="http://blog.tanelpoder.com/wp-content/plugins/wordpress-feed-statistics/feed-statistics.php?url=aHR0cDovL3d3dy5hcHJlc3MuY29tLzk3ODE0MzAyMzM5MjM=">Expert Oracle Exadata book published by Apress in July 2011.
All of the speakers are hard-core hands-on professionals, having worked on many different real-life (production) Exadata environments of their clients. Enkitec dudes didn’t stop there, they bought a half rack for themselves, just for playing around with it. Yeah (+1 from me), some people buy a red hot Ferrari, some buy a red hot computer rack with an X on it :-)
More information, abstracts and registration:
I don’t think you’ll find an Exadata learning opportunity like this from anywhere else (and any time soon), especially considering the price!
This conference is so hot, that one of the attendees managed to sign up to it even before I had published this page to the world! :-)
I just noticed that Jonathan Lewis has announced that he’s writing a new Oracle (fundamental) internals book, due to be out in November.
So, I’m happy to add to Jonathan’s announcement, that I’m the tech reviewer of that book!
After all the hard work on the Exadata book, I didn’t want to hear about working on any book again (even if it’s just tech reviewing work), but as this is Jonathan’s book, about exactly these topics I love and focus on, I had no choice but to make an exception and become a reviewer ;-)
I’ve already reviewed a couple of chapters and this book is going to be awesome!
In May I received the IOUG Select Journal Editor’s Choice Award for my Systematic Oracle Latch Contention Troubleshooting article where I introduced my LatchProfX tool for advanced drilldown into complex latch contention problems (thanks IOUG and John Kanagaraj!).
As the relevant IOUG webpage hasn’t been updated yet, I thought to delay this announcement until the update was done – but I just found an official enough announcement (press release) by accident from Reuters site:
The article itself is here:
Thanks to IOUG crew, John Kanagaraj and everyone else who has read, used my stuff and given feedback! :-)
You should save this link in your bookmarks, for the next time you accidentally remove your database’s online redologs or overwrite some ASM disks:
Here is a link to a collection of scripts that can be used for some entertainment (well, it probably depends on your personal definition of "entertainment"...) regarding "Delayed Block Cleanout". These scripts are meant to be used in a playground environment - do not attempt to get them close to anything important as they might have some undesirable side-effects. Please read the comments in the file header description before attempting to run them.
First, a reminder – my Advanced Oracle Troubleshooting v2.0 online seminar starts next week already. Last chance to sign up, I can accept registrations until Sunday :-)
I won’t do another AOT seminar before Oct (or Nov) this year. More details and sign-up here:
I have rescheduled my Advanced SQL Tuning and Partitioning & Parallel Execution for Performance seminars too. I will do them in September/October. Unfortunately I’m too busy right now to do them before the summer.
And that’s all the travel I will do this year…
I’ll soon announce the 2nd EsSN virtual conference too ;-)
Free online stuff:
Perhaps in a month or so I will do another hacking session (I’ll plan 2 hours this time, 1 hour isn’t nearly enough for going deep). The topic will probably be about low-level details of SQL plan execution internals… stay tuned!
Steve Bamber has written up a case study of library cache latch contention troubleshooting of an Apex application with LatchProf. I’m happy that others also see the value and have had success with my new LatchProf based latch contention troubleshooting approach which takes into account both sides of the contention story (latch waiters and latch holders/blockers) as opposed to the guesswork used previously (hey if it’s shared pool latch contention – is must be about bad SQL not using bind variables …. NOT always…)
Anyway, I’m happy. If you have success stories with LatchProf, please let me know!
As a second topic of interest, Laimutis Nedzinskas has written some good notes about the effect and overhead of Flashback Database option when you are using and modifying (nocache) LOBs. We’ve exchanged some mails on this topic and yeah, my clients have sure seen some problems with this combination as well. You basically want to keep your LOBs cached when using FB database…
Ok, it’s official – the first and only Oracle Troubleshooting TV show is live now!
The first show is almost 2 hours about the ORA-4031 errors and shared pool hacking. It’s a recording of the US/EMEA timezone online hacking session I did some days ago.
There are a couple of things to note:
View the embedded video below or go to my official Oracle Troubleshooting TV show channel:
People talk about the Oracle SQL Developer 3 being out, which is cool, but I have something even cooler for you today ;-)
I finally figured out how to convert my screen-recordings to uploadable videos, so that the text wouldn’t get unreadable and blurry.
So, here’s the first video, about a tool called MOATS, which we have built together with fellow OakTable Network member and a PL/SQL wizard Adrian Billington (of oracle-developer.net).
Here’s the video, it’s under 3 minutes long. Play the video in full screen for best results (and if it’s too slow loading, change it to lower resolution from HD mode):
Check it out and if you like MOATS, you can download it from Adrian’s website site (current version 1.05) and make sure you read the README.txt file in the zip!
Also thanks to Randolf Geist for finding and fixing some bugs in our alpha code… Note that MOATS is still kind of beta right now…
P.S. I will post my ORA-4031 and shared pool hacking video real soon now, too! :-)
P.P.S. Have you already figured out how it works?! ;-)
