RAC Perf Tuning Seminar in Istanbul, Turkey

For those who attended my 2-day training event in Istanbul, I wish to express my sincere thanks for the participation. For me, or any speaker, the privilege of having your attention for 2 days away from your work and family, means a lot. Some folks came all the way from Ankara and had to go back to work the following day. I hope you all got to learn something worthwhile your time.

The scripts are located in: http://www.proligence.com/racperf_istanbul/scripts.zip The password and userid is the ones I gave you in the class.

I also want to reiterate my earlier request to send me your detailed and honest feedback at arup@proligence.com. You may want to write it in Turkish, if that is more convenient. The important thing is to provide the feedback; I can always translate using Google.

Thanks, Hande and Madalina from Oracle University for arranging it. Much appreciated. Now I am off to Estonia.

OOW09 Session#4 DBA 11g New Features

For all those who came to my last of my four sessions - 11g New Features for DBAs - I appreciate your taking the time. It was a pleasant surprise to see about 500 people showing up at a lunch time slot on the last day of the conference.

Here is the presentation link. I hope you enjoyed the session and found it useful.

OOW09 Session# 3

I just finished the third of my four presentations - SQL Plan Management. Considering it was at 9 AM on the last day of the conference, right after the big Aerosmith concert, I was expecting a lot less crowd. But, to my pleasant surprise about 150 brave souls turned up. Thank you all. I hope you found it useful.

Here is the presentation material. While you are there, feel free to browse around. And, of course, I will highly appreciate if you could send me your comments, either here or via email - whatever you are comfortable with.

OOW09 My Session#2

Today I delivered the second of my four sessions - "Upgrade Case Study: Database Replay, Snapshot Standby and Plan Baselines".

For those you attended, I thank you very much. Here is the presentation.

OOW Day2

Why do you come to Open World? I'm sure we will get all kinds of reasons, as many as there are stars in the sky. Some predominant themes are - getting to know more about the Oracle (or related) technologies by attending sessions, reconnecting with old friends and building networking. Of course, getting freebies from the Exhibit Halls, I'm sure, can't be far behind as a motivator.

I come to OOW for all those reasons as well. But high up in my list is the visit to the Exhibit Halls. No; not for the tee-shirts that do not fit me and graphics I don't really dig. I visit the demogrounds and exhibit halls to know about the products and tools that I should be aware of. Where else would you find 1000+ companies advertising the products at one place? Sure, I can call them and find out; but ho do I find them? OOW exhibit halls are prime "hunting" grounds to look for new ideas and tools that I should be interested in; or at least be aware of. I can not only look at the tools; I can actually get some relevant technical facts in 5 minutes which might take weeks of scheduling and hours of marketing talk. And, if I decide the product is not relevant; I can always walk away. I have the privilege of walking away; they don't. If I call them to my office, "they" have that option; not me :) If I find something attractive, I can always follow up and get to know more.

Oracle demogrounds are even better. Not only I can meet Oracle PMs there; but the people who never come out to the public world - developers, development managers, architects and so on. These unsung heroes are mostly the reason why Oracle is what it is now. I meet the known faces, get to know new ones and establish new relationships. They hear from me what customers want and I learn the innards of some features I am curious about.

So, I spent almost the whole day yesterday navigating through demo grounds and exhibit halls. I could cover only a small fraction. In between I had to attend some meetings at work. Going to OOW is never "going away". I wish it was.

OOW09 - RAC Performance Tuning

For all those who came to my session - many, many thanks. There is no better sight for a presenter than to see a roomful of attendees, especially with people standing near the walls. The fire marshal was not amused probably; but I was grateful. The harrowing incident of a blue screen of death on my PC - not just once but twice - just before the presentation was about to start was enough to throw me into a panic mode; but the third time was a charm. It worked. Phew!

You can download the presentation here. And while you are there, look around and download some more of my sessions as well.

Thanks a lot once again. I'm off the keynote now.

Open World 09 Starts

Oracle Open World 2009 has officially started with the User Group sessions today. I am presenting a session today. I started off by registering and getting my cool Blogger badge holder, hanging off the even cooler ACE Director lanyard.

I went off to the first session of today on the IOUG bucket - Workload Management by Alex Gorbachev. Alex is one of those people who know their stuff; so there is always something to be learned from there. Alex successfully demonstrated the difference between Connection Load Balancing and Server Side Listener Load Balancing, with pmon trace to show how the sessions are balanced. It sheds light on the question - why Oracle is not balancing the workload.

If you didn't attend this, you should definitely download the presentation and check it out later.

Most Striking Object at Open World 08

What was the most amazing thing I witnessed for the first time at OOW 08?

Hands down, it is the compostible drinking cup! Yes, compostible, not recyclable. It looks just like any other plastic (not paper) drink cup you see at almost any public water dispensers. The difference? It's made of corn syrup, I was told, not plastic and hence compostible. Wow!

I am not a green fanatic; but I consider myself a responsible adult concerned about the environment doing his share to reduce the landfills, pollutions and paper consumption. I do things that are practical: I don't print something I can read on the monitor; project emails, powerpoints on the screen/projector while conferring with colleagues rather than printing; use back sides of printouts to scribble; use 2-sided printing; donate kids' toys and cloths to charity rather than throw them in trash and so on. But there are some things I just couldn't jettison; at least not yet. One of them was the ubiquitous plastic drinking cup and the bottled water. The convenience of the water bottle was just too much to ignore and my lazy bones reigned over my conscience and I always gravitated, albeit a little guiltly, to the water bottle.

OOW'08 Oracle 11g New Features for DBAs

It was my second session at Open World this year. It was full with 332 attendees with a whopping 277 attendees on wait list! the room capacity was 397. Of course, the room did have some fragmentation and not everyone could make it.

Here is the abstract:

There is a world outside the glittering marketing glitz surrounding Oracle 11g. In this session, a DBA and author of the popular 11g New Features series on OTN covers features that stand out in the real world and make your job easier, your actions more efficient and resilient, and so on. Learn the new features with working examples: how to use Database Replay and SQL Performance Analyzer to accurately predict the effect of changes and Recovery Manager (RMAN) Data Recovery Advisor to catch errors and corruption so new stats won't cause issues.

Thank you very much for those who decided to attend. I hope you found it useful. Here is the presentation. You can download it from the Open World site too. Please note, the companion site to see al working examples and a more detailed coverage is still my Oracle 11g New Features Series on Oracle Technology Network.
