Hotsos Symposium Training Day 2009 with Jonathan Lewis

We had a higher percentage of attendees stay for Jonathan Lewis' Training Day this year. Jonathan's topic was "Understanding Troubleshooting".







As always, Jonathan got rave reviews, and we're really pleased to have hosted him again this year.

Hotsos Symposium 2009 - Final Day

For 8:30 on the Wednesday morning after the big party night, Chen Shapira drew a nice crowd (see below) who wanted to learn about the "Seven Sins of Concurrency":





"Oracle Performance for Developers (and the DBAs Who Have to Work with Them)" was presented by Kerry Osborne:



Tanel Põder's "Zero Slides: The Scripts and Tools which Will Make Your Life Easier and Allow You to Troubleshoot Better" was definitely a big "thumbs-up".



Dan Norris tells us how to "Avoid Common RAC Issues":



The lovely Robyn Sands presented an informative "Variance as a Tool: Measuring for Robust Performance".



Captain Morgan? Uh, I mean Ric Van Dyke tells us about "Intelligent Cursor Sharing".



Jonathan Lewis begins the first part of his presentation, "Hints on Hints".



Kyle Towle teaches us how to "Predict Oracle Performance" in his presentation:



Jonathan Lewis finishes up with the second part of his "Hints on Hints".



Last, but definitely not least, Monty Orme presents "Give 'Em What They Need!":



OK, either Gary really secretly liked the earring from his pirate costume, or someone bet him a lot of money that he wouldn't wear the earring during the Closing Ceremony. What do you think?




Enrapt crowd waiting for the Silent Auction Winner announcements:



Bah-bye! We hope to see you all next year!



Thanks to everyone (presenters, attendees, Omni Mandalay hotel staff and Hotsos teammates) who made this Sym one of the best yet!

He's ba-a-a-ack! Toon Koppelaars gives Part II of "The Helsinki Declaration" after lunch:



Below, Dave Abercrombie gives us a captivating tour of the AWR tables:



I'm sure that Bryn Llewellyn gave a very interesting talk on "Using the PL/SQL Hierarchical Performance Profiler". Such a character, he is...



Mark Williams taught us that "Instrumented Code is Better Code":



Oh! And Kerry Osborne and Stephan Haisley pulled the old switch-a-roo on the attendees just to keep them guessing. Stephan spoke about "Streams Optimization and Diagnostics".

Chris Date delivers the keynote and a bonus two technical sessions:



Wolfgang Breitling was gracious to fill-in for Joze Senegacnik. Wolfgang's presentation was entitled, Tuning by Cardinality Feedback. Thank you, Wolfgang!



Oh, no! It's Cary Millsap. Cary's presentation is called "Making Friends with the Oracle Database".



Andy Zitelli gives a great presentation entitled "Using Oracle's Extended SQL Trace Data to Quell Disputes".



Joe Johnson gave an awesome presentation (of course, we'd think so, any way!) called "Using Hotsos Tuning Techniques to Find & Fix Performance Issues: 6 Real World Examples"...and no, Joe doesn't work for Hotsos. Yet...



Karen Morton worked her magic with her presentation entitled "Managing Statistics for Optimal Performance". Karen is shown here with Flat Larry. Karen's niece sent us a Flat Stanley, and we took pictures of him in all kinds of places. When Larry Klein couldn't make it to the Sym due to a go-live, we decided to make a Flat Larry.



Gerwin Hendriksen presented "Practical Use of Method GAPP to Find Performance Bottlenecks for Business Processes in Complex Architectures".



Henry Poras gave Part 2 of his presentation from last year, entitled "Queueing Theory Analysis of Statspack Reports Obtained from Database Load Tests".

Monday was a very good day!
