SQLSat76 | TroubleshootingSQL

I just concluded my presentation on “Debugging the Deadlock for the Scheduler” at SQL Saturday 76 over a Lync meeting. The WiFi and Lync gods decided to be benevolent today and let me present without an untoward incident! As always it was fun to demonstrate the use of a debugger… Winking smile The attempt of the presentation was to demonstrate what can be done proactively and reactively when dealing with a deadlocked schedulers condition.

A special thank you is due to all the sponsors without whom the event today wouldn’t have been possible: Microsoft New Zealand, RedGate, SQL Pass, New Zealand MS Communities and SQL Services!

The slide deck used for presentation today is available on Slide Share and is embedded below:

The demo files used are available at SkyDrive in the file SQLSat76_Demo.zip The walkthrough for the debugging that I explained along with the use of the Powershell script to automatically collect DMV outputs based on messages in the Windows Application event log are available using the posts available under the walkthroughs link below as well as the zip file mentioned above.

And last but not the least, a big Thank You to Dave [Twitter | Blog] for helping arrange all the logistics so that I could present and also for giving me this opportunity!

I am quite excited about this Saturday (January 28th, 2012) which will witness SQL Saturday #76 being organized at Auckland. This time around I will not be physically present for the event but will be presenting via Live Meeting on “Debugging the deadlock for the scheduler”. It would have been awesome to be there in person but I shall make the most of the remote opportunity! As they say… If wishes were horses, even beggars would ride! I am going to show you some cool stuff that you can do when you encounter a Deadlocked Schedulers scenario in SQL Server including a demo on debugging a SQL dump!

There are a bunch of other interesting sessions on a whole gamut of topics for you to pick and choose from! Space is limited so if you want to attend and be part of the fun and learning, then get yourself registered here pronto. The list of sessions that for the day are available here.

Venue: Microsoft New Zealand, Level 5, 22 Viaduct Harbour Ave, Auckland CBD
Date: January 28th, 2012
Time: Registration opens at 8.30AM NZ time | Event will conclude around 5PM NZ time

Looking forward to another fun-filled Saturday! Winking smile
