Carlos Sierra's Tools and Tips

I am delivering a two-days SQL Tuning Workshop at the Norther California Oracle Users Group (NoCOUG) in Pleasanton, California. Today is the 2nd and last day of this class. We discussed yesterday: Cost-based Optimizer (CBO) Statistics, Event 10053, Adaptive Cursor Sharing (ACS) and SQL Plan Management (SPM). We will discuss today some SQL Tuning tools: Event 10046, Trace Analyzer TRCANLZR, SQLTXPLAIN (SQLT), SQL Health-Check (SQLHC) and SQLT Test Case (TC). There are around 35 participants and I would say the level of the class is between intermediate to advanced. Most participants are seasoned DBAs and some have a good level of expertise as Developers. Abel Macias is participating in this session as my co-instructor. He is bringing to class his extensive expertise in SQL Tuning. It is always a challenge to keep the attention of such a large and diverse group, but I would say the level of participation has been quite high. I appreciate all the effort from several contributors of the NoCOUG who have made this training possible. My special thanks to Gwen Shapira, Randy Samberg, Iggy Fernandez and Eric Hutchinson. It is very rewarding to see how Oracle Users Groups are putting together events like this where we can openly share knowledge with our Oracle users community.

I will speak at the actual NoCOUG Conference this Thursday. I will talk about the content of SQLTXPLAIN (SQLT) main report, which is quite comprehensive. I will go over some samples and I will allocate plenty of time for questions during and after my presentation. These days SQLT is widely used within Oracle and now by several enterprise Oracle customers.

Stelios Charalambides book about SQLT Tuning and SQLTXPLAIN will be released on March 20. The title is Oracle SQL Tuning with Oracle SQLTXPLAIN. This book can now be pre-ordered in Amazon. If you want to learn more about how to use SQLTXPLAIN to diagnose SQL Tuning issues you may want to get a copy of this book.

After NoCOUG I will spend one week at the office, where I will deliver a live Webinar in SQL Tuning to our Oracle Partners. Then my next conference is the popular Hotsos Symposium in March 3-7. In my humble opinion, this annual Hotsos event is the single most relevant in the area of Oracle Performance. Thus I am very excited to have the opportunity to speak there. A real honor!
