Tools and Tips for Oracle Performance and SQL Tuning

Speaking about SQLT XPLORE – The SQLT hidden child

leave a comment »

Next week I will be participating at the East Coast Oracle Users Group ECO. If you are not familiar with this Oracle Users Group you may want to check it out. It gathers close to 300 Oracle users, and every year it gets bigger and better. The environment is friendly, and I would say even cozy. There are 6 simultaneous tracks packed into 2 full days. Sometimes it is hard to decide which session to attend, but fortunately the diversity of topics usually reduces the choice to one or two (unless you are like me, and want to learn, and learn, and learn…)

Anyways, the schedule is here so you can check what is all about. If you decide to attend this year (next week), you can still register today and get a small discount using code SPEAKERVIP.

I will be speaking about two topics. One is about Adaptive Cursor Sharing, while the second is about SQLT XPLORE, which I call “the SQLT hidden child“. SQLT XPLORE is a stand-alone module inside SQLTXPLAIN (SQLT), but it does not require SQLT to be installed. This SQLT XPLORE uses brute force analysis in order to “discover” Execution Plans that may be elusive. Typical case is when you upgrade your database and your Execution Plan changed.

Stelios Charalambides writes about SQLT XPLORE in his book “Oracle SQL Tuning with Oracle SQLTXPLAIN“. In my session at ECO I will show some XPLORE samples, and will explain how to read its output. I am planing to do a live demo about executing this tool. And of course, all questions are welcomed!

I hope to see some familiar faces next week at ECO, and also to meet some new Oracle users and other speakers. Looking forward to speak at ECO next week!
