Welcome to my blog on Oracle SQL Tuning!

The views expressed on this blog are my own and do not necessarily reflect the views of Oracle.

It has been a while since I first thought on starting a blog on Oracle SQL Tuning. Over the past decade or so I have accumulated a lot of practical knowledge in this interesting area. Even when I keep sharing this knowledge with my fellow co-workers at Oracle, I always feel like I should expand my horizon to the larger community who is out there, dealing the same kind of issues that I do, re-discovering the hard way many things that we already know.

After an enlightening moment while participating as a speaker at the awesome Hotsos Symposium 2012, I decided to open up and reach out. I have been learning from others through their valuable blogs. Now it is time to pay back, and share with whoever is interested in Oracle SQL Tuning, whatever I have learned over the years.

Nothing that I post is Oracle confidential. I blog about what I have learned through others, through my own experience, and through carefully crafted test models that demonstrate how things actually work. I also blog about the tools that I have created over the years, and which I have made available to the Oracle community through My Oracle Support (MOS).

This place is a a friendly place. If you come here, I hope it is because you want to learn something new in the area of SQL Tuning, or you want to share something you learned. I will make mistakes, and I expect you to let me know if what I write seems to be wrong. I do my best to minimize the number of mistakes that I make, but I am far from perfect. I always welcome feed-back.

With all that said, I truly welcome you to this place.

Cheers — Carlos Sierra

  2. Hi Carlos,
    Thanks for than the performancec tuning book you are writing. It’s really good. But Can you post us how to download the sqlt and the URL. The one which shown in the blog is not working. Also Can you complete the chapter 17 , so we can install the SQLT and then be able to practise the same.
