Tanel Poder’s Hacking Session: How Oracle SQL Plans Are Really Executed – Part 2

Tanel Poder — Thu, 14 Mar 2013 23:47:53 +0000

Here’s the Part 2 of the Oracle SQL plan execution hacking session (Part 1 is here)!

We’ll use a bit of DTracing to peek inside an Oracle SQL plan execution, plus some other random experiments. You can download the qer_trace.sh script from here. Note that this is not a “How to use DTrace” webinar, you have to learn DTrace yourself to understand (or enhance) this script.

Tanel Poder’s Hacking Session: How Oracle SQL Plans Are Really Executed – Part 1

Tanel Poder — Wed, 13 Mar 2013 14:50:13 +0000

This is the Part 1 of the hacking session I delivered live.

In this part we’ll talk mostly about how an application talks to the database session when wanting to execute a query (tracing OPI calls, fetch operations etc).

In the Part 2 (which I will upload soon) we’ll drill down inside an execution plan then.

Enjoy!

Check out this bit from my Exadata speech at the previous Enkitec E4 conference. You don’t see much of my screen output there, but if you attended my Exadata hacking session (or have watched the videos), then you’ll recognize what I’m talking about.

Tanel Poder’s Exadata Snapper Hacking session videos

Tanel Poder — Fri, 22 Feb 2013 00:04:42 +0000

Exadata Snapper (also called ExaSnapper or ExaSnap) is a new tool by Tanel Poder, which allows to “peek” into some SQL Execution-related cell metrics without leaving the Oracle database session / sqlplus prompt. The current version 0.7 is a beta version and will likely be much improved and changed once it reaches v1.0.

The tool itself will be downloadable from enkitec.com (will update this post once it’s there).

Here are the videos, split into 3 parts:

Part 1 – Introduction
Part 2 - Smart Scan and IO activity in the cell
Part 3 - Advanced Metrics and Q&A

Part 1 – Introduction

Part 2 - Smart Scan and IO activity in the cell

You can get the latest Snapper v4 BETA from here:

You can download most enkitec.tv videos also from iTunes Podcasting system and they tend to have better quality than the web version. Just subscribe to http://blip.tv/enkitectv/rss or search for EnkitecTV in the podcast directory!

Oracle Hacking Session with Tanel Poder from OakTableWorld (Oct 2012 in San Francisco)

Tanel Poder — Mon, 15 Oct 2012 18:51:09 +0000

I delivered a live Oracle hacking session at OakTableWorld in San Francisco two weeks ago and here’s the video (Thanks to Kyle Hailey & co)!

Note that this was a hacking session deliberately aimed to be fun and “hackerish” rather than useful. Do not try this in your production databases!!!

The title is “Lots of undocumented, unknown and unnecessary features in Oracle!”

You can watch it here:

Note that there are more videos available on OakTableWorld website (and probably more will show up soon!)

Enjoy!
