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

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.
