The easiest way to make your query run 6-7x faster on Exadata

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.

Enjoy! ;-)

Tanel Poder’s Exadata Snapper Hacking session videos

February 22, 2013 By 1 Comment

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

Part 3 – Advanced Metrics and Q&A

Oracle full table scans, direct path reads, object level checkpoints, ORA-8103s

May 19, 2012 By 4 Comments

Here’s another hacking session video from last year:

Topics:

  • How do full table scans work?
  • How and why do the “ORA-8103: object no longer exists” errors happen
  • How does Oracle (11g) decide between a buffered full table scan and a direct path read scan (plus smart scan in Exadata)
  • What’s the difference between an object_id and data_object_id?
