Dear reader,
thank you for your interest in Expert Oracle Exadata, 2nd edition.
Throughout the book you witnessed a pleathora of useful diagnostic
scripts. While the contents of many was shown in the body of the book,
some of them are lengthy enough that we decided not to print their
contents in the listings and rather include them here.
Please make sure to refer to the book for more information and context
of these scripts! Always consult the official Oracle documentation.
Before you start using _any_ of these scripts:
- You must understand what the script you are about to use actually does
(including any effects)
- You must ensure that you are in compliance with Oracle licensing
- You have to test the script thoroughly in a development environment first
Although great care has been taken by the authors, it is your
responsibility to remain in compliance with Oracle licensing, your
environment's standards, procedures and change control.
Have fun!

-- File name: fsx.sql
--
-- Purpose: Find SQL and report whether it was Offloaded and % of I/O saved.
--
-- Author: Kerry Osborne
--
-- Usage: This scripts prompts for two values.
--
-- sql_text: a piece of a SQL statement like %select col1, col2 from skew%
--
-- sql_id: the sql_id of the statement if you know it (leave blank to ignore)
--
-- Description:
--
-- This script can be used to locate statements in the shared pool and
-- determine whether they have been executed via Smart Scans.
--
-- It is based on the observation that the IO_CELL_OFFLOAD_ELIGIBLE_BYTES
-- column in V$SQL is only greater than 0 when a statement is executed
-- using a Smart Scan. The IO_SAVED_% column attempts to show the ratio of
-- of data received from the storage cells to the actual amount of data
-- that would have had to be retrieved on non-Exadata storage. Note that
-- as of 11.2.0.2, there are issues calculating this value with some queries.
--
-- Note that the AVG_ETIME will not be acurate for parallel queries. The
-- ELAPSED_TIME column contains the sum of all parallel slaves. So the
-- script divides the value by the number of PX slaves used which gives an
-- approximation.
--
-- Note also that if parallel slaves are spread across multiple nodes on
-- a RAC database the PX_SERVERS_EXECUTIONS column will not be set.
--
-- See kerryosborne.oracle-guy.com for additional information.
