Hardware Performance testing (Oracle context)

•Goals Have a simple as possible reproducible test to estimate HW

performance Based on the test output

Evaluate if a hardware current performance corresponds to specification

Compare different HW performance Forecast application performance improvement in case of

migration to a different HW Establish a baseline in case there any suspicious that HW don't

perform as expected

•Requirements As simple as possible As close to Oracle RDBMS load as possible The same on different platforms

in case of migration to a different HW4. Establish a baseline in case there any suspicious

My experience from the field

•TESTLIO CPU & Memory Oracle Calibration Test. As simple as possible. Do exactly that DB is doing 95% of the

time. Takes 3M space, 5-20 secs to execute. Run in idle timeframe. No impact on application.

•Run TEST ..\..\..\..\..\1w\SQL\testlio.sql

•Make TEST ..\..\..\..\..\1w\sql\mktestlio.sql

NOTE: DB block size has an impact on the results

ORION (Oracle I/O Calibration Tool)•Google: orion oracle

http://www.oracle.com/technology/software/tech/orion/index.html

A single executable (Users Guide) Available for mainstream platforms

•Advantages Simple to setup & run No need to install anything (copy & run) Use the same calls as Oracle RDBMS does Can be used be used in Read Only (default) and Read Write modes Complete and Understandable results Flexible

•Disadvantages Runs against device (access to /dev/sdbx) Unreliable with NFS and FS (my experience)

ORION (Oracle I/O Calibration Tool)•FDISK

Aligning ASM Disks on Linuxhttp://www.pythian.com/news/411/aligning-asm-disks-on-linux/

•ORION echo /dev/sdb1 > ./sdb1.lun nohup ./orion_linux_x86 -run simple -testname sdb1 & ./orion_linux_x86 –help

•Theoretical IO results 1 spindle give us 100 IOPS / 50 MBPS (10)

DBMS_RESOURCE_MANAGER.CALIBRATE_IO

•Oracle I/O Calibration Tool

•11GR2 new feature Isn’t documented well

•100% DB IO Calls testing

•Overcome ORION limitations Easely can be used on any Oracle storage solution (including NFS)

•It Seams it gives relayable results

SOM Sponsors:

Disadvantages of a simple test

•Doesn’t test concurrency

•Doesn’t test different operations

•Isn’t close to your application

•Doesn’t test your application dynamic behavior

HAMMERORA

•Tool Command Language (pronounced "tickle") http://www.orafaq.com/wiki/Tcl

Tcl, or Tool Command Language (pronounced "tickle") is a simple, open-source-licensed programming language similar to Perl and PHP.

OraTCL was adopted by Oracle Corporation and is used for several of the Enterprise Manager (OEM) Event and Job scripts. OraTCL is installed with the OEM Intelligent Agent, and is thus also available for use by Oracle DBAs and developers.
