2 Go-Faster Consultancy Ltd.2 Agenda What is Performance Tuning? On-Line Batch What has been achieved? Questions?

3 Go-Faster Consultancy Ltd.3 Rules of Engagement If you can’t hear me - say so now! Feel free to ask on-topic questions during the presentation. This presentation (with notes) will be available on the Tech SIG page on Customer Connection and on –www.go-faster.co.uk

4 Go-Faster Consultancy Ltd.4 Who am I? DBA –Independent consultant –Performance tuning –UK Oracle User Group Unix SIG Chair www.ukoug.org

5 Go-Faster Consultancy Ltd.5 Aphorism Performance is exactly what the user perceives it to be. No more, no less. Poor performance is when the user’s perception does not match their expectation.

6 Go-Faster Consultancy Ltd.6 Aphorism Performance Tuning is a search for lost time.

7 Go-Faster Consultancy Ltd.7 Aphorism When you have eliminated the impossible, whatever remains, however improbable, must be the truth. –A Study in Scarlet, Arthur Conan-Doyle It is a capital mistake to theorise before one has data. The Memoirs of Sherlock Holmes, Arthur Conan-Doyle

8 Go-Faster Consultancy Ltd.8 Aphorism Detection is, or ought to be, an exact science. It should be be treated in the same cold and unemotional manner. –The Sign of Four, Arthur Conan-Doyle

9 Go-Faster Consultancy Ltd.9 PIA (On-Line) Performance Architecture –brief overview Sources of Metrics Graphical Techniques Tracing Techniques

10 Go-Faster Consultancy Ltd.10 It isn’t always the database! Understand architecture –Web front end –Network –Application server –Database What can you measure?

11 Go-Faster Consultancy Ltd.11 PeopleSoft Internet Architecture PIA is 4-tier architecture –Each component can contribute to response time –Need to measure each component Java Servlet (presentation logic) Java Servlet (presentation logic) Tuxedo Application Server (application logic) Tuxedo Application Server (application logic) DBMS (application data & meta- data DBMS (application data & meta- data SQL Tuxedo Message http / https

12 Go-Faster Consultancy Ltd.12 Sources of Metrics (1) Browser –Proxy Server –3rd Party software Local agent on PC Web Server –Access Log

13 Go-Faster Consultancy Ltd.13 Sources of Metrics (2) BEA/Tuxedo –Service Trace –TMADMIN Oracle Database –SQL_Trace –PSFT Application Server Trace

14 Go-Faster Consultancy Ltd.14 Hint All the data collected on a time base. Therefore, make sure that the clocks on all machines are synchronised at least with each other. –PC clocks are particularly liable to drift.

16 Go-Faster Consultancy Ltd.16 Web/Proxy Access Log Standard format for access log –www.w3.org/pub/WWW/TR/logfile.html –Apache is different

17 Go-Faster Consultancy Ltd.17 Web/Proxy Access Log Fields –Date, Time (finish not start) –Time Taken accurate to OS time units (1/100 th s or 1/1000 th s) only 1s on Apache –Message size bytes –Client IP addresses & DNS names –URI stem & Query

41 Go-Faster Consultancy Ltd.41 Graphical Analysis Don’t drown in numbers –Draw a picture Load Data into Database –SQL_Loader (Oracle 9i External Table) Process Data –Matching, Aggregation Oracle Analytic Function Load data into Excel –Draw Graph

43 Go-Faster Consultancy Ltd.43 Tips about Graphs Connect Excel directly to a database Aggregate data carefully –Too little and excel draws it badly because it adds a black border around an area –Too much and you lose details Pivot tables are useful –but Excel97 buggy Scatters and Trendlines –joining dots can obscure data –Excel supports 32000 points per series
