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

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

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

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

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

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

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

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

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

  42. Sample SQL*Loader File LOAD DATA INFILE 'APPQ.stderr' REPLACE INTO TABLE txrpt WHEN (1) = '@' FIELDS TERMINATED BY WHITESPACE TRAILING NULLCOLS (service "substr(:service,2)" -- remove leading @ ,pid ,stimestamp ":stimestamp/86400+2/24+TO_DATE('01011970','DDMMYYYY')" ,stime ":stime/100" ,queue ”’APPQ’" ,etime ":etime/100") 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 Go-Faster Consultancy Ltd.
