database performance, sql tuning and data visualization
Thursday, October 22, 2009
for all questions on the site ashmasters.com, please asked them in the comment section on this blog post. Due to the enormously high amount of spam on that site, I am no longer responding to the posts at ashmasters.com (yes there is filter software I can set up but till I do ... )
Before working at Embarcadero I redesigned the performance pages in Oracles OEM 10g (see a before and after example). I am on the patent from the team for our tuning methodology (Patents: 20060059205) . I freely provide graphical monitoring tools such as ASHMON (TCL/TK) as well as scripts to profile database load such as S-ASH ie Simulated ASH (PLSQL). S-ASH, ASHMON and more are available at my old site http://ashmasters.com/ . I have made available C code to directly read profiling data out of Oracle's memory structures, called Direct Memory Access. I speak at conferences and give classes around the world.This blog has some of my new ideas on Visual SQL Tuning (VST), work on DB Optimizer, possibly some past material on DB performance monitoring as well as lots of references and pointers to other information on the web that I find important and worth emphasizing.
