Most of the operational perform...Thank you Darryl.<br /><br />Most of the operational performance talent that I know within Oracle Corporation are people who consider themselves DBAs, who work in teams that tend to visit clients in post-production situations. I don't think that's Oracle's <i>intent</i> as much as it's just not until after trying to go live that Oracle customers themselves tend to pay any attention to performance. That's because it's only then that clients have enough information to discover that they have performance problems.<br /><br />At the best-run projects I know about, the product development teams have their own DBAs. These are DBAs who are focused on the development process and who have no operational responsibilities to other projects (although they may follow the applications they've helped to build into production).<br /><br />I'm speaking at <a href="http://www.kscope11.com" rel="nofollow">Kscope 11</a> this week about my appreciation for Agile software development methods. There's also a recording of a webcast presentation I did last week, which you can find at <a href="http://www.red-gate.com/products/oracle-development/deployment-suite-for-oracle/webinars/webinar-cary-millsap-agile" rel="nofollow">Red Gate Software's web site</a>. Two other sessions to look for are Ron Crisco's "Data design for developers—a primer," and Dominic Delmolino's "Is your performance feedback loop a racetrack or a noose?"<br /><br />I agree wholeheartedly with your final paragraph: "If more informative tools were available to designers, better, faster 'feedback' would be obtainable." That sentiment is the motive for <a href="http://method-r.com" rel="nofollow">my company's</a> focus on bringing feedback about response time and throughput more elegantly and less expensively into the early phases of software development projects.Cary Millsaphttps://www.blogger.com/profile/16697498718050285274noreply@blogger.comtag:blogger.com,1999:blog-2954359812249072053.post-280243279781203262011-06-26T12:16:48.968-05:002011-06-26T12:16:48.968-05:00Nice post, well written.

I, however, agree with your perception on the matter. Better informed design = better results. <br /><br />I'd like to mention that Agile design seems like a great idea (I've not used it, yet), but that the "feedback" step may put too much requirement on the DBA for performance measurements, if the DBA is heavily charged with operational support issues.<br /><br />If more informative tools were available to designers, better, faster "feedback" would be obtainable.Darryl Griffithshttps://www.blogger.com/profile/14606963192602668739noreply@blogger.comtag:blogger.com,1999:blog-2954359812249072053.post-51058875164248816342011-06-09T19:37:00.270-05:002011-06-09T19:37:00.270-05:00I remember being taught Operations Researchinclude...I remember being taught <a href="http://en.wikipedia.org/wiki/Operations_research" rel="nofollow">Operations Research</a>included performance tuning, 30 years ago. I went on a tour of a large oil company data center, all star-trekky inside huge blast doors, with a little pdp off to the side, which immediately caught my interest as that was what I was working on at the time. When I asked, the fellow said they used it to watch and probe network load between the supercomputer centers.<br /><br />word: exifierJoel Garryhttps://www.blogger.com/profile/13325061229393838224noreply@blogger.com
