The first time or 2 that it is parsed following an instance start, it chooses a bad plan. Shortly thereafter it will start choosing a different (better) plan. What factors could cause this behavior? The stats have not changed, nor have the system stats. I have 10053 traces for both the good and bad plans. Is this an ok forum to ask such a question? I've had an SR open for more than 2 months with no valuable suggestions to show for it.dbajackhttps://www.blogger.com/profile/17744173618686753649noreply@blogger.comtag:blogger.com,1999:blog-3086558868352622884.post-65563329730650612172007-12-09T21:34:00.000-08:002007-12-09T21:34:00.000-08:00Excellent job guys, looking forward for more posts...Excellent job guys, looking forward for more posts<BR/>Malak AzizAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-3086558868352622884.post-57952710230255547862007-12-09T01:11:00.000-08:002007-12-09T01:11:00.000-08:00hi there,I really liked the post.Going to add it m...hi there,<BR/>I really liked the post.Going to add it my blogroll,site.Hope I shall learn alot about my optimizer.<BR/>Keep the good posts coming.<BR/>Cheers,<BR/>Aman....Aman....https://www.blogger.com/profile/03468684193635458317noreply@blogger.comtag:blogger.com,1999:blog-3086558868352622884.post-52536705204202989492007-12-07T12:34:00.000-08:002007-12-07T12:34:00.000-08:00Wonderful!
