It’s time for another exciting installment of Log Buffer, the weekly review of database blogs.
Today I’ve been trying to reproduce in an 11g database one of the problems I faced with 10g—one on those problems Riyaj described in his Multi-Column Correlation and Extended Stats in Oracle 11g post. And the fun part is that I wasn’t able to reproduce it. Yet just setting optimizer_features_enable=’10.2.0.4′ made it show up again.

I recently traveled to Europe to present at a few conferences. The Slovenia Oracle User Group (SIOUG) conducted an Oracle conference in Portoroz, a port city in Adriatic Sea. Back to reality. I presented a few papers for the Dallas Oracle Users Group (DOUG) for their October tech meeting too. All these papers can be accessed following these links…Also, if you are planning to attend the UKOUG Conference & Exhibition in December, please attend my presentation on “Cost based query transformation” on Thursday of that week.
