The CBO Panel Session for UK Oracle User Group TechFest19 has been moved from Monday to Tuesday at 16:45. I'll be chairing it, with a terrific panel of experts - but we need a few more questions in advance: jonathanlewis.wordpress.com/2019/09/13/uko…

Things I never expected to do #14: Announce the cancellation of an event due to a worldwide pandemic. OK, it's not a pandemic yet & we are determined to reschedule, but #OUG_Ireland is being delayed due to the woes of Covid-19 & concerns for our members & speakers. UK Oracle User Group 1/2

At DOAG I was asked an interesting question about real-time SPM and runaway/terminated SQL. I didn't know the answer for sure, but I do now. Scroll to the bottom of blogs.oracle.com/optimizer/post… for a new ADB demo.
