Question Time

Filed under: Oracle — Jonathan Lewis @ 7:15 pm BST Oct 19,2017

It’s that time of year again – the UKOUG Tech conference is approaching and I’ve organised a panel session on the Cost Based Optimizer.

This year I’ve got Christian Antognini, Nigel Bayliss, Maria Colgan and special guest star, all the way from Australia, Richard Foote on the panel, with Neil Chandler and Martin Widlake taking on their inimitable role of MCs.

If you’ve got any questions you’d like to put to the panel, you will have a chance to write them down on the day, but it would be nice to have a few supplied in advance in the comment below.  Tactical, strategic, technical, or just plain curious – this is a panel that can tell you what can be done, what shouldn’t be done, and how to do the things you shouldn’t do but sometimes have to.

If you prefer to email your questions then click this link.

Latest thought – a tweet would be a nicely sized question – if you want to reply to this one.

  1. Why doesn’t Oracle gather chain_cnt statistics when gathering stats. It should be pretty easy now that it uses a 100% sample for everything else.
