12c Adaptive Optimization

Since everyone seems to be all twitterpated about Oracle Database 12c this week, I thought I’d post a quick note to let you know that the slides from the presentation on 12c Adaptive Optimization I did at the Hotsos Symposium 2013 (with a lot of help from Maria) are now available in the Whitepapers / Presentations section of this blog.

While I’m on the topic, I found this little blurb in the Oracle Database 12c Release 1 New Features Guide:

Zero Effort Performance

That’s the section that talks about the Adaptive Optimization stuff. I think the documentation folks meant that they were describing performance features that didn’t require any manual intervention, but it sort of reads like the features are really easy to describe, or maybe that the writers weren’t going to work very hard on describing them. At any rate, the wording struck me as humorous. :)

  1. You were talking about normal distributed data, if you calculate statistics of n=5 and average out these 5 measure points, then the averages are distributed normal, might give too much claculation overhead.
