Optimizer, Hyperion, OS, EBS


Over at the Inside the Oracle Optimizer blog we have a discussion of Understanding DBMS_STATS.SET_*_PREFS procedures. Always informative and useful. This blog is from the folks who work on the optimizer. You can't find a better source for information on the subject out there.


Consistently good stuff coming from the In 2 Hyperion blog. Two items this week:

Users Can Improve Essbase Reporting Performance (and no, they do not mean the users can improve performance by just going home and leaving the servers alone. Anybody can tune a system without users, it's getting paid for supporting no-user systems that's the trick).

and Sparse, Dense, and Blocks For Dummies, though of course our readers aren't dummies, so you can give that article to a friend to read.

Computing: New OS Kernel Fully Proven

Slashdot is reporting on a new microkernal called L4 that is fully mathematically proven. Sounds like a good line of research. Imagining a world where your OS never fails and never lets your applications misbehave is very nice. Hate to be a pessimist, but if the new systems are created by humans they are still going to have problems crop up, just less of them, hopefully. There is a philosophical view that I find attractive that posits that the universe remains in motion, moving from that which is crude to that which is refined precisely because everything in it has imperfections. there is no such thing as a perfect diamond crystal, for instance. Perfection is stasis, thus life is imperfect. Yes, 'life is imperfect' is definitely an understatement at times, but that's another story.


Another big set of updates this week over at the Oracle E-Business Suite Technology blog:
