There is a quote from a fantastic 1950’s B movie “It Came from Outer Space”, part written by the legendary Ray Bradbury, that has stuck with me since I first saw it as a child:

We lost Douglas Adams 25 years ago today. This has made a lot of people very sad and has been widely regarded as a bad move.
Maybe just adjusting statistics to use indexes just isn't enough. For huge performance gains, you might want to consider clustering the actual data (if you can). Have another blog post. chandlerdba.com/2026/05/08/p...
Performance: Clustering Data
In my previous post I spoke about using TABLE_CACHED_BLOCKS to make the CLUSTERING_FACTOR for indexes more realistic by having Oracle assume there was more than 1 block from the table in the buffer…

I recently wrote a block post, which was popular. So here's another one. A bit about performance and using indexes this time. Well, really it's about setting TABLE_CACHED_BLOCKS, given that most of you kids out there still don't. Understand what it means, and set it! chandlerdba.com/2026/05/06/p...

Oracle Transparent Hugepages
I have only just found out (thanks Sascha) that Oracle has changed its stance on transparent hugepages, depending upon which linux kernel you are using. If you are using UEK7 (basically, Oracle Lin…

I've decided to shut down verifiedbsky.net. While there was quite a bit of interest early, that has basically completely died down and it took some effort to keep the service alive. It was fun, I learned a lot, but it doesn't make sense anymore. Thanks to everyone who used and supported it!
