I chose to talk about a technique I used at a client’s site to report the topmost space-wasting objects in an Oracle database. I was looking for a way to detect these objects without having to run some expensive analyze statements or dbms_stats jobs. I found out that I can use the dbms_space package to do this. It worked very well for me and I’m sure lots of DBAs could use this technique too.
Number 10? I only just finished Dirty Dozen #1. What’s going on here, then? Well, no one said I had to write them in any particular order! But, if you look at the posters, they are clearly numbered. Should someone else pick up the Dirty Dozen challenge, it will help them to see which ones…
I first presented on Oracle 10g Block Change Tracking Internals at UKOUG 06 in Birmingham. It was very well received, but there were quite a few gaps in my knowledge, and I later discovered I was incorrect in some places. I’ve done some additional research, filled in the blanks and corrected in a few places. Download it here.
Looks like our blog has turned into a MySQL blog over this week, so I have to do something about it. Luckily, I have zillions of pending posts, so I’ll start with posting my presentations materials from this conference with my remarks on how it went in general.
Beth Breidenbach, having braved a week thick with posts from the MySQL Conference, has published the 42nd edition of Log Buffer, the weekly review of database blogs, on Confessions of a database geek.
We are assisting one of our clients with a data conversion project and have used a feature that I was surprised so few people knew about. It is the multi-table insert.
Day three at MySQL Conference 2007
Starting out bright and early again. I have a feeling Martin and Yannick might gang up on me for waking them up so early every morning and making sure we are on our way at 7am sharp, but it’s worth it. We did make it here for the keynotes.
It seems Google couldn’t wait to have their code evaluated for merging into the main source tree, and decided to release it to the general public as patches to 4.0.26 for the community to evaluate. What have we added and enhanced?
My presentation went well, I had a packed room, no standing room either. It is quite interesting that in spite of the fact that there have been a few tuning presentations already, there’s still interest in more. A quick question revealed the room was quite evenly split between DBAs and Developers..
