Reporting Space-Wasting Objects in Oracle

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.

MySQL Conference 2007 1.2

My presentation went well, I had a packed room, no standing room either.
