Shrink Tablespace

In a comment on my previous post on shrinking tablespaces Jason Bucata and Karsten Spang both reported problems with small objects that didn’t move to the start of the tablespace. This behaviour is inevitable with dictionary managed tablespaces (regardless of the size of the object), but I don’t think it’s likely to happen with locally managed tablespaces if they’ve been defined with uniform extent sizes. Jason’s comment made me realise, though, that I’d overlooked a feature of system allocated tablespaces that made it much harder to move objects towards the start of file. I’ve created a little demo to illustrate the point.
