Shrink Tablespace

If you start moving objects around to try and reclaim space in a tablespace there are all sorts of little traps that make it harder than you might hope to get the maximum benefit with the minimum effort.  I’ve written a couple of notes in the past about how to proceed and, more recently, one of the […]
