Now that I have ascertained how the allocation and deallocation of extents in Oracle affects logging, (thanks Mohammad and Jay!) I would like to know the pro's and cons people have experienced when changing tablespaces to locally-managed rather than dictionary-managed (apart from the hassle of having to rebuild them!). Recovery of object data is not critical for the tablespaces I intend on modifying. My objective is to minimise logging and have more efficient use of space utilization - avoiding the need to coalesce tablespaces on a regular basis seems like an attractive option. I'm interested in finding out how efficient Oracle is in automatically determining extent sizes, performance benefits of having no rollback information generated and any other information (good or bad) users may have experienced on this topic.
