After reading the documents I've recommended using LOCAL, UNIFORM, AUTO as the options for tablespace management. Does anyone have any bad experiences with these? AUTOALLOCATE seems to come up with extents that are much smaller than I want and MANUAL segment management requires the use of FREELISTs (and I know that there are problems with freelists freeing up space correctly, especially in a parallel environment).

I can't find any basis for making a decision between UNDO and ROLLBACK SEGMENTS. Does anyone have any experience or recommendations about UNDO usage?

The database will be a materialize view replication of a transaction master that is being used for decision support and has a 15 minute update/refresh cycle. Basically, people can run queries against the snapshot without impacting the master.
