Re: lob space - used and free

All that I can think of is DBMS_LOB.GETLENGTH. Free space would probably be total space in the tablespace minus the sum of the LOB sizes. As for benefitting from a rebuild, what would be the criteria? LOB field is usually read and written sequentially, so there aren't complicated structures that need to be rebuild, except the LOB index, which cannot be rebuilt manually AFAIK.
