We aren't sure WHAT is the discrepancy that you see -- whether it relates to specific types of segments or depends on extent sizes.

Hi everybody: I am running oracle 10.2.0.3 and it looks like the data in dba_extents and dba_segmetns views are not consistent. When I aggregate them on a owner level (select owner, sum(bytes/1024)/1024 from dba_???) the results from dba_extents seem to be different from dba_segments. I have opened an SR with Oracle a week ago and so far got nothing. Gene Gurevich
