REM Purpose:
REM	<SQLDIR_TXT>
REM	USE s_db_segs3.sql for a detailed report of segments
REM
REM	Reports SUM(bytes) for all segments by owner groupping them by
REM	the current size from dba_segments.
REM	
REM	There is a theory by which you only need 3 types
REM	of tablespaces:
REM	  160k (SMALL)
REM	  5MBm (MEDIUM)
REM	  160MB (LARGE)
REM	If you follow this theory you can use this script
REM	to "place" your segments in the "right" tablespace:
REM	  1. 160K ts (segs < 5MB)
REM	  2. 5MB ts (segs < 160MB)
REM	  3. 160MB ts (segs > 160MB)
