Below is the most complete tablespace script I have found. I think you will like it.

set pagesize 80 linesize 100 feedback off column tablespace_name heading Tablespace format a19 column object_count heading 'Objects|(#)' format 999990 column mb heading Mb format 9990
column sum(frags) heading 'Frags|(#)' format 9999 column avail heading 'Max|(Mb)' format 9999.99 column free heading 'Free|(%)' format 999.9

column bytesize heading 'Size|(Mb)' format 9999999
column byteused heading 'Used|(Mb)' format 9999990
column bytefree heading 'Free|(Mb)' format 9999999
column init_ext heading 'Initial|(K)' format 999999
column next_ext heading 'Next|(K)' format 999999

Here is one that I use. I do not count the TEMP tablespace and the RBS tablespace because these vary in size.

SELECT sum(bytes) DB_SIZE from dba_segments where tablespace_name not in ('RBS','TMP')

You can do more math if you do not want the answer in bytes.

Ruth
