-- List tablespaces
- space allocated
- space used
- %free (without maxbytes)
- Autoextend Y|N|Y/N
- Sum of maxbytes
- increment (in Mb) 10/100 or 0/10/.... if more than 2 datafiles with different increment size
- Largest free extent
- Space management (DICT MAN -> Dictionnary Manual| ASSM | LMTS)
- Number of files
- T: tempfile | D: datafile
- %Used (using maxbytes in calcul)
