1) Pctfree and pctused are not storage parameters. 2) Oracle allows using both of those parameters as shown by the next example:
SQL> select tablespace_name from dba_tablespaces 2 where segment_space_management='AUTO'; TABLESPACE_NAME ------------------------------ CWMLITE DRSYS EXAMPLE INDX ODM TOOLS USERS XDB COMPLIANCE VIEWS 10 rows selected. SQL> set termout on SQL> set echo on SQL> @/tmp/1 SQL> create table 2 test_table 3 (c1 number) 4 tablespace 5 compliance 6 pctfree 20 pctused 30 7 / Table created. SQL> 3) I have no idea who the "guru" is, but he or she hasn't been following this list. There was quite an extensive debate about ASSM not so long ago, resolved by Tanel Poder's detailed presentation of the new bitmap mechanism.
