Charlie, that's the point of the locally managed tablespaces: the extent size is determined by the tablespace, not by the DBA. If your locally managed tablespace is declared as "AUTOALLOCATE", then the next extent will depend on what you already have. The minimum extent size will range from 64k to 512M, all sizes being the powers of 2. If the extent size is fixed, that there is no choice.
