oracle – The creation of deferred segment ORA-14224 is not supported for this schema

I'm trying to use the delayed segment creation without success.

My deferred_segment_creation parameter is set to TRUE, but the new tables do not differ. I've also tried explicitly to specify SEGMENT CREATION DEFERRED in my create table statement but getting the following error:

CREATE TABLE NEWTABLE3 (number n1) SEGMENT CREATING MYTBS DIFFERENT TABLESPACE
*
ERROR at line 1:
ORA-14224: Deferred Segment creation is not supported for this schema

Can any one provide hints about what I'm doing wrong?

Thank you!
