In 11g by default Segment creation is deferred(segments not created at time of table creation)
when you create normal tables or partition tables.
For knowing the concept of Deferred Segment Creation in 11g you can refer below note :
11.2 Database New Feature Deferred Segment Creation [Video] (Doc ID 887962.1)
Sometimes You may decide to pre-create or materialize segments for tables
that is already created in the database.
Then you can achieve that using DBMS_SPACE_ADMIN.MATERIALIZE_DEFERRED_SEGMENTS
