You cannot specify BITMAP when creating a global partitioned index. You cannot If index is locally partitioned, then table must be partitioned. If table is If you omit this clause, then Oracle Database sets PCTFREE to 10 and INITRANS to 2. You cannot specify BITMAP when creating a global partitioned index.
