Partition 操作是否和 Controlfile有关？
通过实验来判断：
对比 Partition 前后的操作，看看controlfile 的dump 信息中是否有记录，
结果发现没有记录在 controlfile 中的信息。
#### Testcase-0810-1
Operations related to partition are not recorded in the control file
It is connected.
SQL> CREATE TABLE book1 (id NUMBER, val01 integer, val02 integer, val03 integer)
PARTITION BY RANGE (val 01)
(PARTITION book 1 p 1 VALUES LESS THAN (100),
PARTITION book 1 p 2 VALUES LESS THAN (200),
PARTITION book 1 p 3 VALUES LESS THAN (300)); 2 3 4 5
