[Oracle][Partition][Controlfile]Partition 操作是否和 Controlfile有关？-优快云博客

本文通过实验验证了在Oracle数据库中，表的分区操作并不会记录到控制文件中。实验包括创建分区表、添加分区及删除分区等操作，并检查控制文件的dump信息，确认这些操作不会被记录。

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
