    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

    SQL> oradebug setmypid
    The statement has been processed.

    SQL> oradebug tracefile_name
    /u01/app/oracle/diag/rdbms/orcl/orcl/trace/orcl_ora_32505.trc
    SQL>
    SQL> oradebug dump controlf 5
    The statement has been processed.
    SQL>

    [oracle @ dhcp - cn - 10 - 182 - 210 - 9 ~] $ cat / u 01 /app/oracle/diag/rdbms/orcl/orcl/trace/orcl_ora_32505.trc | grep partition
    [oracle @ dhcp - cn - 10 - 182 - 210 - 9 ~] $
    [oracle @ dhcp - cn - 10 - 182 - 210 - 9 ~] $
    grep "PARTITION"
    [oracle @ dhcp - cn - 10 - 182 - 210 - 9 ~] $

    SQL> alter table book1 add partition p4 values ​​less than (400);

    The table has been changed.

    SQL> alter table book 1 drop partition book 1 p 1;

    The table has been changed.

    SQL> oradebug dump controlf 5
    The statement has been processed.
    SQL>

    grep "PARTITION"
    [oracle @ dhcp - cn - 10 - 182 - 210 - 9 ~] $
    [oracle @ dhcp - cn - 10 - 182 - 210 - 9 ~] $
    [oracle @ dhcp - cn - 10 - 182 - 210 - 9 ~] $ cat / u 01 /app/oracle/diag/rdbms/orcl/orcl/trace/orcl_ora_32505.trc | grep partition
