一次断电引起的Oracle故障恢复-ora-600 2662故障

Posted on 2026 年 05 月 11 日 by 惜分飞

接手一个oracle恢复case,由于断电导致oracle数据库异常,现场人员进行了一系列的恢复成功,但是没有成功open库,我接手故障之后尝试做recover 报ORA-16433错误

根据经验这种错误一般是由于强制打开库失败导致,回溯oracle alert日志发现类似操作

由于无法正常recover 操作，数据库需要强制打开,考虑到之前该库open的过程有ORA-600 2662错误,这次在打开之前使用Patch_SCN调整SCN(关于Patch_SCN文章:Patch_SCN for Linux 功能完善

[oracle@xifenfei.com tmp]$ ./Patch_SCN 249756 0x205D38954E
Successfully obtained address automatically: 0x6001ae70
Original Oracle SCN at Address 0x6001ae70: 0x0
Are you sure you want to modify Oracle SCN? (yes/no): yes
New SCN at Address 0x6001ae70: 0x205d38954e
Oracle SCN successfully modified.

然后数据库顺利打开

在expdp导出数据过程中遇到了硬件错误

为了安全性采用库只读情况下exp进行导出,运气不错所有数据顺利导出,完成本次数据恢复任务

标题：Patch_SCN for Linux 功能完善

Patch_SCN工具目前有For win和for linux版本,主要用于修改Oracle SCN(特别是在oracle数据库非常规恢复中实现一键修改SCN功能,实现快速open数据库.主要解决典型问题:
ORA-600 2662
ORA-600 kclchkblk_4
ORA-600 kcbzib_kcrsds_1
最近有点空对Patch_SCN软件的for linux版本进行了完善,主要完善功能:
1. 整个代码全部通过C代码实现
2. 完善了注册机制
3. 无需输入内存地址,程序一般情况下可以直接获取地址并修改
上传软件到linux环境并授权
确保执行用户有x权限

[root@iZbp11c0qyuuo1gr7j98upZ tmp]# ls -ltr /tmp/Patch_SCN 
-rw-r--r-- 1 root root 13984 Oct 13  2025 /tmp/Patch_SCN
[root@iZbp11c0qyuuo1gr7j98upZ tmp]# chmod +x /tmp/Patch_SCN 
[root@iZbp11c0qyuuo1gr7j98upZ tmp]# ls -ltr /tmp/Patch_SCN 
-rwxr-xr-x 1 root root 13984 Oct 13  2025 /tmp/Patch_SCN

使用软件之前需要进行注册
第一次使用要求输入注册码

[root@iZbp11c0qyuuo1gr7j98upZ tmp]# ./Patch_SCN

    <address> - Memory address (entered in manual mode, hexadecimal)
    <new_value> - SCN value to modify (must be entered manually, supports decimal or hexadecimal)

Patch_SCN使用演示
软件支持自动发现内存地址和手工输入内存地址两种模式(当某些情况无法软件自动发现地址时,可以考虑人工输入地址方式进行)


###############自动识别内存地址方式修改#############################
--修改scn之前
SQL> SELECT CURRENT_SCN FROM V$DATABASE;

CURRENT_SCN
-----------
 5691132517

---进行scn修改
[oracle@iZbp11c0qyuuo1gr7j98upZ tmp]$ ./Patch_SCN 18884 5691232517
Successfully obtained address automatically: 0x6001ae70
Original Oracle SCN at Address 0x6001ae70: 0x15337ca8a
Are you sure you want to modify Oracle SCN? (yes/no): yes
New SCN at Address 0x6001ae70: 0x153395105
Oracle SCN successfully modified.

--修改scn之后
SQL> SELECT CURRENT_SCN FROM V$DATABASE;

CURRENT_SCN
-----------
 5691232520   --->由于scn会自动增加,所以比修改值稍大一点


###############手工输入内存地址方式修改########################
---当程序提示无法获取到内存地址时,采用人工输入内存地址方式进行修改
[root@iZbp11c0qyuuo1gr7j98upZ tmp]# ./Patch_SCN 18884 5691232517
Could not find valid  SCN ddress
Failed to get SCN address automatically
Please use manual address mode instead

---使用get_addr程序获取内存地址,如果无法获取联系:xifenfei
[oracle@iZbp11c0qyuuo1gr7j98upZ tmp]$ ./get_addr 
Retrieving Oracle SCN address...
Successfully retrieved SCN address: 0x6001ae70

---修改scn值
[root@iZbp11c0qyuuo1gr7j98upZ tmp]# ./Patch_SCN 18884 0x6001ae70 6691232517
Using manually provided address: 0x6001ae70
Original Oracle SCN at Address 0x6001ae70: 0x15339517f
Are you sure you want to modify Oracle SCN? (yes/no): yes
New SCN at Address 0x6001ae70: 0x18ed41b05
Oracle SCN successfully modified.

---验证修改之后scn值
SQL> SELECT CURRENT_SCN FROM V$DATABASE;

CURRENT_SCN
-----------
 6691232521  --->由于scn会自动增加,所以比修改值稍大一点
