标题：在线mv方式迁移数据文件导致数据库无法正常启动

作者：惜分飞©版权所有[未经本人同意,不得以任何形式转载,否则有进一步追究法律责任的权利.]

有客户在数据库没有关闭的情况下,直接操作系统层面mv方式把数据文件从一个分区迁移到另外一个分区,再创建ln -s(软连接)的方式实现数据文件不修改路径的方式数据文件迁移,结果数据库重启之后,库无法正常启动,报ORA-01172 ORA-01151错误

此类故障是由于在线拷贝数据文件,可能有不少最新写入的数据都有数据文件和redo不一致的风险,引起这里的ORA-600 3020最好不要通过allow N corruption的方式跳过,因为可能导致大量数据文件坏块,这样就不光丢失了redo数据,可能数据文件中好的block中的很多数据也丢失.对于这种情况,我们为了减少客户的数据丢失,选择了最少数据丢失的方法:通过bbed修改文件头,然后直接recover 数据文件,open库

2. 数据库在强制拉库的时候,很可能是屏蔽了一致性,导致文件头scn过小
3. 在resetlogs之前,先offline了83号文件,这个将导致该文件的reseltogs scn和其他文件不一致,通过Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)
20231229095533


这个库由于客户在resetlogs之前offline了数据文件,导致一些麻烦,先使用Oracle Recovery Tools修改resetlogs scn
20231229100250
然后重建ctl,修改scn,打开数据库

有客户联系我,说数据库故障经过他们一系列恢复之后,现在open库报ORA-01113 ORA-01110错误,咨询我Oracle Recovery Tools恢复工具是否可以解决该问题
ORA-01113-ORA-01110

alert日志报错

其实这个错误不是这个库不能打开的本质,一般遇到这种错误的客户,都是强制拉过库,在拉库的过程中失败,才是导致库不能open的本质原因,比如通过查看相关日志发现拉库的时候报ORA-01555 ORA-00704错

比如还有客户咨询也是ORA-01113 ORA-01110错误,希望通过Oracle Recovery Tools工具来解决该问题,通过咨询客户确认他们其实是在前期恢复中报ORA-600 2662错误
ORA-600-2662

对于一般通过强制拉库启动过程中报ORA-600错误,后面恢复中报ORA-01113 ORA-01110错误无法正常open的库,一般不用Oracle Recovery Tools工具来解决,通过一些恢复技巧就可以解决该问题.如果无法自行解决,可以联系我们进行技术支持,最大限度抢救和数据,减少损失

8个节点的rac,有一个节点有点问题,重装系统的时候,没有选择任何磁盘
20231221191215

结果发现该机器上的所有磁盘都被分区并且加入到centos的vg中了,导致另外7个节点的asm disk的所有磁盘全部异常,磁盘组无法正常mount,在以前正常的rac节点上pvs扫描发现如下结果
20231221191551
对原asm disk(现在被分区加入到vg中的磁盘)进行分析发现所有的ssd磁盘被的以前记录被置空,机械磁盘的数据正常,机械磁盘kfed看到的记录

出现该问题是由于ssd盘的trim操作导致,相关知识补充:TRIM(SATA), Deallocate(NVMe), UNMAP(SCSI)指的是同一类指令，都是为了减少不必要的数据搬移。
原因：
在文件系统中，删除文件并没有真正的删除物理的数据，只是清空了记录表。而此时，对SSD来说，它并不知道文件已经被删除了，只有下次覆写的时候，SSD才能发现之前被删除的文件对应的page是无效的，从而启动GC。然而，如果在此之前发生了GC等数据搬移动作，无效的page仍然会被当做是有效的。重新磁盘分区,重建文件系统也可能触发类似操作
作用：
Trim 只是一个指令，它让操作系统通知 SSD 主控某个页的数据已经‘无效’后，任务就已完成，并没有更多的操作。TRIM 的先进性在于它可以让固态硬盘在进行垃圾回收的时候跳过移动无用数据的过程，从而不再用重新写入这些无用的数据，达到节省时间的目的。

标题：kettle导致MySQL数据丢失恢复

有客户通过kettle 插入数据，由于配置不当导致原数据丢失,希望能够恢复之前数据（mysql数据库）
20231217125043

通过分析（相关文件的时间）,判断kettle应该是在插入数据之前触发了truncate操作导致数据丢失,而且还插入了部分数据

通过数据块层面扫描分析,找出来需要恢复表对应的page文件
20231217125854
解析这些page文件恢复出来客户需要数据
20231217130029
遇到此类误操作,最重要的是保护现场,尽可能减少对数据文件所在分区的写入操作,可以实现最大限度数据恢复.
