根据以往经验,这个很可能也是tab$数据被删除导致。经过分析,该库的区别是由于该库是12C的pdb
12.1.0.2


pdb

通过分析确认,确实是tab$数据被删除,通过bbed反向删除处理,实现时间完美恢复,open之后删除恶意脚本,数据库直接使用,实现完美恢复

最近有朋友反馈sql server数据库被加密格式为:.id_多位数字_.YOUR_LAST_CHANCE,让我们分析判断是否可以恢复.
YOUR_LAST_CHANCE


类似的txt文件为:
YOUR_LAST_CHANCE-2

通过分析,确定此类加密勒索病毒,我们可以实现较好的从数据库层面恢复,恢复之后基本上可以直接使用
sql-recover

如果你的数据库服务器(Oracle,sql server均可)不小心被这种病毒加密勒索,可以联系我们直接从数据库层面进行恢复

朋友公司做压力测试,awr比较异常,让给看看
1-1


这里显示数据库db time较大,数据库应该比较繁忙,主要等待事件为:library cache: mutex X
1-4

但是Load Profile显示Parses (SQL)和Hard parses (SQL)均不大
1-2

但是发现failed parse elapsed time特别大,也就是说这个库出现该问题,主要可能是由于sql语句执行解析失败导致,而解析失败最大的可能性就是sql语句语法/权限错误.对于这类问题可以通过设置event 10035进行跟踪
1-3

演示设置event 10035进行跟踪的效果

通过这里可以看出来datadg磁盘组是由rhdisk6-9 四块磁盘组成,查询相关磁盘信息发现

对比磁盘可能的损坏情况,由于在aix 平台asm disk的block有一个特征一般0082开头,通过工具打开磁盘,检索该标记对比
正常磁盘
0082-good


异常磁盘
0082-had

通过上述分析,大概评估rhdisk7 元数据部分损坏的不光是block 0和1,人工修复继续使用的可能性不太大,而且基于客户的数据库不大,采取方案是直接拷贝数据文件、redo、控制文件到文件系统,然后在本地文件系统open库
open_db

运气不错,实现完美恢复数据0丢失

对于上述的故障现象,本质原因是由于asm 磁盘组增加新磁盘之后,开始做rebalance,但是由于遭遇到 27号盘上有IO读错误,使得asm磁盘组无法正常完成rebalance,因而data磁盘组无法稳定的mount。解决该问题思路,通过patch asm磁盘组,禁止rebalance,从而使得data磁盘组不再dismount,再进行后续恢复
