从查询的信息看库异常的时候由于redo写比较频繁，后续启动上看，需要sequence 743268的日志，但是由于redo部分异常，导致无法进行完整恢复.

根据客户反馈系统运行的是9.2.0.8版本,但是服务器上面安装有10.2.0.1服务端,由于使用过10.2启动过数据库导致现在9.2.0.8无法启动.

这里很明显数据库从2009年4月开始9.2.0.1版本开始运行,然后到2015年6月18日升级到9.2.0.8版本,紧接着升级到10.2.0.1(升级8.2.0.8是为升级10.2.0.1的中间过度操作).然后这个库一直使用10.2.0.1版本运行,这次重启不知道什么原因客户以为是9.2.0.8的数据库版本,然后不管怎么样也无法启动成功(这里不知道什么原因win 服务中使用的9.2.0.8的软件,估计被人误操作了).解决该问题,就是把服务切换成10.2.0.1版本数据库正常启动.
再次提醒大家，在oracle恢复的过程中,需要仔细分析日志,日志不会骗人,不要轻信客户的现场描述

asm磁盘头全部损坏数据0丢失恢复

发表于 2017 年 4 月 20 日 由 惜分飞

接到朋友反馈说他们公司的10.2.0.4(无磁盘头备份)asm 磁盘头都损坏了，确定是被人恶意dd掉了磁盘头的1k,他通过查询发过来结果如下
asm_disk_header

分析alert日志,确定磁盘组和磁盘信息
asm mount data磁盘组报错

最后一次正常mount是使用了raw21-raw26的裸设备为data磁盘组，但是这里从DATA_002开始,表明很可能最初了两个asm disk被删除,继续分析alert日志

恢复思路
确定磁盘是只被干掉了第一个block，但是由于asm 是10.2.0.4的，没有asm disk header的备份，因此也只能自己去人工kfed修复.但是考虑到该case中所有的asm disk header 全部丢失，无任何参考，完全修复比较麻烦，另外这个库也比较小，考虑修复asm disk header 关键部位，然后通过工具直接拷贝出来数据文件，在文件系统中open库的思路.主要需要恢复磁盘头基本信息(diskname，disksize，disknum，ausize，blocksize，file directory等）
