通过询问知道由于file#=17最初由于裸设备权限异常,导致无法访问,执行了delete from file$ where file#=17,然后遭遇异常又人工插入了一条file#=17的记录到file$中,但是由于不知道具体值,可能是由于部分值插入错误引起现在问题.
20190927225858

通过分析file$表定义

create table file$                                             /* file table */
( file#         number not null,                   /* file identifier number */
  status$       number not null,                      /* status (see KTS.H): */
                                               /* 1 = INVALID, 2 = AVAILABLE */
  blocks        number not null,                   /* size of file in blocks */
                                           /* zero for bitmapped tablespaces */
  ts#           number,                         /* tablespace that owns file */
  relfile#      number,                              /* relative file number */
  maxextend     number,                                 /* maximum file size */
  inc           number,                                  /* increment amount */
  crscnwrp      number,                                 /* creation SCN wrap */
  crscnbas      number,                                 /* creation SCN base */
  ownerinstance varchar("M_IDEN"),                    /* Owner instance name */
  spare1        number,      /* tablespace-relative DBA of space file header */
                                   /* NULL for dictionary-mapped tablespaces */
  spare2        number,
  spare3        varchar2(1000),
  spare4        date
)

通过dump文件头(文件创建大小/SCN等),结合一些计算和经验值,获取到相关值重新插入正确值,一切恢复正常

delete from file$ where file#=17 and ts#=384;
insert into sys.file$ (FILE#, STATUS$, BLOCKS, TS#, RELFILE#, MAXEXTEND, INC,
 CRSCNWRP, CRSCNBAS, OWNERINSTANCE, SPARE1, SPARE2, SPARE3, SPARE4)
values (17,2,256000,384,17,0,0,3087,1631091037,null,71303170, null, null, null);
commit;

再次提醒,file$中记录请勿人工修改,以前写过相关casefile$ 删除记录恢复(delete file$ recovery)

这个客户比较幸运,asm disk被格式化之后,没有进行任何写操作,理解对现场进行了保护,没有任何的二次破坏.因为处理过多起类似故障(oracle asm disk格式化恢复—格式化为ntfs文件系统,oracle asm disk格式化恢复—格式化为ext4文件系统又一例asm格式化文件系统恢复),有一定的经验,一般三种方案恢复数据文件：
1)运气好直接通过kfed进行修复asm disk,然后mount起来,然后把数据文件拷贝到文件系统中
2)通过相关工具把asm disk中相关的数据文件拷贝到文件系统中
3)如果损坏的严重,通过底层碎片,把相关数据文件恢复到文件系统中
拷贝完成数据文件之后,然后根据文件的情况有几种可能性:
1)直接open数据库,处理可能的其他坏块
2)通过一些方法强制拉库,然后对其进行导出导入新库
3)通过工具直接恢复表数据,甚至恢复部分核心数据
这次的恢复运气不错,对asm disk进行一系列修复之后,asm 磁盘组mount成功

这次运气非常好,该文件也只有一个坏块,整体来说,把正在运行的asm disk磁盘格式化为ntfs格式化,整个数据库文件只发现一个坏块.拷贝数据文件,redo,ctl等之后

通过重建控制文件尝试open数据库

通过dba_extents 定位坏块对象,然后根据实际情况处理(index直接rebuild,表跳过,lob置空等方法),确定数据没有问题,重建磁盘组,数据回迁,恢复完美完成

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

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
asm-foreign

这里确定rhdisk7磁盘异常，通过kfed分析磁盘情况

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

这里比较明显数据库在查询user$中的SYS用户的时候,无法查询数据从而出现ORA-00600: internal error code, arguments: [kokasgi1]错误.通过进一步对USER$表进行分析发现,sys和system被人重命名

SQL> select name from user$ WHERE NAME LIKE 'SYS%';
NAME
------------------------------
SYSDW
SYSMAN
SYSTEMDW

定位到具体问题,解决比较简单,在oracle的open过程中,通过对user$表进行修复,实现数据库完美恢复.

mos相关记录
参考:ORA-600 [KFRVALACD30] in ASM (Doc ID 2123013.1)
kfrValAcd30-mos

ORA-00600: internal error code, arguments: [kfrValAcd30]可能是bug或者硬件故障导致.基于客户的情况,最大可能就是由于硬件故障导致asm 磁盘组的acd无法正常进行,从而无法mount成功.如果运气好,通过kfed相关修复可以正常mount成功,运气不好可以通过底层进行恢复数据文件,从而最大限度恢复数据.

报错比较多，客户还反馈登录数据库之后，发现所有的表都丢失。第一反应可能数据字典损坏了，然后让客户查看备库，现在dg的备库也一样表都丢失了，进一步确认字典可能异常，让客户提供system文件进行本地分析.发现DBMS_SUPPORT_DBMONITOR触发器调用DBMS_SUPPORT_DBMONITORP存储过程,和警告：互联网中有oracle介质被注入恶意程序导致—ORA-600 16703中的名称非常类似,但是有点不一样,以前的恶意脚本中都是被注入并且触发之后，数据库无法正常启动，这次数据库能够正常open成功.分析恶意脚本,确认原因
1
2
3
确实这次的恶意脚本是在2016年8月份被创建在库中,在600天之后重启被触发,而且是删除非sys的tab$中记录.知道了恶意脚本的源头,那恢复就比较容易,直接通过批量bbed程序对tab$反删除可以实现比较完美恢复.原则上这样的故障可以实现数据库完美恢复,原库继续使用.
