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.

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

Physically Addressed Metadata Redundancy on 12c ASM ( PHYS_META_REPLICATED )

从版本12.1开始，ASM会对某些物理元数据做一份复制，具体的说是每个磁盘的第一个AU（0号AU）上元数据。这意味着，ASM同时维护着两份磁盘头、FST（Free Space Table）表、AT（Allocation table）表的数据。需要注意的是ASM对这些数据采用的是复制（replicate），而不是镜像（mirror）。ASM镜像（mirror）意味着把一份数据，拷贝到不同磁盘上；而物理元数据的副本位于相同的磁盘，因此使用的术语复制（replicate）。这意味着在external冗余的磁盘组中，物理元数据也会被复制。PST也是物理元数据，但是ASM是通过镜像，而不是复制来提供数据保护。因此只有在normal和high冗余的磁盘组中，PST表存在数据的冗余。物理元数据位于每块ASM磁盘的0号AU。元数据复制的特性打开后，ASM会把0号AU的内容拷贝到11号AU，然后同时维护这两份副本。创建磁盘组时如果指定或修改了一个已经存在的磁盘组的compatibility属性为12.1及以上，该特性会自动被打开。当提升ASM compatibility属性值为12.1及以上时，如果11号AU有数据，ASM将把这些数据移动到别处，然后将物理元数据复制到11号AU。从版本11.1.0.7开始，ASM在1号AU的倒数第二个块维护了一份磁盘头的副本。在版本12.1中，ASM仍然维护着这个副本数据。也就是说，现在每个ASM磁盘，有磁盘头的三个副本。

查看xifenfei磁盘组属性

[grid@localhost ~]$ asmcmd lsattr -l -G XIFENFEI

access_control.enabled   FALSE
access_control.umask     066

cell.smart_scan_capable  FALSE

compatible.rdbms         10.1.0.0.0
disk_repair_time         3.6h
idp.boundary             auto
idp.type                 dynamic
sector_size              512

这里可以看到目前compatible.asm为11.2,没有phys_meta_replicated属性

查看磁盘头信息
ASM磁盘头的fdhdb.flags条目指代了物理元数据的复制状态：
· kfdhdb.flags = 0 — 元数据没有复制
· kfdhdb.flags = 1 — 元数据已经复制完毕
· kfdhdb.flags = 2 — 元数据在复制过程中

[grid@localhost ~]$ for disk in `asmcmd lsdsk -G XIFENFEI --suppressheader`;
> do kfed read $disk | egrep "dskname|flags"; done
kfdhdb.dskname:           XIFENFEI_0000 ; 0x028: length=13
kfdhdb.flags:                         0 ; 0x0fc: 0x00000000
kfdhdb.dskname:           XIFENFEI_0001 ; 0x028: length=13
kfdhdb.flags:                         0 ; 0x0fc: 0x00000000
[grid@localhost ~]$ kfed read /dev/xifenfei-sdg|grep kfbh.type
kfbh.type:                            1 ; 0x002: KFBTYP_DISKHEAD
[grid@localhost ~]$ kfed read /dev/xifenfei-sdg aun=11|grep kfbh.type
kfbh.type:                            8 ; 0x002: KFBTYP_CHNGDIR
[grid@localhost ~]$ kfed read /dev/xifenfei-sdg blkn=254 aun=1|grep kfbh.type
kfbh.type:                            1 ; 0x002: KFBTYP_DISKHEAD

这里也比较明显,在aun 11的位置没有第一个au的备份
修改compatible.asm为12.2

[grid@localhost ~]$  asmcmd setattr -G XIFENFEI compatible.asm 12.2.0.0.0
[grid@localhost ~]$ asmcmd lsattr -l -G XIFENFEI
Name                        Value

cell.smart_scan_capable     FALSE
cell.sparse_dg              allnonsparse
compatible.asm              12.2.0.0.0
compatible.rdbms            10.1.0.0.0

idp.boundary                auto
idp.type                    dynamic
logical_sector_size         512
phys_meta_replicated        true
preferred_read.enabled      FALSE
scrub_async_limit           1
scrub_metadata.enabled      FALSE
sector_size                 512
thin_provisioned            FALSE

这里可以看到修改为compatible.asm=12.2之后，出现phys_meta_replicated属性

查看au的备份

[grid@localhost ~]$ for disk in `asmcmd lsdsk -G XIFENFEI --suppressheader`;
> do kfed read $disk | egrep "dskname|flags"; done
kfdhdb.dskname:           XIFENFEI_0000 ; 0x028: length=13
kfdhdb.flags:                         1 ; 0x0fc: 0x00000001
kfdhdb.dskname:           XIFENFEI_0001 ; 0x028: length=13
kfdhdb.flags:                         1 ; 0x0fc: 0x00000001
[grid@localhost ~]$ kfed read /dev/xifenfei-sdg aun=11|grep kfbh.type
kfbh.type:                            1 ; 0x002: KFBTYP_DISKHEAD
[grid@localhost ~]$ kfed read /dev/xifenfei-sdg blkn=254 aun=1|grep kfbh.type
kfbh.type:                            1 ; 0x002: KFBTYP_DISKHEAD
[grid@localhost ~]$ kfed read /dev/xifenfei-sdg|grep kfbh.type
kfbh.type:                            1 ; 0x002: KFBTYP_DISKHEAD

这里就可以看到kfdhdb.flags为1，在au 11的地方也变为了磁盘头信息

很明显由于xifenfei-sdg第一个au 已经被完全dd掉，xifenfei磁盘组无法mount，提示ORA-15040: diskgroup is incomplete

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）

impdp中的DISABLE_ARCHIVE_LOGGING参数测试

在oracle 12c版本中引入了impdp中的TRANSFORM中的DISABLE_ARCHIVE_LOGGING值，可以实现在导入的时候使用nologging处理从而减少日志量也增加速度,但是在force logging情况下该参数无效

从上述测试在不管是非归档还是归档情况下使用DISABLE_ARCHIVE_LOGGING都会减小导入时间，减少归档量，但是需要注意如果数据库是force logging情况下，DISABLE_ARCHIVE_LOGGING参数会无效。

12c官方不支持裸设备,功能上依旧支持

根据官方描述:Announcement of DeSupport of using RAW devices in Oracle Database Version 12.1 (Doc ID 578455.1),从12.1开始oracle 彻底放弃了数据文件对raw的支持,但是我测试结果证明依旧可以使用（本测试只是证明功能上可以使用,不能说官方支持,稳定性和遭遇bug情况未知）,在条件允许情况下,不建议使用该方式.

从这里这里测试结果看,对于linux的block/raw/lvm设备依旧均可以在功能上做数据文件使用(稳定性和是否有其他bug未知).但没有出现mos中描述的直接报错,在条件允许的情况下,尽可能不要使用直接使用裸设备方式.
在12.2的administrator文档中出现明显描述：

Direct use of raw or block devices is not supported. You can only use raw or block devices under Oracle ASM.

crfclust.bdb文件过大处理

grid所在目录空间满

[root@wldb01 ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sdw2              40G   22G   17G  58% /

/dev/sdw1              50G   46G  1.5G  97% /u01

使用find命令找出来大文件

[root@wldb01 grid]# find ./ type f -size +1024M
./crf/db/wldb01/crfclust.bdb

由于文件crfclust.bdb是Cluster Health Monitor (CHM) file,他的默认大小是1G,但是有在一些平台和版本中由于bug原因导致过大.

asm 加磁盘导致磁盘组损坏恢复

接到客户恢复case请求，希望我们接入恢复数据。大概过程是这样的，16年9月份由于硬件问题，导致normal磁盘组(只有2个磁盘)中的一个磁盘丢失，然后在17年3月6日，运维方尝试增加该磁盘进入磁盘组，结果通过force命令加入成功之后，磁盘组dismount，然后再也无法mount成功。
磁盘组创建信息

这里可以看出来datadg是一个normal的au为4M的一个磁盘组

从这里我们可以看出来，前几次加asm disk 由于各种原因都失败了，最后一次通过加force关键字，使得被自动drop的disk重新强制加到datadg里面.可悲的是在加入成功之后,开始做rebalance的时候，发现disk 0出现坏块,从而引起ORA-15196的错误，使得rebalance无法进行下去,进而整个asm 磁盘组datadg自动dismount.后面再次尝试mount datadg的时候，直接提示元数据库不一致，因为disk 0 的磁盘头已经异常.

通过kfed分析disk 0信息
这里是通过dd命令备份的磁盘头到win进行分析的,以前正常的disk 0的磁盘头损坏(全0)

对于这个故障已经比较清楚，恢复思路也基本上确定：依次递进
方案1：通过kfed修改文件头，然后尝试mount磁盘头手工修复ASM DISK HEADER 异常
方案2：直接通过amdu,dul之类的工具拷贝出来数据文件找回ASM中数据文件
方案3：通过底层au重组出来数据文件asm disk header 彻底损坏恢复
在我们的实际恢复中运气比较好，通过方案1就完成了恢复工作，通过kfed修复磁盘头之后，然后报错如下

这里比较比较幸运，datadg已经mount成功了，但是由于rab依旧读取到disk header异常信息(没有完全修复成功,而且在日志中不光这个block异常，还有其他block异常，因此不考虑进一步修复),因此直接通过屏蔽asm的acd和cod实现该磁盘组mount,而且不会dismount。

asm的问题解决后，然后登录数据库，发现运气比较好，两个数据库正常open成功，而且alert日志无任何报错，直接通过rman备份出来数据，重建asm磁盘组，还原数据，恢复完成，而且实现数据0丢失。

mos上关于ora-600 3005描述

VERSIONS:
versions 10.2 and later
DESCRIPTION:
Raised during pass one of the two pass recovery processing, which
reads and merges open redo threads into a hash table of blocks
that need recovery.
During examination of the the change vectors of online redologs, this
error is raised if no online redo log could be opened to cover the start RBA.
ARGUMENTS:
Arg [a] Thread
Arg [b] Redo Log File Sequence
Arg {c} Redo Log File Block Number
Arg [d] SCN Wrap
Arg [e] SCN Base

根据官方描述，出现该错误的原因是由于在数据库启动的过程中，通过控制文件读取的redo信息不匹配，从而出现该问题，通过重建控制文件可以绕过去该问题
