A.M.D.U数据恢复
客户环境：
操作系统：RedHat Enterprise AS Linux 4.6 x64
数据库DB：Oracle Enterprise Database 10g(10.2.0.4) no psu
集群系统：Oracle Real Application Cluster 10g(10.2.0.4) no psu
问题背景：
在一个寂静的夜晚被一阵急促的电话铃声吵醒，打来电话的是我的老朋友J，他告知我说数据库起不来了，业务全部中断，存储狂扇，频繁的告警亮灯，寻求我的紧急帮助。我首先安慰老朋友J，说这个可能是存储有问题，比较棘手，还是有修复的可能。J听到我这么一说长舒了一口气，缓缓的吐了几个字说：“吴哥，你得帮帮我！”我说没问题，随即梦醒打了个飞的直奔故障现场。了解到了客户环境：比想象中的更为复杂，上线后就没有任何备份，是一个部署在RHEL4.6环境下的10g(10.2.0.4)的RAC，用的是8盘位DFT低端SAS存储。
问题分析：
在了解到问题环境之后需要对问题进行进一步的分析和解决，思考了半个小时，CRS服务无法启动，没有数据库备份无法恢复；10gRAC ASM无法mount，内部视图无法查询，磁盘组无法正常加载，给数据恢复带来诸多不便......，看来常规方法是不行了，只能考虑一些非常规的数据恢复方法：DUL? AUL? ODU? 这几个工具一直在大脑中回荡，后来冷静思考，咨询了行业里面的牛人，告诉我说通过11g下的AMDU可以在磁盘组加载之前将ASM元数据抽出来，用于诊断及起库open，之后再重做RAC恢复数据即可。且该工具可以向后兼容，引入到10g中。
说完就干～！
处理过程：
1.1.基础环境准备
在Oracle官网下载最新的AMDU工具，在任意节点挂载外置移动硬盘，上传到挂载外置移动硬盘的节点上，进去后赋予oracle:oinstall权限并用oracle用户解压，配置参数文件amdu_par，包含如下内容：
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:`pwd`
export PATH=$PATH:`pwd`
1.2. 初始化amdu工具
用oracle用户执行如下命令，将自动生成一个以时间命名的目录，其下的报告
文件记录了磁盘组的相关信息。
./amdu amdu_2019_03_30_12_26_32
该报告的主要信息如下：

1.3.抽取控制文件
由于磁盘组不能Mount，控制文件也无法访问，因此需要首先分析数据库的文件分布情况，进而通过文件的ASM 存储序号来进行文件抽取，通过告警日志，可以找到数据库的控制文件信息。如下所示，控制文件的ASM 文件号是270。
grep control_file $ORACLE_BASE/admin/$ORACLE_SID/bdump/alert_$ORACLE_SID.log control_files = "+ORADATA_DG1/ORADB/CONTROLFILE/Current.260.739555035" .......... [oracle@rac1 amdu_2019_03_30_12_26_32]$ amdu -diskstring '/dev/oracleasm/disks/VOL*' -extract ORADATA_DG1.260 amdu_2019_03_30_12_29_43/
1.4. 通过控制文件获取RedoLog 和DataFile
取得控制文件之后，可以通过控制文件内容获得数据库的数据文件及日志文件分布情况。以下是从控制文件中获得的信息输出。
[root@rac1 ~]# strings ORADATA_DG1_260.f |grep -v archivelog |grep -v oracle/ |grep ORAD| sort +ORADATA_DG1/oradb/idx_jsnet.dbf +ORADATA_DG1/oradb/idx_jsnet.dbf +ORADATA_DG1/oradb/idx_jsnet.ora +ORADATA_DG1/oradb/idx_jsnet.ora +ORADATA_DG1/oradb/redo01.log +ORADATA_DG1/oradb/redo01.log +ORADATA_DG1/oradb/redo02.log +ORADATA_DG1/oradb/redo02.log +ORADATA_DG1/oradb/redo03.log +ORADATA_DG1/oradb/redo03.log +ORADATA_DG1/oradb/redo04.log +ORADATA_DG1/oradb/redo04.log +ORADATA_DG1/oradb/sysaux01.dbf +ORADATA_DG1/oradb/sysaux01.dbf +ORADATA_DG1/oradb/system01.dbf +ORADATA_DG1/oradb/system01.dbf +ORADATA_DG1/oradb/tbs_jsnet.dbf +ORADATA_DG1/oradb/tbs_jsnet.dbf +ORADATA_DG1/oradb/tbs_jsnet.dbf +ORADATA_DG1/oradb/tbs_jsnet.dbf +ORADATA_DG1/oradb/temp01.dbf +ORADATA_DG1/oradb/temp01.dbf +ORADATA_DG1/oradb/undotbs01.dbf +ORADATA_DG1/oradb/undotbs01.dbf +ORADATA_DG1/oradb/undotbs02.dbf +ORADATA_DG1/oradb/undotbs02.dbf +ORADATA_DG1/oradb/users01.dbf +ORADATA_DG1/oradb/users01.dbf
1.5. 恢复文件
根据控制文件中的文件分布信息，可以通过amdu工具将所有文件提取出来，根据以数据文件和日志文件信息，创建如下脚本以抽取对应的日志文件和数据文件。
先恢复RedoLog File:
[oracle@rac1 amdu_2019_03_30_12_26_32]$ amdu -diskstring '/dev/oracleasm/disks/VOL*' -extract ORADATA_DG1.263 amdu_2019_03_30_12_32_38/ [oracle@rac1 amdu_2019_03_30_12_26_32]$ amdu -diskstring '/dev/oracleasm/disks/VOL*' -extract ORADATA_DG1.264 amdu_2019_03_30_12_33_12/ [oracle@rac1 amdu_2019_03_30_12_26_32]$ amdu -diskstring '/dev/oracleasm/disks/VOL*' -extract ORADATA_DG1.267 amdu_2019_03_30_12_34_11/ [oracle@rac1 amdu_2019_03_30_12_26_32]$ amdu -diskstring '/dev/oracleasm/disks/VOL*' -extract ORADATA_DG1.268 amdu_2019_03_30_12_34_22/
再恢复数据文件：
IDX_JSNET.ora: [oracle@rac1 amdu_2019_03_30_12_26_32]$ amdu -diskstring '/dev/oracleasm/disks/VOL*' -extract ORADATA_DG1.276 amdu_2019_03_30_12_38_42/ IDX_JSNET: [oracle@rac1 amdu_2019_03_30_12_26_32]$ amdu -diskstring '/dev/oracleasm/disks/VOL*' -extract ORADATA_DG1.298 TBS_JSNET: [oracle@rac1 amdu_2019_03_30_12_26_32]$ amdu -diskstring '/dev/oracleasm/disks/VOL*' -extract ORADATA_DG1.277 SYSAUX: [oracle@rac1 amdu_2019_03_30_12_26_32]$ amdu -diskstring '/dev/oracleasm/disks/VOL*' -extract ORADATA_DG1.257 SYSTEM: [oracle@rac1 amdu_2019_03_30_12_26_32]$ amdu -diskstring '/dev/oracleasm/disks/VOL*' -extract ORADATA_DG1.256 TEMP: [oracle@rac1 amdu_2019_03_30_12_26_32]$ amdu -diskstring '/dev/oracleasm/disks/VOL*' -extract ORADATA_DG1.265 UNDOTBS1: [oracle@rac1 amdu_2019_03_30_12_26_32]$ amdu -diskstring '/dev/oracleasm/disks/VOL*' -extract ORADATA_DG1.258 UNDOTBS2: [oracle@rac1 amdu_2019_03_30_12_26_32]$ amdu -diskstring '/dev/oracleasm/disks/VOL*' -extract ORADATA_DG1.266 USER: [oracle@rac1 amdu_2019_03_30_12_26_32]$ amdu -diskstring '/dev/oracleasm/disks/VOL*' -extract ORADATA_DG1.259
1.6. 校验文件
到这里文件已经全部恢复出来了，途中未见报错，接下来需要用dbv对文件进行个校验，检查下是否有逻辑坏块：
[oracle@rac1 amdu_2019_03_30_12_26_32]$ dbv file=amdu_2019_03_30_12_ amdu_2019_03_30_12_29_43/ amdu_2019_03_30_12_33_12/ amdu_2019_03_30_12_38_42/ amdu_2019_03_30_12_43_30/ amdu_2019_03_30_12_29_56/ amdu_2019_03_30_12_34_11/ amdu_2019_03_30_12_40_08/ amdu_2019_03_30_12_44_47/ amdu_2019_03_30_12_30_07/ amdu_2019_03_30_12_34_22/ amdu_2019_03_30_12_40_45/ amdu_2019_03_30_12_32_38/ amdu_2019_03_30_12_37_22/ amdu_2019_03_30_12_42_13/ [oracle@rac1 amdu_2019_03_30_12_26_32]$ dbv file=amdu_2019_03_30_12_38_42/ORADATA_DG1_276.f DBVERIFY: Release 10.2.0.4.0 - Production on Sat Mar 30 14:00:33 2019 Copyright (c) 1982, 2007, Oracle.

1.7. 验证数据库版本及补丁信息
[oracle@rac1 amdu_2019_03_30_12_26_32]$ $ORACLE_HOME/OPatch/opatch lsinv Invoking OPatch 10.2.0.4.2 Oracle Interim Patch Installer version 10.2.0.4.2 Copyright (c) 2007, Oracle Corporation.

2、构建新的环境
2.1. 安装相同版本数据库
不要建库，只需安装数据库软件即可。
过程(略)
2.2. 创建数据库启动参数文件
编辑好参数文件，将数据库启动到nomount状态:
[oracle@rac1 dbs]$ cat initoradb.ora db_name=oradb db_files = 80 db_file_multiblock_read_count = 8 db_block_buffers = 100 shared_pool_size = 123232153 log_checkpoint_interval = 10000 processes = 50 parallel_max_servers = 5 log_buffer = 32768 max_dump_file_size = 10240 global_names = TRUE control_files = '/oracle/oradata/oradb/control01.ctl'
2.3. 将数据库启到nomount状态
[oracle@rac1 dbs]$ sqlplus / as sysdba SQL*Plus: Release 10.2.0.4.0 - Production on Sat Apr 6 12:47:26 2019 Copyright (c) 1982, 2007, Oracle. All Rights Reserved. Connected to an idle instance. SQL> startup nomount; ORACLE instance started.

2.4. mount数据库
SQL> alter database mount; Database altered. SQL> select instance_name,status from gv$instance; INSTANCE_NAME STATUS ---------------- ------------ oradb MOUNTED
接下来就可以修改控制文件里面对应的数据文件及RedoLog的路径，并open数据库了。
2.5 修改路径
修改控制文件中的数据文件和RedoLog对应路径信息。
RedoLog File RENAME FILE:
