AMDU数据恢复的方法是什么
这篇文章主要介绍“AMDU数据恢复的方法是什么”,在日常操作中,相信很多人在AMDU数据恢复的方法是什么问题上存在疑惑,小编查阅了各式资料,整理出简单好用的操作方法,希望对大家解答”AMDU数据恢复的方法是什么”的疑惑有所帮助!接下来,请跟着小编一起来学习吧!
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

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

[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:

'/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_

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
