朋友用到的一次不完全恢复案例与大家分享

前2天因为一次错误的truncate 操作，删除了hz用户下的几个表，费了1天多时间才恢复出来，在这里记录下恢复过程和这个深刻的教训。
使用坏境： oracle11.2+rhce5.5 RAC,归档模式,数据库有1TB容量。
在配置流环境时，因为一个误操作，删除了hz用户下的几个表。在这个数据库上还部署了其它几个用户，停机恢复数据显然是不可能的，分析情况后可以使用下面两种方式来恢复数据。
1、把当前库的备份文件和归档日志传到测试机上进行时间点不完全恢复，然后exp导出需要误删除的数据。
2、使用duplicate表空间的方式生成辅助数据库，在新库中导出需要的数据。
参考：http://space.itpub.net/7199859/viewspace-79054
这次的数据恢复操作我我使用第一种方式，以下是操作步骤：
1、拷贝数据文件和2节点的归档日志文件。由于故障库的备份是nfs挂载到备份机上的，省去了拷贝数据文件的时间，只需要把2节点下的archive日志文件拷贝到测试库上就行。
2、创建新库的pfile参数文件，拷贝故障库的spfile文件，修改参数并删除有关rac的不需要参数信息。
3、创建新库的密码文件.
orapwd file=/u02/app/oracle/product/11.2.0/db1/dbs/orapwklir passord=oracle entries=10 force=y
4、创建新库的dump目录。
5、启动新库到nomount下。

SQL> startup nomount pfile='/u02/pfile_klir.ora'
6、从备份集中恢复控制文件,并启动到mount状态下。
RMAN> restore controlfile from /orabk/ctl_c-949039848-20101116-00.ctl;
RMAN> alter database mount;
7、恢复表空间。因为只是一个表空间下的一些表被删除了，朋友建议我只恢复有问题的表空间就可以了，当然system，sysaux,undo这些基本的表空间是要恢复的。

<1>、有些日志文件在故障库的日志目录里是没有的，需要从备份中还原，不同节点的日志文件恢复时要写上thread=*命令，例如:

<4>、对于这种只是丢失部分表的情况，就可以只还原需要的表空间来打开数据库，可以节省大量的恢复时间。
使用坏境： oracle11.2+rhce5.5 RAC,归档模式,数据库有1TB容量。
在配置流环境时，因为一个误操作，删除了hz用户下的几个表。在这个数据库上还部署了其它几个用户，停机恢复数据显然是不可能的，分析情况后可以使用下面两种方式来恢复数据。
1、把当前库的备份文件和归档日志传到测试机上进行时间点不完全恢复，然后exp导出需要误删除的数据。
2、使用duplicate表空间的方式生成辅助数据库，在新库中导出需要的数据。
参考：http://space.itpub.net/7199859/viewspace-79054
这次的数据恢复操作我我使用第一种方式，以下是操作步骤：

2、创建新库的pfile参数文件，拷贝故障库的spfile文件，修改参数并删除有关rac的不需要参数信息。
3、创建新库的密码文件.
orapwd file=/u02/app/oracle/product/11.2.0/db1/dbs/orapwklir passord=oracle entries=10 force=y
4、创建新库的dump目录。
5、启动新库到nomount下。

10、打开数据库。
SQL> alter database open resetlogs;
经过几分钟的等待后，数据成功打开，登录数据库查询需要的文件都已经恢复出来了。谢天谢地！
这次数据恢复操作，用了近1天的时间，当时发生问题时我都快搞懵了，幸好在朋友的帮助下顺利完数据恢复，在这里要非常感谢他们！顺便记录下恢复期间遇到的几个问题。
<1>、有些日志文件在故障库的日志目录里是没有的，需要从备份中还原，不同节点的日志文件恢复时要写上thread=*命令，例如:
RMAN> restore archivelog from logseq 6914 until logseq 6915thread=2;

<2>、故障库恢复出日志文件后，因为在asm磁盘组里，要进入asmcmd里拷贝出日志文件。
ASMCMD> cp +ARCHIVE/klir/archivelog/2010_11_17/thread_1_seq_5705.369.735274973 /orabk/aaa/
<3>、恢复命令要写对，刚开始写的几种命令都不正确。
SQL> recover database until time '2010-11-16 16:25:00'
ORA-00283: recovery session canceled due to errorsITPUB个人空间7]&@M4Ly5K/@Q_

<4>、对于这种只是丢失部分表的情况，就可以只还原需要的表空间来打开数据库，可以节省大量的恢复时间。
