ORACLE中采用rman备份异机恢复数据库详细过程
场景：
有一个生产库的用户下面所有的表都不见了，怀疑人为被删除了，现在需要用备份去恢复下，找出原来的表，线上是oracle dataguard环境，有全库备份文件，准备去测试库恢复一下。
1，从生产库上copy好全备份文件
恢复数据库需要准备的文件：rman完整备份（包括数据文件、日志文件、控制文件、参数文件），记录源数据库的DBID
安装的测试数据库ORACLE数据库软件并创建跟源数据库同名和数据库SID并修改数据库DBID跟源数据库DBID一样，创建跟源数据库服务器相同的数据文件目录、日志文件目录、控制文件目录。
查看环境
1.1，查看参数文件信息

2.1 设置DBID：
注意：在rman下即使没有参数文件，默认也会启动一个DUMMY实例，以便能够恢复参数文件。

3，recover问题分析
去原来备份库上找到缺失的 29167到29186的dbf文件，copy到测试库（需要恢复的db服务器）的归档日志目录下，如果不知道现在归档日志，可以直接用sysdba登录查看当前归档日志目录，如下所示：
3.1，查看原来备份库上的归档信息

3.2，copy备份库上面的 29167到29186的dbf归档日志文件到测试库的归档日志目录下面

3.3,查看到原来的归档目录和测试库一样，所以尝试下继续执行recover命令，然后继续在测试库的rman界面，进行recover操作：

3.3，看到有报错，还是缺失归档日志包，去现在测试库/oracle/app/oracle/flash_recovery_area/archivelog/下面看了没有新的29187归档日志，所以从原来备份库上copy过来的归档日志都应该执行完了，直接试试打开open。
RMAN> alter database open resetlogs;
database opened
RMAN>
OK，到这里rman恢复已经完全成功结束。
4，登录连接验证，验证连接报错：
[oracle@xuexi4 admin]$ sqlplus "sys/sys@SC_PD";
SQL*Plus: Release 11.2.0.1.0 Production on Mon Feb 2 19:23:32 2015
Copyright (c) 1982, 2009, Oracle. All rights reserved.
ERROR:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor
去检查tnsnames.ora
SC_XDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.121.217)(PORT = 1521))
)
(CONNECT_DATA =http://www.mamicode.com/
(SERVICE_NAME = stuorcl)
)
)
登录去检查当前库的db_unique_name信息
SQL> show parameter name;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_file_name_convert string /home/oradata/stuorcl, /home/
oradata/pwerdes
db_name string stuorcl
db_unique_name string stuunq
global_names boolean FALSE
instance_name string stuorcl
lock_name_space string
log_file_name_convert string /home/oradata/stuorcl, /home/
oradata/stuorcl
service_names string stuunq
SQL>
发现db_unique_name是另外一个，所以将tnsnames.ora里面的service_name从stuorcl换成了stuunq，就可以连接成功了。
5，找到原来的用户下的表，导出来恢复到线上。
总结步骤：
1，scp全备文件到测试库，在备份库上查询好参数文件控制文件归档路径等信息
2，关闭测试库，启动到nomount状态，恢复参数文件控制文件
3，启动到mount状态，restore、recover操作
4，打开数据库alter database open resetlogs;
