手工完全恢复（将数据文件恢复到新的位置）
实验环境：red hat 5.8
oracle环境：11.2.0.3
只坏一个文件
实验前先备份
使用脚本，冷备份和热备份
冷备份参考：http://blog.csdn.net/rlhua/article/details/11850445
热备份参考：http://blog.csdn.net/rlhua/article/details/11850629
1、首先建立一张测试用的表。
sys@TEST0910> conn scott/tiger
Connected.
scott@TEST0910> create table test4 as select * from emp;
Table created.
2、插入三次数据，分别为提交归档，提交不归档，不提交不归档
sys@TEST0910> insert into scott.test4 select * from scott.emp;
14 rows created.
sys@TEST0910> commit;
Commit complete.
sys@TEST0910> alter system archive log current;
System altered.
sys@TEST0910> select count(*) from scott.test4;
COUNT(*)
----------
28
sys@TEST0910> insert into scott.test4 select * from scott.emp;
14 rows created.
sys@TEST0910> commit;
Commit complete.
sys@TEST0910> select count(*) from scott.test4;
COUNT(*)
----------
42
sys@TEST0910> insert into scott.test4 select * from scott.emp;
14 rows created.
sys@TEST0910> select count(*) from scott.test4;
COUNT(*)
----------
56
3、模拟断电。
sys@TEST0910> shutdown abort;
ORACLE instance shut down.
4、删除数据文件
[oracle@rtest ~]$ rm /u01/app/oracle/oradata/test0910/users01.dbf
5、起库，报错，查询哪个文件损坏。
sys@TEST0910> startup
ORACLE instance started.
Total System Global Area 2505338880 bytes
Fixed Size 2230952 bytes
Variable Size 587203928 bytes
Database Buffers 1895825408 bytes
Redo Buffers 20078592 bytes
Database mounted.
ORA-01157: cannot identify/lock data file 4 - see DBWR trace file
ORA-01110: data file 4: '/u01/app/oracle/oradata/test0910/users01.dbf'
sys@TEST0910> select file#,error from v$recover_file;
FILE# ERROR
---------- -----------------------------------------------------------------
4 FILE NOT FOUND
6、使用高可用模式，先开库，后恢复
先让datafile offline
sys@TEST0910> alter database datafile 4 offline;
Database altered.
sys@TEST0910> alter database open;
Database altered.
7、转储到新的位置
[oracle@rtest disk1]$ cp /u01/app/oracle/bak/hot_bak/users01.dbf /u01/app/oracle/oradata/test0910/disk1/users01.dbf
[oracle@rtest disk1]$ ls
users01.dbf
8、使用rename改变位置
sys@TEST0910>
alter database rename file '/u01/app/oracle/oradata/test0910/users01.dbf' to '/u01/app/oracle/oradata/test0910/disk1/users01.dbf';
Database altered.
9、恢复数据文件，容乃公数据文件online
sys@TEST0910> recover datafile 4;
