通过查询v$recover_file可以看到 SQL> select * from v$recover_file;
FILE# ONLINE ERROR CHANGE# TIME ---------- ------- ------------------ ---------- ----------- 1 ONLINE FILE NOT FOUND 0 2 ONLINE FILE NOT FOUND 0 5 ONLINE FILE NOT FOUND 0 6 ONLINE FILE NOT FOUND 0 有四个数据文件需要恢复
6、 拷贝备份回到原地点(restore)，开始恢复数据库(recover) restore过程:
C:\\>copy D:\\DATABAK\\SYSTEM01.DBF D:\\Oracle\\ORADATA\\TEST\\ C:\\>copy D:\\DATABAK\\TEST\\INDX01.DBF D:\\Oracle\\ORADATA\\TEST\\ C:\\>copy D:\\DATABAK\\TEST\\TOOLS01.DBF D:\\Oracle\\ORADATA\\TEST\\ C:\\>copy D:\\DATABAK\\TEST\\RBS01.DBF.DBF D:\\Oracle\\ORADATA\\TEST\\
Recover过程:
SQL> recover database;

7、 打开数据库，检查数据库的数据（完全恢复） SQL> alter database open; Database altered. SQL> select * from test; A
--------------------------------------- 1 2
说明：
1、只要有备份与归档存在，就可以实现数据库的完全恢复（不丢失数据）; 2、适合于丢失大量数据文件，或包含系统数据文件在内的数据库的恢复; 3、恢复过程在mount下进行，如果恢复成功，再打开数据库，down机时间可能比较长一些。
4.3.2 RMAN备份方案
RMAN备份归档模式下损坏（丢失）多个数据文件，进行整个数据库的恢复 1、连接数据库，创建测试表并插入记录
SQL> connect internal/password as sysdba; Connected.
SQL> create table test(a int); Table created
SQL> insert into test values(1); 1 row inserted SQL> commit; Commit complete
2、备份数据库
DOS下 C:>\\ rman cmdfile=bakup.rcv msglog=backup.log;
以下是backup.log内容。
