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
www.imissha.com 谜尚bb霜 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*Plus: Release 8.1.6.0.0 - Production on Tue May 6 13:46:32 2003 (c) Copyright 1999 Oracle Corporation. All rights reserved. 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。
Recovery Manager: Release 8.1.6.0.0 - Production RMAN> # script:bakup.rcv 2> # creater:chenjiping 3> # date:5.8.2003

10> #start backup database 11> run{
12> allocate channel c1 type disk;
13> backup full tag 'dbfull' format 'd:backupfull%u_%s_%p' database 14> include current controlfile;
15> sql 'alter system archive log current'; 16> release channel c1; 17> }

SQL> alter system switch logfile; System altered.
SQL> alter system switch logfile; System altered.
4、关闭数据库，模拟丢失数据文件 SQL> shutdown immediate; Database closed.
