7、 检查数据库的数据（完全恢复） SQL> select * from test; A
--------------------------------------- 1 2 说明：
1、只要有备份与归档存在，RMAN也可以实现数据库的完全恢复（不丢失数据）; 2、同OS备份数据库恢复，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、目标数据库在mount下进行，如果恢复成功，再打开数据库;
4、RMAN的备份与恢复命令相对比较简单并可靠，建议有条件的话，都采用RMAN进行数据库的备份。
4.4 不完全恢复案例
4.4.1 OS备份下的基于时间的恢复
不完全恢复可以分为基于时间的恢复，基于改变的恢复与基于撤消的恢复，这里已基于时间的恢复为例子来说明不完全恢复过程。
基于时间的恢复可以不完全恢复到现在时间之前的某一个时间，对于某些误操作，如删除了一个数据表，可以在备用恢复环境上恢复到表的删除时间之前，然后把该表导出到正式环境，避免一个人为的错误。
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，这里最好备份所有的数据文件，包括临时数据文件:
SQL> @hotbak.sql 或在DOS下 svrmgrl @hotbak.sql 或冷备份也可以
3、 删除测试表，假定删除前的时间为T1，在删除之前，便于测试，继续插入数据并应用到归 档。
SQL> insert into test values(2); 1 row inserted SQL> commit; Commit complete
SQL> select * from test; A
--------------------------------------- 1 2 SQL> alter system switch logfile; Statement processed.
SQL> alter system switch logfile; Statement processed.
SQL> select to_char(sysdate,'yyyy-mm-dd hh24:mi:ss') from dual; TO_CHAR(SYSDATE,'YY ------------------- 2003-05-21 14:43:01
