1、 环境：操作系统aix5.2，数据库Oracle9.2
2、 模拟环境：
1）首先使用rman作整个数据库备份
2）时间：
# date
Tue Aug 23 17:35:19 BEIDT 2005
3）操作：
sql>truncate table scott.emp
3、 恢复数据库到2005年8月23日17点35分19秒
4、 数据库到mount状态
5、 设置变量
$set nls_date_format=yyyy-mm-dd:hh24:mi:ss
6、 连接到rman
$rman target / catalog rman/rman@omsora9
RMAN> run {
2> set until time="to_date('2005-08-23:17:35:19','yyyy-mm-dd:hh24:mi:ss')";
3> restore database;
4> recover database;
5> }
executing command: SET until clause
