说明:
target 是指出问题的库
aux 是还原出来的备份库
注意:
target必须是归档模式
步骤
0、为target做全库的rman备份
1、为aux建立init文件
2、为aux建立相应目录及文件夹
3、指定时间点,执行恢复操作
4、得到数据,清理现场
0、为target做全库的rman备份

1、为aux建立init文件,并且修改正确后要cp到 $ORACLE_HOME/dbs目录下,

[oracle@centora tspitr]$ cp initts.ora /u01/app/oracle/product/10.2.0/db_1/dbs/inittspitr.ora
2、为aux建立相应目录及文件夹
3、指定时间点,执行恢复操作

如果不想复制一些表空间,可以skip它们,脚本类似
run {
SET until time "TO_DATE('2006-01-09 17:26:00','YYYY-MM-DD HH24:MI:SS')";
DUPLICATE TARGET DATABASE TO AUX
SKIP TABLESPACE indx,tools;
}
但是system,undo表空间是不能skip的。
还可以指定redolog文件的大小,脚本类似
run {
