如何使用 RMAN 异机恢复部分表空间

在oracle 数据库的日常维护和使用期间难免会遇到误删数据(drop,delete, truncate)当我们使用常规手段(flashback query ,flashback drop)也无法恢复数据时,我们可以使用最近的逻辑备份,在异机使用dmp 来恢复相应的表,但是如果没有这些逻辑备份,但是有一个最近的rman 全备,那么我们就可以利用这个备份来恢复被误删的表空间,从而实现数据的恢复,这里我以NBU 的备份环境为例简单描述下如何来回复部分 表空间: -------在nomount 状态

1.全库备份,scp到异机目录下  查询源库的DBID:   SQL> select dbid,name from v$database; DBID NAME ---------- ---------  439840715 YIJI SQL>    异机建立dump目录.oradata下建立SID名对应目录  2.恢复spfile,启动到nomount:       export ORACLE_SID=yiji    rman target /    set dbid=439840715
