Linux环境下oracle数据库Rman备份如何实现异机恢复

小编给大家分享一下Linux环境下oracle数据库Rman备份如何实现异机恢复，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！

备份的数据库和要恢复的数据库OS和数据库的版本均一致，恢复的目录也均一致！
备份数据库：
RMAN> backup format ‘/home/oracle/scripts/full_prod.%U’ database plus archivelog;
备份控制文件：
RMAN> backup current CONTROLFILE format '/home/oracle/scripts/control.%U';
确认所有文件夹路径，备库最好要创建和源库一样的路径，否则需要指定路径。
SYS@PROD> select name from v$datafile;
SYS@PROD> select member from v$logfile;
SYS@PROD> select name from v$controlfile;
传输spfile到要恢复的服务器
[oracle@wangxx1 dbs]$ scp spfilePROD.ora 172.16.12.117:/u01/app/oracle/product/11.2.0/dbhome_1/dbs
SYS@PROD> create pfile from spfile;
根据pfile文件位置创建相应的目录
[oracle@wangxx2 ~]$ mkdir -p /u01/app/oracle/oradata/PROD/
[oracle@wangxx2 dbs]$ mkdir -p /u01/app/oracle/admin/PROD/adump
传输备份文件到相同位置
[oracle@wangxx1 scripts]$ scp full 172.16.12.117:/home/oracle/scripts
[oracle@wangxx1 scripts]$ scp control 172.16.12.117:/home/oracle/scripts
从指定备份集恢复控制文件
[oracle@wangxx2 scripts]$ rman target /

RMAN-03002: failure of recover command at 01/08/2018 11:23:34
RMAN-06053: unable to perform media recovery because of missing log
RMAN-06025: no backup of archived log for thread 1 with sequence 49 and starting SCN of 2002997 found to restore
报错属于正常，因为联机日志没有拷贝过来！
RMAN> alter database open resetlogs;
database opened
SYS@PROD> select status from v$instance;
