小編給大家分享一下Linux環境下oracle數據庫Rman備份如何實現異機恢復,相信大部分人都還不怎么了解,因此分享這篇文章給大家參考一下,希望大家閱讀完這篇文章后大有收獲,下面讓我們一起去了解一下吧!
備份的數據庫和要恢復的數據庫OS和數據庫的版本均一致,恢復的目錄也均一致!
備份數據庫:
RMAN> backup format ‘/home/oracle/scripts/full_prod.%U’ database plus archivelog;
備份控制文件:
RMAN> backup current CONTROLFILE format '/home/oracle/scripts/control.%U';
確認所有文件夾路徑,備庫最好要創建和源庫一樣的路徑,否則需要指定路徑。
SYS@PROD> select name from v$datafile;
SYS@PROD> select member from v$logfile;
SYS@PROD> select name from v$controlfile;
傳輸spfile到要恢復的服務器
[oracle@wangxx1 dbs]$ scp spfilePROD.ora 172.16.12.117:/u01/app/oracle/product/11.2.0/dbhome_1/dbs
SYS@PROD> create pfile from spfile;
根據pfile文件位置創建相應的目錄
[oracle@wangxx2 ~]$ mkdir -p /u01/app/oracle/oradata/PROD/
[oracle@wangxx2 dbs]$ mkdir -p /u01/app/oracle/admin/PROD/adump
傳輸備份文件到相同位置
[oracle@wangxx1 scripts]$ scp full 172.16.12.117:/home/oracle/scripts
[oracle@wangxx1 scripts]$ scp control 172.16.12.117:/home/oracle/scripts
從指定備份集恢復控制文件
[oracle@wangxx2 scripts]$ rman target /

RMAN> set DBID=358601116
RMAN> restore CONTROLFILE from '/home/oracle/scripts/control.07so5c0l_1_1';

using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=10 device type=DISK
channel ORA_DISK_1: restoring control file

RMAN> restore database;
RMAN> recover database;
Starting recover at 08-JAN-18

using channel ORA_DISK_2
starting media recovery
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
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
報錯屬于正常,因為聯機日志沒有拷貝過來!
RMAN> alter database open resetlogs;
database opened
SYS@PROD> select status from v$instance;
OPEN
