Oracle RMAN 在一台新机器上恢复另台机器的全备份

在一台新机器上恢复另台机器的全备份

1 要记住原机器的各种目录结构和DBID

2 在新机器上创建对应的目录结构 注意用户权限
/u01/oracle/admin/dbname/pfile bdump udump dpdump cdump
/oradata/dbname/rman_backup flash_recover_sea archivelog

3 把备份集文件放到新机器原来的备份目录中

3 Rman 连接到默认处

]$ export ORACLE_SID=surgesms
]$ ./rman target /
connected to target database (not started)

3 startup nomount 启动默认spfile
RMAN> startup nomount;

startup failed: ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/u01/oracle/product/10.2.0/dbs/initsurgesms.ora'

starting Oracle instance without parameter file for retrival of spfile
Oracle instance started

4 还原spfile 文件和控制文件
RMAN> set dbid 4223770157;
RMAN> restore spfile from '/oradata/{DB_NAME}/rman_backup/full.bak';
RMAN> restore controlfile from '/oradata/{DB_NAME}/rman_backup/full.bak';

5退出RMAN 再重进RMAN
RMAN> shutdown
RMAN> EXIT
bin]$ ./rman target /
RMAN> startup mount

6 察看是否使用了控制文件
RMAN> show all;
using target database control file instead of recovery catalog
