oracle linux6操作系統oracle11.2.0.4數據庫從一臺主機A（ora11g）到另一臺主機B（ora02）的遷移過程
A生成pfile文件並關閉數據庫
[oracle@ora11g ~]$ sqlplus /nolog

[oracle@ora11g ~]$
A將密碼文件，參數文件複製到B
[oracle@ora11g dbs]$ pwd
/u01/app/oracle/product/11.2.0/dbhome_1/dbs
[oracle@ora11g dbs]$ scp orapwORCL 192.168.56.18:/u01/app/oracle/product/11.2.0/dbhome_1/dbs

B根據參數文件創建相應目錄
[oracle@ora02 Desktop]$ mkdir -p /u01/app/oracle/admin/ORCL/adump
[oracle@ora02 Desktop]$ mkdir -p /u01/app/oracle/oradata/ORCL/
[oracle@ora02 Desktop]$ mkdir -p /u01/app/oracle/fast_recovery_area/ORCL/
A將控制文件，日誌文件，數據文件複製到B
[oracle@ora11g ORCL]$ scp control01.ctl 192.168.56.18:/u01/app/oracle/fast_recovery_area/ORCL/control02.ctl

B新建目錄並將數據文件複製過去
[root@ora02 ~]# mkdir -p /u02/app/oracle/oradata/ORCL
[root@ora02 ~]# chown -R oracle:oinstall /u02/
[oracle@ora02 Desktop]$ cd /u01/app/oracle/oradata/ORCL/
[oracle@ora02 ORCL]$ ls
control01.ctl redo02.log sysaux01.dbf temp01.dbf users01.dbf
redo01.log redo03.log system01.dbf undotbs01.dbf
[oracle@ora02 ORCL]$ mv *.dbf /u02/app/oracle/oradata/ORCL/
B將數據庫啓動到mount狀態
[oracle@ora02 Desktop]$ sqlplus /nolog
