剛開始出現了些問題，搞得我既郁悶又著急。都不知道我在記什麼了，大家將就著看吧!
一個10G數據庫的真實遷移過程(也可以說是一個數據庫系統崩潰下的恢復過程)，要求停機的時間最短
前提:擁有完整的數據庫備份和歸檔日志，遷移的主機所有的目錄結構和原主機一樣。
Oracle版本: 10.1.0.3.0
操作系統: Linux2.6.11
備份程序:rman，沒用恢復目錄
把所有rman的備份(包括控制文件的自動備份)拷貝到新的服務器上，路徑要和原來的一模一樣。
遷移過程如下:
1、把參數文件，tns等文件拷貝到新服務器上，原數據庫停機，開始把數據庫遷移到新的服務器上。
$set Oracle_sid=service
SQL> conn / as sysdba
Connected.
SQL>startup nomount;
2、--恢復控制文件
SQL> declare
devtype varchar2(256);
done boolean;
begin
devtype :=dbms_backup_restore.deviceallocate(NULL);
dbms_backup_restore.restoresetdatafile;
dbms_backup_restore.restorecontrolfileto("/opt/data/SERVICE/control01.ctl"); dbms_backup_restore.restorebackuppIEce("/opt/backup/control_c-4194659530-20050805-01",DONE => done);
end;
/
PL/SQL procedure successfully completed.
--這個過程我到現在還解，應該是只要控制文件自動備份，通過restore controlfile from autobackup就能恢復過來，但我在現場怎麼實現不了。沒辦法，只要用dbms_backup_restore包了。
3、--把控制文件復制成三個文件
$ cp control01.ctl control02.ctl
$ cp control01.ctl control03.ctl
SQL>alter database mount --數據庫啟動到mount狀態准備進行數據文件的恢復
4、--啟動rman
