刚开始出现了些问题，搞得我既郁闷又着急。都不知道我在记什么了，大家将就着看吧!
一个10G数据库的真实迁移过程(也可以说是一个数据库系统崩溃下的恢复过程)，要求停机的时间最短
前提:拥有完整的数据库备份和归档日志，迁移的主机所有的目录结构和原主机一样。
Oracle版本: 10.1.0.3.0
操作系统: linux2.6.11
备份程序:rman，没用恢复目录
把所有rman的备份(包括控制文件的自动备份)拷贝到新的服务器上，路径要和原来的一模一样。
迁移过程如下:
1、把参数文件，tns等文件拷贝到新服务器上，原数据库停机，开始把数据库迁移到新的服务器上。
$set oracle_sid=service
SQL conn / as sysdba
Connected.
SQLstartup nomount;
2、--恢复控制文件
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.
--这个过程我到现在还解，应该是只要控制文件自动备份，通过restore controlfile from autobackup就能恢复过来，但我在现场怎么实现不了。没办法，只要用dbms_backup_restore包了。
3、--把控制文件复制成三个文件
$ cp control01.ctl control02.ctl
$ cp control01.ctl control03.ctl
SQLalter database mount --数据库启动到mount状态准备进行数据文件的恢复
4、--启动rman

5、--查看归档日志
RMAN list backup archivelog all;
6、进行数据库的恢复
