RMAN迁移数据库（RMAN异机恢复）
源库和目标库的数据库软件版本需要一致（已安装数据库软件），操作系统架构需一致。源库名为mydb，dbid号为
在源和目标服务器创建备份目录（源为172.16.100.100，目标为172.16.100.200）
[oracle@localhost u01]$ mkdir -p /u01/backup
在源库用RMAN进行全备数据库，记住dbid号。
[oracle@localhost backup]$ export ORACLE_SID=mydb
[oracle@localhost backup]$ rman target /

拷贝备份文件到目标库，并创建好数据库相关目录
[root@localhost u01]# scp backup/* oracle@172.16.100.200:/u01/backup
[oracle@localhost admin]$ mkdir -p /u01/app/oracle/admin/mydb/{adump,bdump,cdump,dpdump,udump,pfile}
[oracle@localhost oradata]$ mkdir –p /u01/app/oracle/oradata/mydb
[oracle@localhost flash_recovery_area]$ mkdir –p /u01/app/oracle/flash_recovery_area/mydb
目标库进行恢复
[oracle@localhost backup]$ export ORACLE_SID=mydb
