常规的rapid clone都是需要停掉EBS才能去clone的.但是很多时候客户是不允许的.所以我下面就简单的介绍一下用rman在线cloneEBS的步骤,仅供参考：
1.Run preclone in ap &db
2.Copy APP Tier and DB Oracle home to target host
3.Backup database using rman and copy to target host
4.Modify init parameter and listener.ora
5.configure env variable
6.restore database and modify db_name
7.create db xml and run autconfig in db
8.run cfgclone in app tier.
9.modify xml file and start EBS
请详细看上面的步骤,理解后再进行操作,如有问题在讨论.
