如何克隆的目标主机含有Oracle EBS的运行实例，那么可以跳过操作系统补丁和一些必要软件的检查，否则需要查询Oracle EBS安装前必要的一些软件是否安装全或者操作系统参数是否配置。（如果已经有Oracle EBS正在运行，证明这些软件都已经安装了，不用检查。具体请查看Oracle EBS安装文档。）
1. If your target server holds at least one Oracle Apps R12.1.3 instance,you can skip for any OS patch or software requirement section. As the server is running a Oracle Apps instance,we can assume the server has all the
mandatory OS patch and required software. Else look into the Metalink for platform specific requirements.
2.Apply Latest AD patch
Check whether AD patch version is atleast R12.AD.B.3. You can check that using following query.
SELECTpatch_levelFROMfnd_product_installationsWHEREpatch_levelLIKE'R12.AD%'
If it is below that level apply patch 9239089.
检查现在的EBS系统是否安装AD patch补丁 R12.AD.B.3（一般都回安装的）可以通过上面的sql语句查看是否安装该补丁。
3.Apply the latest AutoConfig template patch
Update the Oracle Applications file system with the AutoConfig files by applying the latest AutoConfig Template patch (Patch 9386653 for 12.0.X customers and Patch 8919489 for 12.1.X customers) to all application tier nodes in the Applications instance. You can check whether this patch is already there or not in your system by the following sql.
SELECT*FROMad_applied_patchesWHEREpatch_name ='8919489'

4.Apply the latest Rapid Clone patches
For Release 12.1 apply following patches.
