OS ： redhat 5.7 ?（因为手头上没有redhat 6对应的专用的补丁，只有redhat5专用的补丁包。所以以redhat5.7为os安装）
EBS版本： 12.2 （从edelivery上下载，下载完毕看一下readme，因为里面的东西不全，要再次下载）

安装介质
因为从edelivery.oracle.com上下载的安装介质。发现R12.2的大小居然比R12.1的大小还小。
最后在安装的时候，发现，没有以下内容：（随后在edelivery上下载这些）
Prerequisite:
-------------
1. StartCD 12.2.0.51 ?(Patch#22066363, RAPID INSTALL STARTCD 12.2.0.51) installs Oracle Fusion Middleware 11g PS7 (11.1.1.9.0) and Database 12.1.0.2.
As StartCD 12.2.0.51 requires Oracle Fusion Middleware 11g PS7 (11.1.1.9.0) and Database 12.1.0.2, create the buildStage area afresh using buildStage.sh (buildStage.cmd for Windows) script after downloading the Oracle E-Business Suite Release 12.2 Media Pack.
NOTE: The earlier buildStage area created with StartCD 12.2.0.50 or earlier cannot be re-purposed here as it contains Oracle Fusion Middleware 11g PS6 (11.1.1.7.0) or lower whereas StartCD 12.2.0.51 requires Oracle Fusion Middleware 11g PS7 (11.1.1.9.0) and Database 12.1.0.2. ?Stage area has to be created afresh after downloading the latest Oracle E-Business Suite Release 12.2 Media Pack. Refer to 'Oracle E-Business Suite Installation Guide: Using Rapid Install (Part No. E22950)' guide for more information about creating stage area and other prerequisites.
'Oracle E-Business Suite Release Notes, Release 12.2 (Doc ID 1320300.1)' must also be referenced for all other required prerequisites, known issues, etc.
第一次解压的时候，直接使用unzip解压，安装后发现包不全，建议使用start CD里面的脚本解压，有哪些没有的，会提示
提示的内容如下：
pecify the directory containing the zipped installation media:
/12.2.ins/zip/
File list:
/12.2.ins/zip/startCD/Disk1/rapidwiz/bin/stageData/zipFiles.dat
The following files are missing from /12.2.ins/zip/.

在edelivery.oracle.com上下载，解压后的文件如下：

接下来就是安装。因为db节点和ap节点安装在同一个机器上，机器8G内存，小了点，所以安装了大约5-6个小时（网上看，安装db的时候，因为默认是开了并行的，CPU不足的话，建议改成并行1，否则很慢）

?下图中，出现过问题的地方
1 ，database pre-install checks ,原因，没有database包
2，check OPMN port availab ,原因，设置了OS的分辨率没有重启
3，file systems，原因，上面的包不全，导致解压的包有些没有的

安装结束，后续其他配置，有空再做。
问题1 ，R12.2里面没有EBSapp.env这个文件，参考MOSHow To Automatically Set the Current Run or Patch Edition / File System for EBS 12.2 (Doc ID 1545584.1)，有个脚本，可以查看（需要配置下这个脚本里面的XMLfile路径）。
查看结果为：
[root@erptest 12.2.ins]# su - applprod
