1、什么是codelines 和 codelevels？

在R12中，oracle Application 补丁以codelines分组，R12.0对应codeline A。Any future point releases introduce new codelines, each identified by a new letter.  For example, Release 12.1 would introduce codeline B and Release 12.2 would introduce codeline C.  

Patches associated with codelines not only implement a set of product features for that point release, but also provide fixes to that set of features. We describe this unique set of product features for a point release as a codelevel and assign it a unique number. Codelevels also identify patches for individual products. 

For example, codelevel R12.AD.A.1 is the first set of fixes to codelevel R12.AD.A, 

R12.AD.A.2 is the second set, and so on. 

Codelevels are cumulative（累加的） - each one contains the initial set of features plus all the fixes created to date for that product or product family.

All codelevels created after the initial point release are aggregated into cumulative release update packs (RUPs). RUP1 is equivalent to R12.0.1, RUP2 is equivalent to R12.0.2, and so on.  In addition, they may also provide feature enhancements, which provide new functionality that has a limited impact on your system.

A new point release contains new features that will substantially impact your system and may change its operation.  It starts a new codeline (for example, codeline B).  At that point, you can choose to upgrade to the new codeline and adopt the new features, or stay on your existing codeline, where bug fixes and enhancements will continue to be provided for your existing features.

2、patch 的驱动文件里有什么？

The driver actions are as follows:

• Copy: Contains commands to change Oracle Applications files. The commands include directives to copy and update files, libraries, and/or Java, and commands for generating JAR files and/or C executables. In a multi-node system, the copy portion runs on all application tier APPL_TOPs.
• Database: Contains commands to change Oracle Applications database objects,such as PL/SQL and table definitions, or to update or migrate data. In a multi-node system, the database portion runs only on the application tier APPL_TOP that implements the administration server.
• Generate: Contains commands to generate forms, reports, messages, and/or graphics files. In a multi-node system, the generate portion runs on all application tier APPL_TOPs, unless the APPL_TOP only implements the administration server.

adpatch

adpatch补丁是打在ebs各个模块上的补丁，简单理解为把一些：forms、reports等拷贝到对应的模块目录下，还有sql对象拷贝到数据库内，执行。

在打补丁的过程中，会在补丁存放的目录（比如/home/apptest/1456321/）下，创建backup目录，把需要修改或者替换的文件拷贝到这个目录下。

打这个补丁，一直是关闭应用，enable维护模式后才进行的，数据库开启；

不过最近在网上及书上看到一些操作， 比如在版主zlc158的大作上看到安装简体中文语言包时， 操作步骤中没有关闭应用，只有修改

维护模式 ， adpatch 之后直接disable 维护模式。

关于adpatch的例子，参考：http://download.csdn.net/detail/changyanmanman/7442163

admrgpch：

这个可以合并多个补丁，生成一个驱动文件，然后打一次就了。

Create Source and destination directory
Copy all the patche to source directory
and run the below scripts
admrgpch -s /home/appltest/source -d /home/appltest/dest -merge_name mergedrv

例子：

[appl01@vs123 patch]$ admrgpch -s /u01/patch/merge -d /u01/patch/dest -merge_name mergedrv
