ebs系統架構簡介9——Patch

1、什麼是codelines 和 codelevels？

在R12中，oracle Application 更新檔以codelines分組，R12.0對應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 的驅動檔案裡有什麼？

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更新檔是打在ebs各個子產品上的更新檔，簡單了解為把一些：forms、reports等拷貝到對應的子產品目錄下，還有sql對象拷貝到資料庫内，執行。

在打更新檔的過程中，會在更新檔存放的目錄（比如/home/apptest/1456321/）下，建立backup目錄，把需要修改或者替換的檔案拷貝到這個目錄下。

打這個更新檔，一直是關閉應用，enable維護模式後才進行的，資料庫開啟；

不過最近在網上及書上看到一些操作， 比如在版主zlc158的大作上看到安裝簡體中文語言包時， 操作步驟中沒有關閉應用，隻有修改

維護模式 ， adpatch 之後直接disable 維護模式。

關于adpatch的例子，參考：http://download.csdn.net/detail/changyanmanman/7442163

admrgpch：

這個可以合并多個更新檔，生成一個驅動檔案，然後打一次就了。

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
