1. Why Cloning Oracle APPS environment ?

  - Changing the Oracle APPS architecture (adding a node to the system)

  - Migrating an existing system to new hardware

  - Creating a copy of the production system for testing, development 

  - Creating a stage area to reduce patching downtime

2. Cloning Prerequisites

• Verify source and target nodes software versions (if is not done already)

• Apply the latest AD Minipack (if is not done already)

• Apply the latest AutoConfig Template patch (if is not done already)

• Apply the latest Rapid Clone patches (if is not done already)

• Setup Rapid Clone on the Applications Tier (if is not done already)

• Setup Rapid Clone on the Database Tier (if is not done already)

• Maintain Snapshot information

3. Cloning Oracle Applications 11i (using Rapid Clone)

• Prepare the Source System

Prepare the source system database tier for cloning 
Log on to the source system as the ORACLE user and run the following commands:

 

cd <RDBMS ORACLE_HOME>/appsutil/scripts/<CONTEXT_NAME>
perl adpreclone.pl dbTier 

Prepare the source system application tier for cloning 
Log on to the source system as the APPLMGR user and run the following commands on each node that contains an APPL_TOP:

cd <COMMON_TOP>/admin/scripts/<CONTEXT_NAME>
perl adpreclone.pl appsTier 

• Copy the Source System to the Target System

         Shutdown the APPS services and database services and copy to the target system the following directories: 

         -- For APPS tier:

 <APPL_TOP> 
<OA_HTML> 
<OA_JAVA> 
<OA_JRE_TOP> 
<COMMON_TOP>/util 
<COMMON_TOP>/clone 
<COMMON_TOP>/_pages (when this directory exists) 
<806 ORACLE_HOME> 
<iAS ORACLE_HOME> 

       -- For Database tier:

Copy the database (DBF) files from the source to the target system 
Copy the source database ORACLE_HOME to the target system 

• Configure the Target System

Configure the target system database server
Log on to the target system as the ORACLE user and type the following commands to configure and start the database:

cd <RDBMS ORACLE_HOME>/appsutil/clone/bin
perl adcfgclone.pl dbTier 

Configure the target system application tier server nodes
Log on to the target system as the APPLMGR user and type the following commands:

cd <COMMON_TOP>/clone/bin
perl adcfgclone.pl appsTier

4. Complete the cloning process

• Update profile options

• Update printer settings

• Update workflow configuration settings

• Verify the APPLCSF variable setting: Source the APPS environment and show the $APPLCSF variable (used to point to the top-level directory for concurrent manager log and output files). If needed change the value of s_applcsf in the contextfile using OAM and then run AutoConfig

• Update the SESSION_COOKIE_DOMAIN value in ICX_PARAMETERS (only if the source and target domains are different and the value of the parameter is not null in the source system)

5. Cloning: Remarks

• For more documents please refer to the Metalink Doc. ID 230672.1

• In the first releases of Rapid Clone there are some bugs: please assure that AD utilities, AutoConfig templates and Rapid Clone are up-to-date;

• Run adpreclone just before you will copy the files (Is not good if there are any physical modification on the database side between running adpreclone and copying the files needed for the clone);  

• For Sharing the Application Tier File System in Oracle E-Business Suite 11i please refer to the Metalink Doc. ID 233428.1
