Clone Oracle Applications

Posted by appsinfo on November 17, 2008

Clone Oracle Applications


There are three sections to this phase of the cloning process:


• Prepare the source system

• Copy the source system to the target system

• Configure the target system


Clone Oracle Applications


• Use Rapid Clone to create template files for cloning on the source system.

• After the source system is copied to the target system, Rapid Clone updates these templates to

contain the new target system configuration settings.

• Rapid Clone will not change the source system configuration.


Prepare the Source System


1. Prepare the source system database tier for cloning.

2. Prepare the source system application tier for cloning.


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 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 appsTier


Copy the Source System to the Target System


• Copy the application tier file system from the source Applications system to the target node.

• Ensure the application tier files copied to the target system are owned by the target applmgr

    user, and that the database tier files are owned by the oracle user.


Copy the Application Tier File System


• Log on to the source system application tier nodes as the applmgr user.

• Shut down the application tier server processes.

• Copy the following application tier directories from the source node to the target application       

   tier node:






         – <COMMON_TOP/clone>

         <806 ORACLE_HOME>

         <iAS ORACLE_HOME>


Copy the Database Tier File System


• Log on to the source system database node as the oracle user.

• Perform a normal shutdown of the source system database.

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

• Copy the source database ORACLE_HOME to the target system.

• Start up the source Applications system database and application tier processes.


Configure the Target System


1. Configure the target system database server.

2. Configure the target system application tier server



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 dbTier


 Configure the Target System Application Server Nodes


Log on to the target system as the applmgr user and type the following commands:

cd <COMMON_TOP>/clone/bin

perl appsTier


Finishing Tasks


1. Update profile options

Rapid Clone updates only site level profile options. If any other profile options are set to instance

specific values, you must update them manually.


2. Update printer settings

If the new cloned system needs to utilize different printers, update the target system with the new printer settings.


3. Update Workflow and other configuration settings Cloning an Oracle Applications instance will not update the host and instance specific information used by Oracle Workflow and other components
