Introduction:
Cloning creates an identical copy of an existing Oracle Applications system. There are various reasons for cloning an Oracle Applications system such as: Creating a copy of the production system for testing updates. Migrating an existing system to new hardware. Creating a stage area to reduce patching downtime

Apply the latest rapid clone patch
Apply the latest Rapid Clone patches update the Oracle Applications file system with the latest Rapid Clone files by applying the following patches to all application tier server nodes: Please follow the Metalink Note:230672.1 a. 4709948 b. 5225940 c. 3453499

Prepare the Source System Execute the following commands to prepare the source system 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: ( owner of the database user, for us it’s a applmgr)
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

Here apps password will ask and please put the apps password here.

E) Shutdown application i.e shutdown all the services of the source instance, Change to the directory to the cd $COMMON_TOP/admin/scripts/<CONTEXT_NAME> ( /preprod/u01/appstire/testcomn/admin/scripts/test_ka01axsd2) F) Log on to the source system as applmgr and shutdown database (normal shutdown) SQL> shutdown

Copy the Source System to the Target System Copy the application tier file system from the source Applications system to the target node by executing the following steps in the order listed. Login as root and copy all five top i.e APPL_TOP, COMMON_TOP,ORA_TOP,DATA_TOP,DB_TOP( i.e testappl, testcomn. testora,testadata,testdb dir from sourve m/c to destination m/c) # Login to the source system’s # cp -rf /preprod/u01/appstier/testappl . & # cp -rf /prep/preprod/u01/appstier/testcomn . & # cp -r /preprod/u01/appstier/testappl/testdb

H) Log on to the target system as root and change the owner of all the above dir #chown -R devmgr:dba testappl and move testappl dir to devappl as below # mv testappl devappl ( do all the dir)

Configure the Target System Execute the following commands to configure the target system. You will be prompted for the target system specific values (SID, Paths, Ports, etc)

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

{e.g Log on to the target system as applmgrr and run the following command II) (DO FIRST at DB TIER) ,go to db tier's home i.e ORACLE_HOME/appsutil/clone/bin and run the adcfgclone.pl dbTier $ cd /crp1/devmgr/DEV/testdb/9.2.0/appsutil/clone/bin # ls -l total 432 -rwx--x--x 1 devmgr dba 36519 Dec 03 11:15 adcfgclone.pl -rwxr-xr-x 1 devmgr dba 3273 Dec 03 11:15 adchkutl.sh -rwxr-xr-x 1 devmgr dba 93301 Dec 03 11:15 adclone.pl -rwxr-xr-x 1 devmgr dba 29104 Dec 03 11:15 adclonectx.pl } J) Run adcfgclone.pl command at the DB TIER and answer all the question as below $ perl adcfgclone.pl dbTier Enter the APPS password [APPS]:  enter the apps password here. apps First Creating a new context file for the cloned system. The program is going to ask you for information about the new system:
