1)Introduction
2)Apply the latest rapid clone patch
3)Prepare the application source system
4)Copy file system from source to target system
5)Clone the target system
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
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
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/
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)
I)
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
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.

First Creating a new context file for the cloned system.
The program is going to ask you for information about the new system:
Provide the values required for creation of the new Database Context file.
Do you want to use a virtual hostname for the target node (y/n) [n] ?:
Target instance is a Real Application Cluster (RAC) instance (y/n) [n]:
Target System database name [test]:DEV
Target system RDBMS ORACLE_HOME directory [/preprod/u01/dbtire/testdb/9.2.0]:/crp1/devmgr/DEV/devdb/9.2.0
Target system utl_file accessible directories list [/usr/tmp]:
Number of DATA_TOP's on the target system [1]:
Target system DATA_TOP 1 [/preprod/u01/dbtire/testdata]:/crp1/devmgr/DEV/devdata
Do you want to preserve the Display set to ka01axsd2:0.0 (y/n) [y] ?:
Clone Context uses the same port pool mechanism as the Rapid Install
Once you choose a port pool, Clone Context will validate the port availability.
Enter the port pool number [0-99]: 4
