This blog post describes the process of cloning an Oracle Home - in this case we are cloning a 11g Release 2 Oracle Home from source machine devastator to target machine vixen.
On source (devastator)
ORACLE_HOME location is : /u01/app/oracle/product/11.2.0/dbhome_1
Go to directory on source machine one level higher and tar the db_home1 directory and all sub-directories
devastator:$ pwd
devastator:$ /u01/app/oracle/product/11.2.0
devastator:$ tar -cvf 11gr2.tar dbhome_1
On Target (vixen)
Create the directory /u01/app/oracle/product/11.2.0 if it does not exist
On Source
scp or ftp the tar file to this location on the target machine
devastator:$ scp -rp 11gr2.tar oracle@vixen:/u01/app/oracle/product/11.2.0
On target
Uncompress the tar file
vixen:$ cd /u01/app/oracle/product/11.2.0
vixen:$ tar -xvf 11gr2.tar
Clone the Oracle Home using the perl script clone.pl which is located under the $ORACLE_HOME/clone/bin
vixen:$ cd /u01/app/oracle/product/11.2.0/dbhome_1/clone/bin
vixen:$ perl clone.pl ORACLE_BASE=/u01/app/oracle ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1 ORACLE_HOME_NAME=11GR2_HOME
./runInstaller -clone -waitForCompletion "ORACLE_BASE=/u01/app/oracle" "ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1" "ORACLE_HOME_NAME=11GR2_HOME" -silent -noConfig -nowait

Starting to execute configuration assistants
The following configuration assistants have not been run. This can happen because Oracle Universal Installer was invoked with the -noConfig option.
--------------------------------------
The "/u01/app/oracle/product/11.2.0/dbhome_1/cfgtoollogs/configToolFailedCommands" script contains all commands that failed, were skipped or were cancelled. This file may be used to run these configuration assistants outside of OUI. Note that you may have to update this script with passwords (if any) before executing the same.

WARNING:
The following configuration scripts need to be executed as the "root" user.
/u01/app/oracle/product/11.2.0/dbhome_1/root.sh
To execute the configuration scripts:
1. Open a terminal window
2. Log in as "root"
3. Run the scripts
The cloning of 11GR2_HOME was successful.
Please check '/u01/app/oracle/oraInventory/logs/cloneActions2012-06-28_12-19-47PM.log' for more details.
Run the root.sh script as root
# pwd
/u01/app/oracle/product/11.2.0/dbhome_1
# ./root.sh
Check /u01/app/oracle/product/11.2.0/dbhome_1/install/root_devastator_2012-06-29_07-42-31.log for the output of root script

Running Oracle 11g root.sh script...
The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /u01/app/oracle/product/11.2.0/dbhome_1
Entries will be added to the /var/opt/oracle/oratab file as needed by
Database Configuration Assistant when a database is created
Finished running generic part of root.sh script.
Now product-specific root actions will be performed.
Finished product-specific root actions.
We can now check that the OraInventory has been updated with the 11g Release 2 Oracle Home details.
On this machine, earlier there was only a 10g Oracle Home installed. When we check the contents of the inventory.xml file, we will see that it has information about the 11g Oracle Home – 11GR2_HOME
vixen:$ cat /var/opt/oracle/oraInst.loc
inventory_loc=/u01/app/oracle/oraInventory
inst_group=dba
vixen:$cd /u01/app/oracle/oraInventory
vixen:$ ls
backup ContentsXML logs oraInstaller.properties oui
Contents install.platform oraInst.loc orainstRoot.sh sessionContext.se
vixen:$cd ContentsXML
vixen:$ ls
comps.xml inventory.xml libs.xml
vixen:$ vi inventory.xml
<?xml version="1.0" standalone="yes" ?>

Conclusion:
This is the step to be followed for clone oracle binary software for all versions of Oracle.
