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

"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.

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/cloneActions2010-06-28_12-19-47PM.log'
for more details.
Run
the root.sh script as root
# pwd

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

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

vixen:$cd

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