Clone Oracle Home – move to a new location

The most efficient way to create/duplicate/move oracle software is to clone an existing Oracle Home with all applied patch inside. Oracle provide a Perl script as $ORACLE_HOME/clone/bin/clone.pl. It accepts ORACLE HOME and ORACLE HOME NAME as parameters.

Demo:

Current Oracle Home: /u01/app/oracle/db

New Oracle Home: /app/oracle/db

1) Package current ORACLE_HOME as ‘oracle’ user

$> cd /u01/app/oracle/db

$> tar cvf orahome.tar *

2) Extract the package to new ORACLE_HOME

$> cd /app/oracle/db

$> tar xvf orahome.tar

3) Call clone.pl script to clone a new ORACLE HOME

$> export ORACLE_BASE=/app/oracle

$> export ORACLE_HOME=/app/oracle/db

$> export PATH=${ORACLE_HOME}/bin:$PATH

$> perl ${ORACLE_HOME}/clone/bin/clone.pl ORACLE_HOME=/app/oracle/db ORACLE_HOME_NAME=OraDb10g_home2

./runInstaller -silent -clone -waitForCompletion  "ORACLE_HOME=/app/oracle/db" "ORACLE_HOME_NAME=DbOra10g_Home2" -noConfig -nowait
