2. Check the ORACLE_HOME size[ SOURCE DB]

cd $ORACLE_HOME
du -h . | tail -1
  14G   .

3. Create the ORACLE_HOME directory [TARGET HOST]

mkdir -p /oracle/app/oracle/product/12.1.0.2_clone/dbhome_1

4. Take ORACLE_HOME binary backup [ SOURCE HOST]

cd $ORACLE_HOME

tar -cvf /export/home/oracle/HOME_BKUP/home12_bkp.tar .

5. Scp the tar file to target host

cd /oracle/app/oracle/product/12.1.0.2_clone/dbhome_1
scp oracle@192.168.2.3:/export/home/oracle/HOME_BKUP/home12_bkp.tar .

6 . Untar the tar file

cd /oracle/app/oracle/product/12.1.0.2_clone/dbhome_1

tar -xvf home12_bkp.tar

7 . Run the clone script[TARGET HOST]

cd $ORACLE_HOME/oui/bin
./runInstaller -clone -silent -ignorePreReq ORACLE_HOME="/oracle/app/oracle/product/12.1.0.2_clone/dbhome_1"
ORACLE_HOME_NAME="dbhome_12gR2"
