1. Take tar backup of existing Oracle home.

tar -cvzf OH_BINARIES_BKP.tar.gz /u01/app/oracle/product/11204/dbhome_1/*

2. untar the backup tar file in step1 with Target Oracle home and target owner

mkdir -p /u01/app/oracle/product/11204/dbhome_2
cd /u01/app/oracle/product/11204/dbhome_2
tar -xvzf/u01/app/oracle/product/11204/OH_BINARIES_BKP.tar.gz .

3. Post steps to be performed on both the nodes. 

cd /u01/app/oracle/product/11204/dbhome_2/clone/bin 
./clone.pl ORACLE_HOME=/u01/app/oracle/product/11204/dbhome_2 ORACLE_HOME_NAME=11204_dbhome_2 ORACLE_BASE=/u01/app/oracle

4. Update the cluster nodes 

Repeat step1 to step3 on all cluster nodes and run below commands

/u01/app/oracle/product/11204/dbhome_2/oui/bin/runInstaller -updateNodeListORACLE_HOME=/u01/app/oracle/product/11204/dbhome_2 "CLUSTER_NODES={npexdbadm01, npexdbadm02}"

5. Enable on rds protocol on oracle Home (Applicable only for Oracle homes in EXADATA machine) 

export ORACLE_HOME=/u01/app/oracle/product/11204/dbhome_2

cd $ORACLE_HOME/rdbms/lib
make -f ins_rdbms.mk ipc_rdsioracle

6. To check if the Binaries are RAC Enabled: (Applicable only for RAC)

cd $ORACLE_HOME/rdbms/lib
nm -r libknlopt.a | grep -c kcsm.o
1 >>> means RAC feature enabled 
0 >>> means RAC feature NOT enabled 

cd $ORACLE_HOME/rdbms/lib
make -f ins_rdbms.mk rac_onioracle

7. Verification:

/u01/app/oracle/product/11204/dbhome_2/OPatch/opatchlsinventory

 cat /u01/app/oracInventory/Context/inventory.xml  
>>> Verify Target OH is having all the cluster nodes
