2- Check the oracle home size
bash-3.2$ cd /u01/app/oracle/product/11.2.0/dbhome_1
bash-3.2$ du -sh .
4.2G .
3- Create the same directory tree on the remote server as the source server and change ownership to oracle user
bash-3.2# mkdir -p /u01/app/oracle/product/11.2.0/dbhome_1
bash-3.2# chown -R oracle:oinstall /u01
4- On source server execute tar command to copy over the network the oracle home directories to the target server
bash-3.2$ cd /u01/app/oracle/product/11.2.0/dbhome_1
bash-3.2$ tar cvf - . ( ssh lnx2 "cd /u01/app/oracle/product/11.2.0/dbhome_1 ; tar xvf -" )
5- On the target server once the tar command finishes to copy on the target oracle home check the total size and must be the same as the source server
bash-3.2$ cd /u01/app/oracle/product/11.2.0/dbhome_1
bash-3.2$ du -sh .
4.2G
6- Before starting clone process we need to detach the inventory because the server was itself a clone of the source
bash-3.2$ cd /u01/app/oracle/product/11.2.0/dbhome_1/oui/bin
bash-3.2$ ./runInstaller -detachHome ORACLE_HOME="/u01/app/oracle/product/11.2.0/dbhome_1"

The inventory pointer is located at /var/opt/oracle/oraInst.loc
The inventory is located at /u01/app/oraInventory
'DetachHome' was successful.
Using the OUI to finish the cloning process
7- Once the inventory was detached from the old server version I can run the cloning procedure
bash-3.2$ cd /u01/app/oracle/product/11.2.0/dbhome_1/oui/bin
bash-3.2$ ./runInstaller -clone -silent -ignorePreReq ORACLE_HOME="/u01/app/oracle/product/11.2.0/dbhome_1" ORACLE_HOME_NAME="dbhome_11gR2" ORACLE_BASE="/u01/app/oracle" OSDBA_GROUP=dba OSOPER_GROUP=dba
