Starting from Oracle19c cloning your oracle home is a bit different, whether you use this method for out of place patching or rolling out patches to multiple servers we no longer use clone.pl, instead oracle recommends using the software-only install option, available in the runInstaller command. Below are the steps to follow for a RAC environment:

Here are my environment details:

ORACLE_HOME = /u01/app/oracle/product/19.0.0/db_1 
CLONED_ORACLE_HOME = /u01/app/oracle/product/19.0.0/db_clone 
RAC NODES = rac1, rac2 

1. Go to your oracle home and execute the runInstaller command, setting your destinationLocation to where the image will be saved.

# cd $ORACLE_HOME
# ./runInstaller -createGoldImage -destinationLocation
/u01/app/oracle/product/19.0.0

If you don’t have x11 forwarding enabled just add -silent to the command.

# ./runInstaller -silent -createGoldImage -destinationLocation $PATH

2. Unzip the image to your new oracle home 

# cd /u01/app/oracle/product/19.0.0
# ls -l
drwxr-xr-x. 69 oracle oinstall 4096 May 11 15:46 db_1
drwxr-xr-x. 68 oracle oinstall 4096 May 18 15:58 db_clone
-rw-r--r--. 1 oracle oinstall 3068280989 May 18 15:49
db_home_2021-05-18_03-46-32PM.zip


# unzip db_home_2021-05-18_03-46-32PM.zip -d
/u01/app/oracle/product/19.0.0/db_clone

3. Go to the new oracle home and execute the runInstaller then follow the GUI or using the silent install.

Using the GUI

# cd /u01/app/oracle/product/19.0.0/db_clone
# ./runInstaller

g. Once done, if you didn’t have the root password, the installer will have you run the root.sh script on both nodes

Using the silent installation

a. Execute the runInstaller command with the below parameters

# ./runInstaller -ignorePrereq -silent \
oracle.install.option=INSTALL_DB_SWONLY \
UNIX_GROUP_NAME=oinstall \
ORACLE_HOME=/u01/app/oracle/product/19.0.0/db_clone \
ORACLE_BASE=/u01/app/oracle \
oracle.install.db.InstallEdition=EE \
oracle.install.db.OSDBA_GROUP=dba \
oracle.install.db.OSOPER_GROUP=dba \
oracle.install.db.OSBACKUPDBA_GROUP=dba \
oracle.install.db.OSDGDBA_GROUP=dba \
oracle.install.db.OSKMDBA_GROUP=dba \
oracle.install.db.OSRACDBA_GROUP=dba \
oracle.install.db.CLUSTER_NODES=rac1,rac2 \
