How to clone an Oracle Home in 19c

How to clone an Oracle Home in 19c

In Oracle 19c the way that we clone an Oracle Home has changed. Before you had to zip or tar the original ORACLE_HOME , untar to the desired location and use the script clone.pl. So it you try to use it in 19c you will get the message below:

[oracle@reneace01 ]$ /u01/app/oracle/product/19.0.0.0/dbhome_2/perl/bin/perl  /u01/app/oracle/product/19.0.0.0/dbhome_2/clone/bin/clone.pl  \
> ORACLE_BASE=/u01/app/oracle \
> ORACLE_HOME=/u01/app/oracle/product/19.0.0.0/dbhome_2 \
> ORACLE_HOME_NAME=db_19 \
> OSDBA_GROUP=dba \
> OSOPER_GROUP=dba

[INFO] [INS-32183] Use of clone.pl is deprecated in this release. Clone operation is equivalent to performing a Software Only installation from the image.
You must use /u01/app/oracle/product/19.0.0.0/dbhome_2/runInstaller script available to perform the Software Only install. For more details on image based installation, refer to help documentation.

Now in Oracle 19c we create a gold image to a backup location

[oracle@reneace01 ]$ echo $ORACLE_HOME
/u01/app/oracle/product/19.0.0.0/dbhome_1
[oracle@reneace01 ]$ $ORACLE_HOME/runInstaller -silent  -createGoldImage -destinationLocation /u01/software/19c_dbhome
Launching Oracle Database Setup Wizard...

Successfully Setup Software.
Gold Image location: /u01/software/19c_dbhome/db_home_2020-03-23_03-28-40PM.zip

Once you have created a gold image, you now unzip it to your new ORACLE_HOME

[oracle@reneace01 ]$ unzip -q /u01/software/19c_dbhome/db_home_2020-03-23_03-28-40PM.zip -d /u01/app/oracle/product/19.0.0.0/dbhome_2
[oracle@reneace01 ]$ unset ORACLE_HOME
[oracle@reneace01 ]$ unset ORACLE_SID
[oracle@reneace01 ]$ unset ORACLE_RSID
[oracle@reneace01 ]$ unset ORACLE_UNQNAME

As you can see , it is different as to how we use to clone in previous versions, but by no means more complex.
