By Mouhamadou Diaw<\/strong><\/p>\n

When deploying new Oracle Home on the same server or on a new server, you may use the downloaded Oracle binaries and do an install from scratch as usual. You may then apply any patch you have on your actually Oracle Homes. This may take time.
\nOracle provides tools to clone an existing Oracle Home with all patches on top on it. I usually use the famous clone.pl script, but does it still work with Oracle 21c?
\nI decide to do some tests on my small lab<\/p>\n

I actually have this following Oracle Home with the patch 33239276<\/p>\n

I decide to clone it in the same server using the traditional clone.pl script<\/p>\n

1- Copy the binairies in db_1 in the new db_2 Oracle Home. Feel free to proceed as you like (zip, cp, tar\u2026). Just adjust the permissions as they are on db_1<\/p>\n

But as we can see the clone.pl is deprecated, Oracle recommends performing a Software Only installation from the image. How this process does work?
\nLet\u2019s see this method<\/p>\n

1- Let\u2019s create the gold image using the runInstaller command as below<\/p>\n

From the source Oracle Home<\/p>\n

Launching Oracle Database Setup Wizard...<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

The wizard should run following images<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

If you do not have a graphical environment configured or do not want to use the graphical tool, just use the silent option in the command<\/p>\n

2- Let\u2019s now use the goldimage to deploy a new Oracle Home<\/p>\n

The first step is to unpack the goldimage on the new Oracle Home folder<\/p>\n

And after we can start the deployment with the runInstaller in the new Oracle Home<\/p>\n

The install process is the same that usual ( But here we will not need to install the eventual patches as they are already in the GoldImage). I will not show all screenshots for the install<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

And at the end of the installation, we can verify that the new Oracle Home has the same patch level<\/p>\n

Note that here also you can use a silent install if you do not have or do not want graphical tool<\/p>\n

We can also validate that the Oracle Inventory is fine<\/p>\n
