Starting with 12c, running datapatch may be required after creating a database, depending on the database version and method for creating the database. Instead of having to remember all the variations, it’s much simpler just to run datapatch -prereq after creating the database.
I will demonstrate by creating RAC database for version 12.1 and 12.2. Both database homes have had the July 2019 patch applied.
Test case for 12.2.

Review the installation queue for 12.2 and 12.1 will show that the datapatch will need to be run for 12.1 to apply DATABASE BUNDLE PATCH 12.1.0.2.190716 for the newly created database.
In conclusion, it’s good practice to check datapatch prerequisites after creating a database to avoid any issues in the future.

HI Michael,
I believe the heading for “datapatch -prereq” for 12.1 DB version should be corrected.
Run datapatch -prereq for 12.1:
Thanks,
Devendra
Thanks Devendra and will have this corrected.
Thank you very much for this article!!
Most welcome.
