The Oracle Database Auto Upgrade utility is a new tiny little command line tool which allows you to upgrade your databases in an unattended way. I call it the Hands-Free Upgrade. The new Auto Upgrade utility in Oracle 19che idea of the tool is to run the prechecks against multiple databases, fix 99% of the potential issues, set a restore point in case something goes wrong – and then upgrade your databases. And of course, do the post upgrade, recompilation and time zone adjustment. The...
