Oracle 19c - Automation and Manageability Enhancements

Introduction
DBAs should always aim to automate their tasks and avoid as much as possible manual repetitive tasks. This was always true; however, not always implemented; now with the new DevOps era, I see more and more Database teams who have been "hit" by the DevOps trend which demands more automation and collaboration in order to accelerate application updates & delivery

DBCA Silent Mode 
One of the common and popular ways to achieve automation when it comes to installation, configuration, and patching, is to leverage Oracle DBCA (Database Configuration Assistant) tool with the silent mode which is basically and alternative to the regular "GUI" mode DBCA.
When using silent mode, customers can run scripts that will handle a require operation without manual process which requires the "traditional" GUI mode.
