Steps to install Oracle 19c database with unzip software location.
Oracle 19c is having some changes in installation process. First, we need to setup the software location and unzip the software to that location because Oracle 19c will use that location as software location permanently. Oracle modified these process it will take less time to install the Oracle 19c software and easy to use these software by copy paste to other location.
- Create the folder where you keep and use the software location. I created as E:\Oracle\19.3.0\dbhome_1.
- Unzip the Oracle 19c software in the upper created dbhome location. It will extract all your software binaries to E:\Oracle\19.3.0\dbhome_1.
