Starting 18c, the software zip file from Oracle contains the Oracle Home itself, means its already extracted and you can unzip it in the required folder where the intended folder to be a oracle home. The installation process just Relinks it. This facilitates the faster Oracle Home provisioning and rapid deployments.
Two Important changes in terms of Installation procedure.
Firstly, I have uncompressed the software mistakenly into /home/oracle and that became my home, In installation process the oracle home was never asked.
Installation process does not contain extracting software or copying Oracle Home step, just contain relink step
Secondly, Unlike we run runInstaller from extracted folder we should run dbsetup.sh and gridSetup.sh so it invoke the Installer.
In next post I will cover the Installation of 18c grid infrastructure software.
