Step-by-Step Installation of Oracle Database 19c Software

Unzip the Software:
As the Oracle user, navigate to the directory where the Oracle software is downloaded. Unzip the software to the Oracle home directory, then run the installer using ./runInstaller

Start the Installation: Software Only

Screen 1: Select Configuration Option

Select the “Setup Software Only” option, then click the “Next” button.

Screen 2: Select the Database Installation Option

Select the “Oracle Real Application Cluster (RAC) Database Installation” option, then click “Next.”

Screen 3: Select List of Nodes

Select the nodes where the installer should install the Oracle RAC or Oracle RAC One, and then click “Next.”

Note: You can set up the SSH connectivity here. If you don’t, the next step will validate the connectivity and report any errors found.

Screen4: Select the Database Edition

Choose the edition type. I recommend selecting “Enterprise Edition,” but feel free to choose the one that best fits your environment.

Screen 5: Specify Installation Location

Ensure that the base and home directories are configured correctly.

Screen 6: Privileged Operating System Groups

Choose the appropriate group according to your configuration and environment

Screen 7: Root Script Execution and Configuration

I’ll uncheck the option to run the root scripts automatically and will execute them manually later. Click the Next button to continue.

Screen 8: Perform Prerequisite Checks

Since I haven’t set up the SCAN and DNS configurations yet, I’ll ignore this step for now. I’ll share the DNS configuration details soon. Click “Next” to continue.

Screen 9: Summary

Review the installation summary to ensure all settings are correct. Once you have verified the details, click the Install button to begin the installation process.

Congratulations! The installation has been completed successfully.
