Step by Step Guide Upgrading Grid Infrastructure and RAC Database Silent Method from 12 2 0 1 to 19 3

YouTube video

Introduction

In this tutorial, we will cover the process of upgrading the Grid Infrastructure and RAC Database from version 12.2.0.1 to 19.3 using the silent method. The silent method is recommended when you have restricted access and cannot use the GUI-based upgrade method. Although the silent method can be more tiresome, it allows you to learn more about the upgrade process.

Please note that this tutorial assumes that the patch 28553832 has already been applied to the Oracle 12c home.

Key Points

  1. Upgrade should be done using the silent method when restricted access is present.
  2. The GUI-based upgrade method is recommended when available.
  3. The patch 28553832 must be applied before proceeding with the upgrade.
  4. Download and unzip the grid software on the first node only.
  5. Check the kernel version, RPMs, and minimum OS requirements before proceeding.
  6. Prepare the response file with the necessary configurations.
  7. Run the cluster verification utility to ensure everything is set up correctly.
  8. Run a dry run of the upgrade on the first node to test for any errors or warnings.
  9. Check and update the permissions of the root scripts if necessary.
  10. Run the actual upgrade of the Grid Infrastructure using the response file.

Step by Step Process

Step 1: Download and Unzip the Grid Software

First, download the Grid software and unzip it on the first node. Make sure to only perform this step on the first node.

Step 2: Check System Requirements

Before proceeding with the upgrade, check the kernel version, RPMs, and minimum OS requirements. These must be met in order to successfully upgrade the Grid Infrastructure and RAC Database.

Step 3: Prepare the Response File

Create a response file with the necessary configurations. Make sure to include the version, inventory location, and install option. Adjust other configurations as needed for your specific setup.

Step 4: Run the Cluster Verification Utility

Execute the cluster verification utility to check if everything is set up correctly. This utility will validate the cluster configuration and check for any errors or warnings. Make sure to resolve any issues before proceeding.

Step 5: Perform a Dry Run of the Upgrade

Before executing the actual upgrade, run a dry run to test for any errors or warnings. This will help you identify any potential issues and allow you to make necessary adjustments to the response file.

Step 6: Check and Update Root Script Permissions

After the dry run, check the permissions of the root scripts. If necessary, update the permissions to ensure they can be executed. This is a critical step to avoid any issues during the upgrade process.

Step 7: Execute the Upgrade

Finally, run the actual upgrade of the Grid Infrastructure using the prepared response file. This will launch the Oracle Grid Infrastructure setup wizard and guide you through the upgrade process. Make sure to monitor the log and resolve any issues that may arise.

Conclusion

In this tutorial, we have covered the step by step process of upgrading the Grid Infrastructure and RAC Database from version 12.2.0.1 to 19.3 using the silent method. By following these steps and ensuring all prerequisites are met, you can successfully upgrade your environment. Remember to always backup your data before performing any upgrade. Good luck with your upgrade process!
