How to Modify parameters in an AWS RDS Parameter Group?

It is possible to modify parameter values in a customer-created DB parameter group; the parameter values in a default DB parameter group may not be changed at all. Any change you perform to parameters that are found in a customer-created DB parameter group will get applied to every single DB instance associated with this DB parameter group.

Changes to a few parameters get directly applied to the DB instance with no reboot. Some other parameters get their changes applied merely when the DB instance finishes its reboot. On the RDS console you are capable of checking the status of the DB parameter group which is associated with a specific DB instance using the Configuration tab. For instance, in case the DB instance was not utilizing the latest changes to its associated DB parameter group, you will find on the RDS console the DB parameter group having a “pending-reboot” as its status. For the sake of adding the most recent parameter changes to that DB instance, you will need to start rebooting it manually.

Using the Console

In order for you to modify an AWS RDS parameter group, go through the below steps:

1. Login to the AWS Management Console. Then, head straight to the Amazon RDS console using the following link https://console.aws.amazon.com/rds/.
2. From navigation pane, click on the option Parameter groups.
3. From the listed parameter groups, select which parameter group you’d like to modify.
