This article is to support customers of Relational DB Service, Lumen's database-as-a-service product. These instructions are specific to customizing your configuration settings for a MySQL-compatible instance through the Control Portal.


Lumen's Relational DB Service is a MySQL-compatible database-as-a-service that provides instant access to a database instance with SSL support, daily backups, basic monitoring and a replication option. Users can configure the amount of CPU, Memory, and Storage based on their database needs. They can choose to replicate their instance in datacenter for a more highly available solution. As the customer's capacity needs grown, they can easily scale their CPU, RAM, and/or Storage with the click of a button.

Creating a New Configuration Profile

  1. Browse to Lumen Cloud’s Relational DB UI through the Control Portal or directly at

  2. Click on the "Configuration Profiles" tab. From here, you will see the "MySQL Default" profile which is automatically assigned to all Relational DB instances, if a user-defined profile is not selected. You can also see any custom profiles that a user has created for your account.

  3. To create a new Configuration Profile, click the 'Configuration Profile' button, which opens a new screen with a list of all configurable parameters. Edit the parameters to meet your needs and click the 'create profile' button.

  4. At this point, your new Configuration Profile is not associated to any Relational DB instance. Please see next section for applying a custom Configuration Profile.

Applying Your Custom Configuration Profile

  1. You can apply a custom Configuration Profile to a new Relational DB instance at the time of creation. You can also do the same to an existing instance.

  2. To create a new Relational DB instance with an existing Configuration Profile, navigate to Lumen Cloud’s Relational DB UI through the Control Portal or directly at From the "Databases" tab, click on the green "+ database" button.

  3. When creating a new Relational DB instance, you are able to customize several options. Listed in the "Options" section of the UI, is a drop down box that includes all available "Configuration Profiles" for your account. Simply select the profile you would like to use before clicking on "Create Database".

  4. To change the Configuration Profile of an existing instance, select the database instance you would like to change in order to navigate to the details screen for that instance. Click on the "Configuration" tab to view the current profile that is applied, and click 'change'.

  5. Once you have selected to make a change, you are taken to a screen that allows you to either define a new profile or select an existing Configuration Profile from a drop-down box at the top. Select the new Configuration Profile you would like associated to the instance. In order for these changes to take effect, the database instance must be restarted! You are then asked to select whether to restart the database instance now or to manually restart later. Make the selection and click 'apply'.

  6. If you choose to restart later, the instance is flagged for restart until the restart occurs.

  7. When you are ready to restart, navigate to the details page for that instance by clicking on the instance from the main screen. From here, you can restart your instance.
