Changing Your Database Username
The MySQL username is defined by the lcp-secret-database-user secret and can be changed at any time. When this value is changed, a user with the new credentials is created in your database, and the previous username is removed when the service restarts.
However, before changing the secret’s value, you can add the current username to a list of retained users using the LCP_DATABASE_USER_WHITELIST variable. User credentials added in this way are retained and remain associated with your database even after the service is updated with a new secret value.
Keep in mind that changing the username can affect other services connected to the database, such as the liferay and backup services. These services must also restart when the database username is changed to continue working.
If no database username secret exists, then your Project service uses the LCP_MASTER_USER_NAME variable. This variable is defined in the LCP.json file and uses dxpcloud as its default value.
Retaining Database Usernames
Follow these steps to retain the current username by adding it to the list of retained users:
Go to the dedicated database service page in the desired Project environment.
Click on the Environment Variables tab.
Enter
LCP_DATABASE_USER_WHITELISTunder Regular variables, and enter the username you want to retain as its value. You can enter multiple usernames by separating with with a space and/or comma.Click on Save Changes.
Once saved, the database service automatically restarts and adds the current credentials to the list of retained users. After the service has finished restarting, proceed to change the lcp-secret-database-user secret.

You can optionally select which users can view the secret value, as well as which services use the secret.
Use the Publish secret checkboxes to acknowledge the impact of your changes on connected services.
Click on Publish Changes.
Once published, all connected services restart and stop receiving requests for some minutes. They may also behave differently depending on the secret’s usage. When the service starts up, the environment variables are read and the database user is updated.
