Applying for and Changing a Private Domain Name

Constraints

• Changing the private domain name will interrupt your database connection. To reconnect to the instance, change the connection address of your applications. The new private domain name is applied to the instance about 5 minutes after the change.
• If your DB instance is connected through a private domain name, changing its floating IP address does not interrupt services.

Procedure

When you buy a DB instance, the system automatically assigns a private domain name to your instance.

After the DB instance is created, you can change the private domain name as needed.
