Applying for and Changing a Private Domain Name for a Database Proxy

Scenarios

After a database proxy is created, you can apply for a private domain name for it and change the domain name later as needed.

Precautions

• To use a private domain name for a database proxy, you need to contact customer service to apply for required permissions.
• The private domain name must be unique in a given region.
• Changing the private domain name for a database proxy will interrupt your database connection. To reconnect to the proxy, change the connection address of your applications. The new private domain name is applied to the proxy about 5 minutes after the change.
