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 submit a service ticket to request 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.
