ApsaraDB RDS:Change the vSwitch

Prerequisites

The RDS instances uses the subscription or pay-as-you-go billing method.

Impacts

• When you switch your RDS instance to a different vSwitch, a transient connection that lasts approximately 30 seconds occurs. Make sure that your application is configured to automatically reconnect to your RDS instance.

• After the vSwitch of your RDS instance is changed, the virtual IP addresses (VIPs) of your RDS instance change. We recommend that you connect your application to your RDS instance by using an endpoint. For more information, see Configure endpoints for an ApsaraDB RDS for PostgreSQL instance.

• Any change to the VIP will affect the availability of your RDS instance for a short period of time. Refresh and view the connection information in the ApsaraDB RDS console.

• VIP changes interrupt the connection between your RDS instance and Data Management (DMS) and the connection between your RDS instance and Data Transmission Service (DTS) for a short period of time. After the VPC and vSwitch of your RDS instance are changed, the connections are automatically resumed.

• If the DNS cache exists on your database client, you can read data but cannot write data. We recommend that you clear the cache on the client at the earliest opportunity.
