Switch a vSwitch

Considerations

• ApsaraDB MyBase for MySQL instances with ESSDs support switching the VPC and vSwitch.

• ApsaraDB MyBase for MySQL instances with local SSDs support switching only the vSwitch.

Impacts

• This operation causes a transient interruption of about 30 seconds. Ensure your application can automatically reconnect.

• Switching the vSwitch changes the virtual IP address (VIP). We recommend using the endpoint to connect to your instance, instead of the IP address.

• The VIP change temporarily affects Data Management (DMS) and Data Transmission Service (DTS). These services return to normal automatically after the switch is complete.

• Client-side caching may prevent writes. Clear the cache promptly.

Procedure

1. Log on to the ApsaraDB for MyBase console.

5. In the left-side navigation pane, click Database Connection.
