Supported series

• Standalone Basic Version: Not supported for now (since the Standalone Basic Version has only one master node and no slave node).
• Dual-computer High-availability Version: Supports the RDS for MySQL; do not support RDS for SQL Server and RDS for PostgreSQL for now.
• Raft Financial Version: Not supported for now.

Considerations

Before switching

• Please select the low peak of service for switching.
• Persistent connection needs to be disconnected for master nodes, or persistent connection only supports read action without write action after the switching.
• There are no massive transactions for writing at master node, leading to long-term lock occupation and release failure.

During switching

• Master-slave switch might lead to services’ transient interruption and temporary write stop.

Action

1. Enter the “RDS - Instance List” page, click the instance name to enter the “Instance Details” page.
2. Enter the “Basic Information” page, view the “Node Information” module, and click “Master-slave Switch” for action.
