When you use a PolarDB-X 1.0 database, you need to access the storage-layer RDS instance. If the network configuration of the storage-layer RDS instance changes, such as by switching zones, the network connectivity between PolarDB-X 1.0 and the storage-layer RDS instance is disrupted. This makes the PolarDB-X 1.0 database inaccessible, and you must repair the network connection. This topic describes how to manually repair database shard connections in the PolarDB-X 1.0 console.
Procedure
-
Log on to the PolarDB-X 1.0 console.
-
In the top navigation bar, select the region where the instance is deployed.
-
In the left-side navigation pane, click Instances.
- Find the target instance and click its instance ID.
- In the left-side navigation pane, choose .
- In the list of databases, find the target database and click its name.
- On the Basic Information page, in the Shortcuts section, click Fix Database Shard Connections.
- In the dialog box that appears, click OK.
