PolarDB:Fix database shard connections

Last Updated:Jun 20, 2026

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

  1. Log on to the PolarDB-X 1.0 console.

  2. In the top navigation bar, select the region where the instance is deployed.

  3. In the left-side navigation pane, click Instances.

  4. Find the target instance and click its instance ID.
  5. In the left-side navigation pane, choose Configuration and Management > Databases.
  6. In the list of databases, find the target database and click its name.
  7. On the Basic Information page, in the Shortcuts section, click Fix Database Shard Connections.
  8. In the dialog box that appears, click OK.
