If a host in an ApsaraDB MyBase dedicated cluster has performance problems or other problems, you can restart the host on the Hosts page.

Prerequisites

A host is created in the ApsaraDB MyBase for SQL Server dedicated cluster. For more information, see Create hosts in an ApsaraDB MyBase for SQL Server dedicated cluster.

Procedure

  1. Log on to the ApsaraDB MyBase console.
  2. In the upper-left corner of the page, select the region where you want to create a dedicated cluster.
  3. In the left-side navigation pane, click Hosts.
  4. Find the host that you want to restart, and click More > Restart Host in the Actions column.
  5. On the Restart Host page, click Restart.
    Note
    • When the host is restarted, the primary instance that runs on the host becomes the secondary instance on anther host after a primary/secondary switchover. During the switchover, one or two transient connections may occur.
    • The time required to restart the host varies based on the duration of the primary/secondary switchover.
    • If the host is restarted when an instance is being created or migrated, a longer time is required to create or migrate the instance.
