If a host in an ApsaraDB MyBase dedicated cluster has performance problems or other
problems, you can restart the host on the Hosts page.
Procedure
- Log on to the ApsaraDB MyBase console.
- In the upper-left corner of the page, select the region where you want to create a
dedicated cluster.
- In the left-side navigation pane, click Hosts.
- Find the host that you want to restart, and click in the Actions column.
- 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.
