Restart a zone

This topic describes how to restart a zone. Restarting a zone also restarts all OBServer nodes in the zone. Proceed with caution.

Prerequisites

• Make sure that you have the following permissions:

  • Resource Permissions : Cluster Maintenance permission
  • Menu Permissions : Permission on the Overview menu of Clusters

• The target OceanBase cluster is managed in the current OCP cluster.

  Otherwise, you need to use the current OCP cluster to take over the OceanBase cluster. For more information, see Take over a cluster.

Procedure

1. Log on to the OCP console.

2. In the left-side navigation pane, click Clusters to go to the Clusters page.

3. In the Clusters list on the page, find the target cluster and click its name.

4. In the Zones list, find the row of the target zone and choose More > Restart in the Actions column.

   

5. In the dialog box that appears, specify whether to initiate a minor compaction before stopping the observer process, and click Restart . By default, this option is selected.

   A minor compaction prolongs the response time required to stop the observer process, but significantly shortens the time required to restore the OBServer node.

6. In the dialog box that appears, click View Task to view the progress.

   You can also choose System Management > Tasks to view the progress.

   When the task enters the Completed state, and the status of the zone is displayed as Running in the Zones list on the Overview page, the zone is restarted.
