Manage Clusters

DBCC supports modifying the cluster name, enabling maintenance mode, and deleting clusters.

Access the cluster management page

  1. Log into the DBCC console.

  2. Click the cluster name in the top-right corner of the console.

  3. Select Clusters from the dropdown menu to enter the cluster management page.

Modify cluster name

  1. On the Clusters page, locate the target cluster.

  2. Click Edit in the Operation column.

  3. Enter the new cluster name and click OK.

Enable maintenance mode

By default, DBCC automatically performs high-availability interventions when it detects that the Coordinator node is down (it attempts to restart the Coordinator in place, and if that fails, it tries to activate the Standby node). This behavior is expected for unplanned failures but is unnecessary during planned maintenance windows (for example, when you intentionally stop the database using gpstop).

When maintenance mode is enabled, DBCC suspends all automatic high-availability actions for the cluster. This means it will not attempt to restart the Coordinator or activate the Standby node, allowing you to perform planned operations such as stopping the database, upgrading software, or performing system maintenance without interference.

To enable maintenance mode:

  1. On the Clusters page, locate the target cluster.

  2. Click Edit in the Operation column.

  3. In the Edit Cluster dialog, turn on the Maintenance Mode toggle.

  4. Click OK to confirm.

The cluster status on the Clusters page changes from HEALTHY to MAINTENANCE.

Note

Remember to disable maintenance mode after your planned maintenance is complete. To do so, repeat the steps above and turn off the Maintenance Mode toggle, so that DBCC resumes automatic high-availability protection for the cluster.

Delete cluster

  1. On the Clusters page, locate the target cluster.

  2. Click Delete in the Operation column.

  3. Confirm the deletion in the pop-up window.
