Managing a Server Cluster

CDS offers easy to use management options for database clusters.

Fields on the Administrative Settings dialog display the current owner and the email address to which notification emails about the state of the cluster are sent. You can also use the dialog to modify the network security rules for the cluster.

To access the dialog, highlight the name of a cluster on the Clusters tab, and click the Administrative Settings icon.

The Administrative Settings dialog

Use the fields on the dialog to modify the Administrative settings for a cluster:

  • Use the drop-down listbox in the Owner field to select a new cluster owner; please note that only those users with permissions to access the tenant on which the cluster resides are included in the list.
  • Use the Notification Email field to specify the address to which you wish notices about the state of the cluster to be sent.
  • Use the Add Rule button to open a popup that allows you to define a new security rule for the cluster.
  • Highlight a security rule and click the Delete Rule button to delete a security rule for the cluster.

After modifying the administrative settings for the cluster, click the Confirm button to preserve your changes.

Managing Database Server Operations

Highlight a cluster name and select the Restart/Reload DB Servers icon (located in the left column on the Clusters tab) to initiate a database restart or reload operation on one or more cluster nodes.

  • Check the box next to a host address to restart or reload the selected server.
  • Select a radio button next to Restart or Reload to specify the action that will be performed.

After making your selections, click Confirm to start the restart or reload operation. A popup will confirm that the server(s) are restarting or reloading. You can confirm the status of the operation in the cluster’s Events table.
