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 이메일 field to specify the address to which you wish notices about the state of the cluster to be sent.
Use the fields in the Configure Network 보안 Rules section to define security rules that allow access to the cluster. By default, the load balancer port is open to any IP address for client connections; you may choose to delete the rule, and specify a more restrictive IP range.
To delete a rule from the list, highlight the rule and click the Delete Rule button; you will be prompted to confirm that you wish to delete the entry before the server removes the rule.
Click the Add Rule button to open the Add Rule dialog (see Figure 5.5) and provide access to a port.

On the Add Rule dialog:
Use the Port drop-down listbox to select the port that can be accessed from the specified CIDR. A non-administrative user can allow access to ports:
9999 - for client connections and load balancing.
5432 or 5444 - the cluster specific database listener port.
An administrative user can use the Add Rule dialog to add a rule that allows SSH access to Port 22.
Use the CIDR field to specify the address (or address range) that will be allowed access to the server through the selected port.
When you're finished, click Apply to create the security rule.
After modifying the configuration details for the cluster, click the Confirm button; a dialog will open, prompting you to provide the password associated with the connected session (see Figure 5.14).

Provide a password in the Password field and click Confirm to save your changes and exit, or Cancel to exit without saving the changes.
