### Administering clustered servers

To administer clustered server, on the JReport Administration page, click Cluster on the system toolbar, then,

- To shut down all servers or just one server:
  1. Click the Admin tab, from the Shut Down Server drop-down list, select the server you want to shut down (or select All).
  2. Click the Shut Down button.

- To set whether to notify somebody via e-mail when a server is down:

  1. In the Admin tab, check the Enable notification after a server has been shut down option if you want the cluster to send a notification mail to the specified e-mail address.
  2. Enter the e-mail address in the E-mail Address box.
  3. Click OK to save the settings.

  Note: This option only applies to JReport Enterprise Server cluster environment, since at least one running server is required for sending the e-mail when the other servers are down.
