Suppose that you want to monitor when locks that occur on data-dictionary tables prevent you from logging on to Teradata system PROD1. You create an alert action that is based on an expired logon-timeout period using a canary query. Each time the query runs, it attempts to log in to PROD1 and then executes a simple SQL statement. If the logon fails, it times out and emails an alert to dba@example.com and logs the alert in the Alert Viewer portlet.
  1. In the Alert Setup portlet, configure delivery settings.
    1. From the Setup Options list, click Delivery Settings.
    2. From the Delivery Types list, click Email.
    3. In the SMTP Host box, type smtp.example.com as the SMTP host address of the outgoing (SMTP) email server.
    4. Select the Enable check box.
    5. From the Port list, select Use default port to use the default port 25.
    6. Enter a default Server Timeout of 30 seconds.
    7. In the Reply-To box, type doNotReply@example.com.
    8. Keep the default Anonymous login.
    9. Leave the Advanced box blank.
    10. In the Test Recipient box, type dba@example.com.
    11. Click Test to verify that the SMTP server delivers the email to dba@example.com.
    12. Click Apply.
  2. In the Alert Setup portlet, create an Action Set.
    1. From the Setup Options list, click Alert Presets.
    2. From the Preset Options list, click Action Sets.
    3. Click next to Action Sets.
    4. In Action Set Name, type Email dba.
    5. Under Actions, ensure the Include in Alert Viewer check box is selected. This option is selected by default so you can view alerts for this action set in the Alert Viewer portlet.
    6. From the Actions list, select Email recipients.
    7. Select the Email recipients check box, click Bcc or To , and in the Email box, type dba@example.com.

    10. In the Time out the login attempt after box, type 20. This is a timeout period for the logon.
    11. Leave the other default values unchanged.
    12. Click Apply.
