Changes Impacting WDA System Application Service

There has been a change made for release 5.0.11 of AVEVA NET Gatekeeper and AVEVA Change Manager that might break WDA System Application service work.

Before the change, the private component WDA.EventLogListeners.SmtpHandler.01 was used by the SMTP Event Log listener to send error notifications registered with the Operating System Event Log to the Administrator via e-mail. The component has been upgraded to support Transport Layer Security (TLS) protocol along with SMTP during sending e-mail notifications to make this process more secure. To support the change, the WDA System Application service has been upgraded as well.

If you have upgraded the 5.0.10 or earlier version of AVEVA NET Gatekeeper and AVEVA Change Manager to the 5.0.11 or later, modify the configuration file of the WDA System Application service named (by default) TIM.WDA.SystemApplication.config.xml, as follows:

1. Take a backup of the file.

2. Open the file.

3. Navigate to the <EventLogMonitor .../> section.

4. Find SMTP listeners that use the component WDA.EventLogListeners.SmtpHandler.01 as a handler and replace it with WDA.EventLogListeners.SmtpHandler.02.

5. Save the file.

Restart the WDA System Application service and ensure that it is running.
