Auto-reaction alert (email) status stays as ACTION_REQUIRED

Hi experts,

I've setup monitoring on CCMS, and for errors occuring in Integration Engine (e.g. Mapping Errors), I 've configured alerts and auto-reaction methods for each of them.

I'm using the default CCMS_OnAlert_Email.

In Control Tab -> Execute Method -> The option Periodically in background process (as job) is selected.

However, when I manage to trigger an alert in CCMS, the status of the alert stays as ACTION_REQUIRED.

I have to manually trigger the auto-reaction node by selecting Edit -> Nodes (MTE) -> Start methods -> Start auto-reaction method, and then the emails will be sent out.

How can this be automated?

Please help.

Thanks.

Ron
