Outbound Notification Mailer Processing

When the Workflow Engine determines that a notification message must be sent, it raises an event in the Business Event System called oracle.apps.wf.notification.send. Oracle Workflow provides a seeded subscription to this event, which is defined to be deferred immediately so that the workflow process that owns the notification can continue. The event is placed on the standard WF_DEFERRED agent. Oracle Workflow provides a seeded agent listener named Workflow Deferred Notification Agent Listener that runs on this agent to continue notification processing. This agent listener is dedicated solely to processing deferred notification events.

When the event is dequeued from WF_DEFERRED and the subscription is processed, the subscription requires the event data for the event, causing the generate function for the event to be executed. The generate function for this event performs the following actions:

Finally, the subscription places the event message on the standard WF_NOTIFICATION_OUT agent.

A notification mailer service component polls the WF_NOTIFICATION_OUT agent for messages that must be sent by e-mail. When the notification mailer dequeues a message from this agent, it uses a Java-based notification formatter to convert the XML representation of the notification into a MIME (Multi-purpose Internet Mail Extensions) encoded message and sends the message by the Simple Mail Transfer Protocol (SMTP).

The e-mail notifications are based on message templates defined in Oracle Workflow Builder. Oracle Workflow provides a set of standard templates in the System: Mailer item type, which are used by default. It is not recommended to modify the standard templates. However, you can customize the message templates used to send your e-mail notifications by creating your own custom message templates in the System: Mailer item type using the Workflow Builder, and assigning these templates to a particular notification mailer service component in the mailer configuration parameters. The templates assigned to a mailer override the default System: Mailer templates. See: Modifying Your Message Templates.

Additionally, you can create your own custom message templates in a custom item type using the Workflow Builder, and assign these templates to a particular notification in a workflow process by defining special message attributes. In this case the templates assigned to the notification override both the templates assigned to a mailer and the default System: Mailer templates. See: Modifying Your Message Templates and Notification Mailer Message Template Attributes, Oracle Workflow Developer's Guide.
