Oracle Workflow executes subscriptions to this event when an event is raised locally or received from an external source, but no subscription exists on that event.

Attention: You must not change or disable the definition of the Unexpected event. If you do, the Event Manager will not be able to perform error handling for event and subscription processing.

Oracle Workflow provides two default subscriptions to the Unexpected event. The first subscription sends the event message to the Default Event Error process in the System: Error item type when an unexpected event is received from an external source. This subscription allows your local system to handle any event messages received from external systems that you were not expecting.

The Default Event Error process notifies the system administrator, who can retry or abort subscription processing for the event. For example, the system administrator can optionally define a subscription to process the event and then retry the event.

The External subscription to the Unexpected event is enabled by default. You can disable it if necessary.

Attention: If you want to disable this subscription, be careful to consider all the consequences for handling unexpected event messages from external sources. If the subscription is disabled, these event messages will remain on the inbound queue where they are received and may be undetected for some time.

The following table lists the properties defined for this subscription.

The second subscription sends the event message to the Default Event Error process in the System: Error item type when an unexpected event is received from an Error source (that is, when it is dequeued from the WF_ERROR queue). This subscription is enabled by default.

Attention: You must not change or disable the definition of the predefined Error subscription to the Unexpected event. If you disable this subscription, then the Event Manager will not be able to perform error handling for any events for which you have not defined custom Error subscriptions.

The following table lists the properties defined for this subscription.
