Event recovery
The adapter supports event recovery for inbound processing in case of abrupt termination. During event processing, the adapter persists the event state in an event persistence table located on the data source. You must set up this data source before you can create the event persistence table.
To use the recovery feature provided in IBM BPM, you must set the value of the AssuredOnceDelivery property in the activation specification as True. If it is set to False, the failed events cannot be recovered. Duplicate events can be delivered if the AssuredOnceDelivery property is set to False. To improve performance, you can set the AssuredOnceDelivery property to False.
