The adapter creates the event store or event table on the enterprise information system (EIS) during deployment to the server. Each time a file is created, updated, or deleted, the adapter tracks this as an event. The status of events is continually updated by the adapter for recovery purposes until they are delivered to a configured endpoint on the application server.
During inbound processing, the adapter polls event files from the event directory at regular intervals. Before posting each event to the endpoint, the adapter creates an entry for the event in the event store and keeps track of it by updating the status of the entry as it moves through the system. If an event is successfully posted, event store entries are deleted. For failed events, the entries remain in the event table. Optionally, the adapter can archive successfully polled event files in a user specified archive directory. The event directory, archive directory, poll interval, and poll quantity (the number of event files to poll in a single poll cycle) are all configurable parameters.
The status of each event is stored for recovery purposes. The figure below illustrates the event management framework.
