WebSphere Adapter for FTP

Event store

Files created by the FTP server or any third party application in the event directory of the FTP server are called event files. Each business object record present in the event file is called an event. The adapter creates an entry in the database table, called an event store, to track each of these business object records until the event is posted to the endpoint.

If the database server goes down during an inbound operation, the adapter will send an exception. The database server and the adapter must be restarted to process the events.

Event table structure

Column Name Type Description
EVNTID Varchar(255) Each event requires a unique event ID for tracking purposes. The adapter uses this ID to track events during inbound operations.
EVNTSTAT integer The status of the event. The adapter uses the status to determine whether an event is new or in process.
Event status values:
NEWEVENT (0)
The event is ready to be processed.
PROCESSED (1)
The adapter successfully processed and delivered the event.
FAILED (-1)
The adapter was unable to process this event due to one or more problems.
XID Varchar(255) Used by the adapter for assured event delivery and recovery.
EVNTDATA Varchar(255) Used by the adapter to mark the failed events as ARCHIVED to ensure that they are not processed again during adapter startup or recovery.
