- Note:
- These recovery steps do not apply if a disk failure occurs or
if a disk is full.
To recover from failures during event notification, the
connector:
- The connector processes IDocs from the JMS-MQ message in the
event queue (specified in the SAPALE_Event_Queue
configuration property). When it successfully processes a IDoc, the
connector logs an entry in the EventState.log file.
- If none of the work units in the event message fails
processing, the connector moves the event message to the archive
queue with an IDocProcessStatus value of success.
- If any of the work units in the event queue message fails
processing, the connector will move the event message to the
archive queue and update the IDocProcessStatus value of
partial.
- After the connector processes all IDocs in an event message, it
clears the EventState.log file and begins writing
entries to it for the next event message.
- If the connector goes down before it processes all IDocs in an
event message, it uses the information in
EventState.log to determine where to begin
processing during the recovery process. When it comes back up, the
connector checks whether there are any entries in the log file.
If the connector has created only the header portion of the
message in the WIP queue but not the data portion, this procedure
will recover the data portion of the message.
- Examine the SAP connector log for error messages pertaining to
the business object's name, message type, or verb.
- Make the appropriate corrections to the business object
definition or the connector configuration.
- Note:
- Configuration changes may include changes to MQSeries queues.
For more information, see Prerequisites to running
the ALE Module..
- Restart the connector.
