Using IXLUSYNC to Coordinate Processing of Events

User synchronization points are used to provide synchronization of processing among connectors to a structure. The IXLUSYNC service and the User Sync Point Event work together to synchronize processing.

IXLUSYNC allows connections

To define a value for a synchronization point associated with a specific event (REQUEST=SET).
To confirm that a connection has reached a synchronization point (REQUEST=CONFIRM).
To confirm the completion of the current event and define a synchronization point for the next event (REQUEST=CONFIRMSET).

The User Sync Point event is presented to connectors when a new synchronization point is set successfully and when all connectors confirm that a synchronization point has been reached. The User Sync Point event does not require an event exit response.
