Description

Use the IXLUSYNC macro to synchronize the processing of user-defined events for multiple connectors to a given structure. IXLUSYNC allows users to establish “sync points” to indicate that all active connectors to a structure have confirmed that processing for an event is complete. Connectors are notified when a sync point is reached by means of the User Sync Point event being presented to their event exit.

You can use IXLUSYNC:

To define a value to be associated with a user-defined event, the processing for which is to be synchronized among all active connectors.
To confirm that the processing related to an event has been completed. When all active connectors have confirmed the event, the sync point is reached.
To confirm that the processing associated with an event has completed and then to set a new event for which processing is to be synchronized.

You can also use IXLUSYNC to provide a response on behalf of a peer connector that has disconnected or failed prior to responding to a user-defined event.

Only one user-defined event can be set at a time for the active connectors to a structure.
