Data for Inter-Process Communication

The Notify Configuration shared configuration resource defines the data that the Notify activity passes to the corresponding Wait activity or Receive Notification process starter. The schema for the data is defined in the same way as any other schema is defined. See Editor for more information on specifying schemas.

The same Notify Configuration resource is used to configure the Notify activity as well as the Wait activity and the Receive Notification process starter. The schema in the Notify activity’s configuration appears in the Notify activity’s input schema. This allows you to map process variables to the Notify activity’s input. The Notify activity then passes its data to its corresponding Wait or Receive Notification.

The Wait activity and Receive Notification process starter have output that matches the Notify Configuration specified on their Configuration tab. This allows you to use the data passed by the process with the Notify activity in subsequent activities after the Receive Notification or Wait activities.

If you wish only to signal the waiting process to continue but not exchange data, the Notify Configuration schema used by the Notify/Receive Notification/Wait activities can be empty. However, the same Notify Configuration resource must be specified by corresponding Notify and Receive Notification or Wait activities. Only activities with the same Notify Configuration resource can communicate with each other.
