Hi all,
How do we know whether a published document is subscribed by the intended recipient?
And what are the acknowledgement options available in wM Broker that notifies the publisher about the document subscribed status?
Please clarify, thanks.
The idea of publish subscribe is to decouple sender and receiver, so sender should not know and usually does not about the subscribers. If you need to check this from an administration perspective, the broker admin console in MWS can list all subscribers to specific document types.
Acknowledgement is not for information of the sender as well. It just tells the broker to release the transferred document from the receivers queue. This is especially used for guaranteed delivery. Details to be found in the Broker_Messaging_Programmers_Guide.
