About this task

Note:
  • The Acknowledgment mode must be set to Client acknowledge to retry messages when processing fails.
  • For concurrent processing, setting the Acknowledgment mode to Auto acknowledge improves the processing performance if message recovery is not a concern.

Procedure

  1. From Events > Messaging, click the subscriber.
    The Subscriber details page is displayed.
  2. Click the Subscriber settings icon.
    The Subscriber settings dialog is displayed.
  3. Set Acknowledgment mode with one of the following values:
    • Client acknowledge - Acknowledges a message only after the invocation finishes.
    • Auto acknowledge - Acknowledges the message automatically after the subscriber receives the message. The subscriber does not wait until the processing is completed. If the flow service execution fails or if the workflow invocation fails, The subscriber cannot recover the message.
