Poll Message activity

The Poll Message activity is a starter activity that polls the configured queue for the message. This activity supports the ATLEAST ONCE and EXACTLY ONCE delivery semantics. The Poll Message Activity supports batching, if the batching option is selected.

About this task

The EXACTLY ONCE delivery semantic is handled through the message acknowledgement. Since the JMS provider must never deliver a copy of an acknowledged message, the Poll Message activity leverages the provider for the EXACTLY_ONCE delivery semantic. When the batching option is selected, if there is more than one message in the queue, the activity processes all the messages at once, instead of processing them one at a time.
Important: This orchestration must have a JMS endpoint representing the data source, otherwise, output mapping is disabled.
