Configure JMS message flows to send a batch acknowledgment for receipt of non-transactional JMS messages.
When the JMSInput node works in non-transactional mode, receipt and acknowledgment of messages take place in one step, followed by the message processing. In some scenarios, this acknowledgment response to the JMS server for each message might create an unacceptable level of network traffic. For example, using this messaging model to receive JMS messages across a wide area network that is already handling large volumes of traffic might result in non-optimal throughput rates for JMS messages.
The JMSInput node can acknowledge message receipt in batches rather than individually for non-transactional messages. Batch acknowledgment is enabled using the JMSProviders configurable service properties clientAckBatchSize and clientAckBatchTime. You can set these properties separately, or use them together, to tune the number of messages that are received and processed by the node before an acknowledgment response is returned to the source JMS server.
To disable batch acknowledgment, set both clientAckBatchSize and clientAckBatchTime to 0.
