PUBACKINT

The number of messages published by a publisher before IBM MQ classes for JMS requests an acknowledgment from the broker.

When you lower the value of this property, IBM MQ classes for JMS requests acknowledgments more often, therefore the performance of the publisher decreases. When you raise the value, IBM MQ classes for JMS take a longer time to throw an exception if the broker fails. This property is relevant only if TRANSPORT has the value BIND or CLIENT.
