Sun Java System Message Queue 4.3 Administration Guide

Reliability And Flow Control

Because “payload” messages sent and received by clients and control messages (such as broker acknowledgments) used by Message Queue itself pass over the same client-broker connection, excessive levels of payload traffic can interfere with the delivery of control messages. To help alleviate this problem, the connection factory attributes listed in Table 18–5 allow you to manage the relative flow of the two types of message. These attributes fall into four categories:

The use of any of these flow control techniques entails a trade-off between reliability and throughput; see Client Runtime Message Flow Adjustments for further discussion.
