Safety of messages

IBM MQ distributed queue management ensures that messages are delivered properly. This is still the case when MQIPT is present between the two ends of the channel. MQIPT does not store any message data or participate in the sync point procedure that ensures correct message delivery.

When using fast, non-persistent IBM MQ messages, if the MQIPT route fails or is restarted when an IBM MQ message is in transit, the message might be lost. Before restarting the route, make sure that all IBM MQ channels using the MQIPT route are inactive.
