About the MQPMO_SYNCPOINT Option

The EAI MQ Series Server Transport business service uses the MQPMO_SYNCPOINT option for sending messages to IBM WebSphere MQ using the IBM MQ API.

MQPMO_SYNCPOINT sends the message with syncpoint control. A syncpoint is a logical point in the execution of a program where changes made by the program can be saved. The message request operates within the unit of work: the message is not visible outside the unit of work until the unit of work is saved. If the unit of work is rolled backed, then the message is deleted. For more information on syncpoint options, consult the IBM WebSphere MQ documentation at:
