Triggering in the client environment
Triggering is explained in detail in the WebSphere MQ Application Programming Guide.
Messages sent by WebSphere MQ applications running on WebSphere MQ clients contribute to triggering in exactly the same way as any other messages, and they can be used to trigger programs on the server. The trigger monitor and the application to be started must be on the same system.
The default characteristics of the triggered queue are the same as those in the server environment. In particular, if no MQPMO syncpoint control options are specified in a client application putting messages to a triggered queue that is local to a z/OS queue manager, the messages are put within a unit of work. If the triggering condition is then met, the trigger message is put on the initiation queue within the same unit of work and cannot be retrieved by the trigger monitor until the unit of work ends. The process that is to be triggered is not started until the unit of work ends.
