MQPUT and MQPUT1

 

If MQOO_BIND_NOT_FIXED is specified on an MQOPEN call, each subsequent MQPUT call invokes the workload management routine to determine which queue manager to send the message to. The destination and route to be taken are selected on a message-by-message basis. The destination and route might change after the message has been put if conditions in the network change. The MQPUT1 call always operates as though MQOO_BIND_NOT_FIXED were in effect, that is, it always invokes the workload management routine.

When the workload management routine has selected a queue manager, the local queue manager completes the put operation. If the target queue manager is a member of the same cluster as the local queue manager, the local queue manager puts the message on the cluster transmission queue, SYSTEM.CLUSTER.TRANSMIT.QUEUE, for transmission to the destination. If the target queue manager is outside the cluster, and the local queue manager has a transmission queue with the same name as the target queue manager, it puts the message on that transmission queue.

If MQOO_BIND_ON_OPEN is specified on the MQOPEN call, MQPUT calls do not invoke the workload management routine because the destination and route have already been selected.
