You can send messages to remote queue objects by using the msgsend remote_qmgr option to specify the names of your remote queue managers when:
The local queue manager and the remote queue manager are in a single cluster, and the local queue manager stores the cluster queue manager definition of the remote queue manager.
There is a transmit queue on local queue manager, and the name of the transmit queue is same to the remote queue manager.�
There is a queue manager alias on local queue manager, and the name of the queue manager alias is same to the remote queue manager.�
Adaptive Server sets the remote queue manager as the
target queue manager, and sets the queue as the target queue. As
soon as Adaptive Server sends a message to the related transmit
queue, it returns with successful status, even though it has not
yet sent a message to the target queue.�
