So.. Simply leave out the value in the RQMNAME for the definition.

So this doc:
http://www.ibm.com/developerworks/websphere/library/techarticles/1108_gupta/1108_gupta.html?ca=drs-

is wrong for:

Remote Queue Definition of Cluster Queue

DEFINE QREMOTE (IBM.ESB.IN) RNAME (IBM.ESB.IN) RQMNAME (IBMESBQM1)
DEFINE QALIAS (INPUT) TARGQ (IBM.ESB.IN)


I know its not magic, so the QMGR for where to put the message on must be populated by the Gateway QMGR based on the clustering algorithm?


It's not wrong... it just doesn't load-balance between the two brokers in that scenario.

The flow there uses JMS, so it is always reading messages from one queue manager - regardless of which broker is running the flow. JMSInput node can read from remote qmgrs - MQInput can't.

So that qremote is designed to always send messages to one queue on one queue manager, and not designed to load-balance messages across two instances in the cluster.
