• Overview for MQWIH
  The MQWIH structure describes the header information for a message sent to z/OS workload management (WLM). For any IBM MQ supported platform we can create and transmit a message that includes the MQWIH structure, but only an IBM MQ for z/OS queue manager can interact with WLM. Therefore, for the message to get to WLM from a non-z/OS queue manager, your queue manager network must include at least one z/OS queue manager through which the message can be routed.
