• Overview for MQCIH
  The MQCIH structure describes the header information for a message sent to CICS across the CICS bridge. For any IBM MQ supported platform we can create and transmit a message that includes the MQCIH structure, but only an IBM MQ for z/OS queue manager can use the CICS bridge. Therefore, for the message to get to CICS 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.
