Question & Answer


Question

You notice that a message flow in IBM Information Bus (IIB) or IBM Application Connect Enterprise (ACE) sent a message to the Dead Letter Queue (DLQ) of the IBM MQ queue manager.
The reason code for this message is: 
    Hexadecimal 0x00010000  = decimal 65536

… but you could not find this reason code in the online MQ manual
