APAR status

  • Closed as program error.

Error description

  • When using the MQ Explorer to display the channel status for
    connected MQTT clients, the value
    for the "Protocol" attribute shows up as "[Unknown]" instead of
    the actual protocol level.
    

Local fix

  • Using runmqsc command:
    [DISPLAY CHSTATUS(*) CHLTYPE(MQTT) CLIENTID(*) ALL]
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users of the MQ Explorer displaying the
    channel status of connected MQTT clients.
    
    
    Platforms affected:
    Windows, Linux on x86-64, AIX
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    When using the MQ Explorer to display the channel status of
    currently connected MQTT clients, the "Protocol" value for these
    clients was displayed as "[Unknown]" instead of the actual
    protocol value, for any non-HTTP clients using the MQTT 3.1.1
    protocol. The channel status of clients connected using the MQTT
    v3 protocol, or using HTTP/JavaScript MQTT clients displayed
    their protocol values correctly.
    

Problem conclusion

  • The MQ Explorer's channel status display for connected MQTT
    clients now shows the correct protocol value for each client.
