Error description

  • When displaying the channel status of connected AMQP client
    instances using a command like:
    
    DISPLAY CHS(*) CHLTYPE(AMQP) CLIENTID(<clientid>) ALL
    
    the value of AMQPKA for each client channel instance
    (representing the time interval between keep alive frames sent
    from the queue manager's AMQP service to the connected client)
    always displays as 0, whatever the value of this property was
    set to initially, or negotiated to when the AMQP client
    connected.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users inquiring the time interval between
    keep alive frames sent from an IBM MQ AMQP channel to the
    connected AMQP client in the channel status output for that
    client.
    
    
    Platforms affected:
    Windows, Solaris x86-64, Solaris SPARC, Linux on x86-64, AIX,
    Linux on Power, Linux on S390, HP-UX Itanium
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    When displaying the status of IBM MQ AMQP channel instances, the
    value of the AMQPKA attribute was always shown as being 0. This
    was wrong. The AMQPKA attribute should have had a value
    representing the AMQP channel instance's AMQPKA interval, as
    negotiated on the channel.
    

Problem conclusion

  • The channel status for a AMQP channel instance now displays a
    value for AMQPKA representing the interval between keep alive
    frames sent from the AMQP channel to a connected AMQP client.
