Error description

  • When MQ Light applications create a durable subscription (for
    example by setting the MQ Light destination-ttl attribute), all
    messages published by other MQ Light applications to that
    subscriber become persistent MQ messages, even if the DEFPSIST
    attribute of the matching MQ Topic object is set to NO.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Customers that wish to send non-persistent MQ Light messages to
    MQ Light applications that have created durable subscriptions.
    
    
    Platforms affected:
    Linux on Power, Linux on x86-64, Solaris x86-64, Solaris SPARC,
    Linux on zSeries, Linux on S390, HP-UX PA-RISC, HP-UX Itanium,
    AIX, Windows
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    The problem was caused by incorrect handling of published MQ
    Light messages by the AMQP channel.
    

Problem conclusion

  • If an AMQP or MQ Light publisher doesn't specify the persistence
    of a message by setting the AMQP 'durable' header, the AMQP
    channel now correctly uses the value of the DEFPSIST attribute
    of the matching MQ Topic object, rather than forcing all
    messages to durable subscriptions to be persistent.
    
    Note: If the AMQP publisher specifies a valid durable header in
    its message, the value of this is always honoured and the
    DEFPSIST attribute is ignored.
