Error description

  • In MQ v6, if "Fmt" tag does not contain any value(empty), then
    MQ JMS adds "?format=" with no value. But in MQ v7 the queue
    manager adds only if it is non empty. This caused failure in
    selecting the message.
    
    Sample message:
    
    <mcd><Msd>xmlns</Msd><Set></Set><Type>ImportMembers</Type>
    <Fmt></Fmt></mcd>
    
    Selector:
    
    JMSType = 'mcd://xmlns//ImportMembers?format='
    
    MQ V6 derived property:
    
    JMSType = 'mcd://xmlns//ImportMembers?format='
    
    MQ v7 derived property:
    
    JMSType = 'mcd://xmlns//ImportMembers'

    PROBLEM SUMMARY:
    In MQ v6, if "Fmt" tag does not contain any value(empty), then
    MQ JMS adds "?format=" with no value. But in MQ v7 the queue
    manager adds only if it is non empty. This caused failure in
    selecting the message.
    
    Sample message:
    
    <mcd><Msd>xmlns</Msd><Set></Set><Type>ImportMembers</Type>
    <Fmt></Fmt></mcd>
    
    Selector:
    
    JMSType = 'mcd://xmlns//ImportMembers?format='
    
    MQ V6 derived property:
    
    JMSType = 'mcd://xmlns//ImportMembers?format='
    
    MQ v7 derived property:
    
    JMSType = 'mcd://xmlns//ImportMembers'
    

Problem conclusion

  • The queue manager selector matching code has been modified to
    accommodate empty/blank attribute values. This feature is
    available only if the AMQ_SUPPORT_EMPTY_JMSTYPE_PROP
    environment variable is set.
    
    To enable the queue manager to support empty Fmt property,
    export AMQ_SUPPORT_EMPTY_JMSTYPE_PROP to a non null value and
    then restart the queue manager.
    
    Example:
    
    * Stop the applications, queue manager and the listener
    * export AMQ_SUPPORT_EMPTY_JMSTYPE_PROP=1
    * Restart the queue manager, listener and the applications
    
    Note: The new v7 feature and the old v6 feature will not
    available together.
