APAR status

  • Closed as program error.

Error description

  • 2 system queues - SYSTEM.AMQP.TRANSMIT.QUEUE and
    SYSTEM.AMQP.PERSISTENT.STATE - are created when the AMQP service
    is started. They are not used by the AMQP service or AMQP
    channels. They have no effect on the behaviour of any queue
    manager function but they are extraneous and are not required.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users who have installed the AMQP Service
    component and started an AMQP channel.
    
    
    Platforms affected:
    AIX, HP-UX Itanium, Linux on Power, Linux on S390, Linux on
    x86-64, Linux on zSeries, Solaris x86-64, Solaris SPARC, Windows
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    When an AMQP channel was started it checked for the presence of
    3 internal system queues on the queue manager. If the queues did
    not exist the AMQP channel defined them. The queues were not
    required by the AMQP channel and their presence on the queue
    manager was not necessary for AMQP function to work correctly.
    

Problem conclusion

  • The AMQP channel no longer checks for or creates the unneeded
    system queues.
