IT16168: .NET sample application simplexaget fails and generates an FDC with probe ID AT040010 in component atxClose

APAR status

• Closed as program error.

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.
