IC68194: EVENT SEQUENCING DOES NOT DISABLE REDELIVERY OF FAILED MESSAGES

WebSphere Enterprise Service Bus V7.0.0 Fix Pack 3 (7.0.0.3)
WebSphere Enterprise Service Bus V7.0.0 Fix Pack 4 (7.0.0.4)

APAR status

• Closed as program error.

Error description

• Generated Activation Specs for MQ and MQ/JMS exports do not
  disable redelivery of failed messages when Event Sequencing is
  enabled in the binding.  Since MQ does not preserve message
  order with redelivery of failed messages this causes messages
  order to be broken.

Problem summary

• ****************************************************************
  * USERS AFFECTED: Customers using WebSphere Enterprise         *
  *                 Service Bus and WebSphere Process Server     *
  *                 v7.0 to generate Activation Specs for MQ     *
  *                 and MQ/JMS exports may find that             *
  *                 redelivery of failed messages is not         *
  *                 disabled.                                    *
  ****************************************************************
  * PROBLEM DESCRIPTION: By default, when the Activation Spec    *
  *                      for MQ and MQ/JMS exports is created,   *
  *                      the setting "disable Failed Message     *
  *                      Redelivery" is set to false. This       *
  *                      means that redelivery will be           *
  *                      attempted, causing the message order    *
  *                      held in MQ to be broken.                *
  ****************************************************************
  * RECOMMENDATION: If you require message order to be           *
  *                 preserved when using MQ or MQ/JMS exports    *
  *                 then you are advised to install the fix      *
  *                 pack which contains the code update          *
  *                 associated with this APAR.                   *
  ****************************************************************
  Generated Activation Specs for MQ and MQ/JMS exports do not
  disable redelivery of failed messages when Event Sequencing is
  enabled in the binding.  Since MQ does not preserve message
  order with redelivery of failed messages this causes messages
  order to be broken.
  
  The change in this APAR will mean that when creating the
  Activation Spec when Event Sequencing is enabled the setting
  "disable Failed Message Redelivery" will be set to true.
  
  
  The behaviour will then be that the listener will stop and the
  message will be rolled back to the queue on first failure.
  

Problem conclusion

• The code has been modified so that the listener will stop and
  the message will be rolled back to the queue on first failure.
  
  This code fix was targeted to be included in the following fix
