Error description

  • In IBM MQ v8.0 an application that reads from a queue can fail
    to get
    messages that are put to the queue as a group.
    
    The failure occurs for new messages put to the queue in a group
    after the application opens the queue and tries to get
    messages.
    
    If the group of messages is already on the queue
    when the application tries to read from the queue then the
    operation
    succeeds.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of grouped messages may be affected by this problem.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    A flag was not set correctly which meant that IBM MQ failed to
    identify a waiting MQGET request as being eligible for message
    delivery.
    

Problem conclusion

  • The code was changed so that the flag was set correctly. This
    caused the IBM MQ messaging logic to correctly identify a
    waiting MQGET as being eligible for message delivery.
