Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users sending messages larger than 1MB from an MQ version 7.x
    queue manager to an MQ version 8 queue manager over a message
    channel with both SSL/TLS security and message data compression
    enabled.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    This problem occurred because the MQ v8 queue manager did not
    correctly calculate the maximum message segment size when
    communicating with pre-version 8 clients using SSL/TLS security.
    

Problem conclusion

  • MQ has been modified to correctly calculate the maximum message
    segment size.
