Error description

    withdrawn from the product
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All MQ users using channels for communication.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    APAR IV56612 introduced code changes which check the TRPTYPE of
    the channel on both communicating sides. For example, both the
    sender and receiver sides of the channel pair.
    
    The channels would not be started if the TRPTYPE on each side
    did not match.
    
    This change was directly in contradiction with the documented
    behaviour of MQ, which states the following for the TRPTYPE
    attribute:
    
    "This parameter is optional because, if you do not enter a
    value, the value specified in the SYSTEM.DEF.channel-type
    definition is used. However, no check is made that the correct
    transport type has been specified if the channel is initiated
    from the other end. On z/OS, if the SYSTEM.DEF.channel-type
    definition does not exist, the default is LU62."
    

Problem conclusion

  • The IV56612 code changes have been removed from the product in
    order to remain consistent with the documented behavior.
    Accordingly, this check of the TRPTYPE values is no longer
    performed.
