Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of MQRFH2 Publish/Subscribe.  This protocol is superseded
    by newer MQ V7 Publish/Subscribe APIs.  Typically this protocol
    was only used by WebSphere Message Broker in releases 6 and
    earlier.  But it is also possible for some user applications to
    be developed to use the same protocol.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    The WebSphere MQ Publish/Subscribe product code was parsing the
    MQRFH2 DeregSub command and was incorrectly rejecting the
    command when it contained a value for SubUserData.
    

Problem conclusion

  • The WebSphere MQ Publish/Subscribe product code has been
    corrected so that, when parsing the MQRFH2 DeregSub command, it
    accepts the command when it contains a value for SubUserData.
    The value is accepted but is ignored, because it is not needed
    for the operation of the deregister command.
