Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    WMQ users utilizing Distribution lists connecting to V7.1.0.x
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    WMQ code was incorrectly assuming that PutMsgRecFields in the
    MQDH header was non-zero which resulted in an invalid
    MQRC_DH_ERROR. The PutMsgRecFields field is an optional field
    with an initial value of zero.
    

Problem conclusion

  • WMQ code has been modified to appropriately account for a zero
    PutMsgRecFields field in the MQDH header.
