Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users with JMS clients at base level (7.0.0.0) may be impacted
    by this problem.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    An issue with the base level JMS client (7.0.0.0) means that it
    may request a further conversation when conversations are
    configured to be 1. The SVRCONN channel fails to detect that.
    

Problem conclusion

  • Added check in the WebSphere MQ code for exceeding the
    configured max conversations setting, reporting that as a
    protocol error FDC.
