Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users querying channel status using runmqsc or PCF  to check the
    BYTSSENT and BYTSRCVD attributes
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    MQ uses a 4 byte unsigned integer to store the BYTSSENT and
    BYTSRCVD attributes and the maximum value that
    can be stored is 4294967295(0xffffffff). A defect in the MQ code
    in handling the overflow in the BYTSSENT and BYTSRCVD values
    caused MQ to display incorrect values (value lower than the
    previous recorded value).
    

Problem conclusion

  • MQ code has been modified to display 4294967295 for BYTSSENT and
    BYTSRCVD when the value exceeds 4294967295.
