Error description

  • The amqrfdm command which dumps the IBM MQ queue manager's
    cluster cache shows invalid date and time values for the "Exp"
    or "Upd" attributes for a cluster object.
    
    Example:
    
     Exp(rfdPrintTime: csTx buffer too small) Raw(x5E32FDFB)

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    User using amqrfdm service tool in an environment having
    modified LANG/locale settings may come across this problem.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    When executing the amqrfdm utility with a modified LANG/locale
    setting, it was possible that the formatted time string was too
    large for the available buffer, resulting in the message above
    being printed instead.
    
    The problem is caused when OS calls strftime() used for
    formatting date time returns more characters than the allocated
    buffer can hold. This can occur when the locale settings are
    modified to a specific language like  ko_KR.UTF-8.
    

Problem conclusion

  • The OS time formatting call returning bigger length for a
    specific LANG/locale settings was causing the issue. The code
    was changed to accommodate a formatted string of greater length.
    
    In cases where the formatted string remains too large for the
    available buffer, the timestamp will be printed as an epoch time
    value.
