Error description

  • The CreateDate (PCF id MQCA_CREATION_DATE) within a Queue
    Statistics message has incorrect contents.
    
    It should be of the form 'yyyy-mm-ddbb', where the last two
    bytes 'b' are blanks, but it has the contents 'yyyy-mm-gggg'
    where 'gggg' is some non-blank data corresponding to the first 4
    bytes of the CreateTime.
    
    Therefore the portion of the CreateDate that might be expected
    to hold the day of the month (dd) in fact holds the hour of the
    day.  This will usually result in the dd value being wrong.
    
    See the example below:
    
    String (MQCFST)
    Parameter Id : 2004 (MQCA_CREATION_DATE)
    Value : "2016-10-21.5  "
    String (MQCFST)
    Parameter Id : 2004 (MQCA_CREATION_TIME)
    Value : "21.53.56"
    
    This problem was introduced as a side-effect in MQ 8.0.0.5 via
    APAR IT12103.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of MQ 8.0.0.5 who are using the Queue Statistics PCF
    messages and are relying on correct formats appearing for the
    CreateDate portion of the message.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    After the change in IT12103, the CreateDate (12 bytes long) was
    copied wrongly from a data area that was 8 bytes long, so was
    smaller than the 12 bytes needed.
    
    Therefore the resulting CreateDate in the PCF message contained
    the first 8 bytes of the true creation date, and the first 4
    bytes of the creation time, which was held in the next portion
    of memory.
    
    No unsafe memory operations took place, but the resulting data
    was incorrect.
    

Problem conclusion

  • The MQ code has been corrected to ensure a 12 byte data area is
    used to hold the creation date before copying to the PCF
    message.  This ensures the value copied to the PCF message will
    be valid.
