Error description

  • Messages sent by a z/OS queue manager in CCSID 1147 contains
    the EBCDIC New Line character x'15'. When an MQGET is attempted
    on that message with convert option on a windows queue manager
    in CCSID 819, the conversion of the New Line character is
    different between MQ V7.0.1 and V7.1 / V7.5.
    
    Following table summarizes the behavior seen
    
    NL char         MQ 7.0.1         MQ 7.1 / 7.5
    EBCDIC          ASCII            ASCII
    converted to     converted to
    x'15'           x'85             x'0A'
    
    On the server queue manager on Windows, ConvEBCDICNewline=TABLE
    is used.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of MQ version 7.1 and 7.5 setting the value
    ConvEBCDICNewline=TABLE
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM SUMMARY:
    The newline character was not being converted according to the
    conversion tables although the value of ConvEBCDICNewline was
    set to TABLE on the windows queue manager. This was causing the
    new line character to be converted into a different ASCII value
    on 7.1/7.5.
    

Problem conclusion

  • In the WebSphere MQ code the value of the attribute
    ConvEBCDICNewline was not read properly due to which the code
    was traversing a different path and hence the conversion was
    not taking place correctly.
    
    The fix ensures that the value of the attribute is read properly
    and the conversion of the newline character happens according to
    the values in the conversion tables.
