    ****************************************************************
    * RECOMMENDATION: Apply corrective PTF when available          *
    ****************************************************************
    After applying the PTF for PM79448 (UK92381), UNLOAD DELIMITED
    of an EBCDIC table containing DBCS and/or MBCS data and using
    the default delimiters, correctly ends with RC8 after issuing
    DSNU1141I - INVALID DELIMITER CHARACTER ',' (X'6B') for an
    invalid column delimiter.
    
    PM79448 corrected a code error so that invalid delimiters, even
    if a default value, would cause the UNLOAD to fail which would
    match what was documented in the Utilities Guide and Reference.
    However, this caused a change of behavior which affected some
    customers for which the UNLOAD was working.
    
    The same error would be expected if the column delimiter was
    valid but the default character delimiter '"' (x'7F') was used.
    
    As they are default delimiters, UNLOAD should allow them to be
    used successfully.
    
    This same outcome would occur in DB2 9 with PM79448 (UK92382)
    applied and in DB2 11.
    

Problem conclusion

  • The fix for PM79448 has been removed and UNLOAD DELIMITED code
    has been changed to allow the default value for the column
    delimiter (x'6B') and for the character delimiter (X'7F') when
    unloading from an EBCDIC table containing MBCS and/or DBCS
    columns and defaulting to the encoding scheme of the table for
    the output.
    
    
    As such, the following document changes will be made to the
    Utility Guide and Reference.
    
    A. DB2 9 for z/OS
    
    1. Under the chapter for LOAD, Table 36. Maximum delimiter
       values for different encoding schemes:
    
      Encoding scheme       Maximum allowable value
      EBCDIC SBCS           None
    | EBCDIC DBCS/MBCS      X'3F' (X'7F', X'4B', X'6B' also allowed)
      ASCII/Unicode SBCS    None
      ASCII/Unicode MBCS    X'7F'
    
    2. Under the chapter for UNLOAD, Table 125. Maximum delimiter
       values for different encoding schemes:
    
      Encoding scheme       Maximum allowable value
      EBCDIC SBCS           None
    | EBCDIC DBCS/MBCS      X'3F' (X'7F', X'4B', X'6B' also allowed)
      ASCII/Unicode SBCS    None
      ASCII/Unicode MBCS    X'7F'
    
    
    B. DB2 10 for z/OS
    
    1. Under the chapter for LOAD, Table 37. Maximum delimiter
       values for different encoding schemes:
    
      Encoding scheme       Maximum allowable value
      EBCDIC SBCS           None
    | EBCDIC DBCS/MBCS      X'3F' (X'7F', X'4B', X'6B' also allowed)
      ASCII/Unicode SBCS    None
      ASCII/Unicode MBCS    X'7F'
    
    2. Under the chapter for UNLOAD, Table 127. Maximum delimiter
       values for different encoding schemes:
    
      Encoding scheme       Maximum allowable value
      EBCDIC SBCS           None
    | EBCDIC DBCS/MBCS      X'3F' (X'7F', X'4B', X'6B' also allowed)
      ASCII/Unicode SBCS    None
      ASCII/Unicode MBCS    X'7F'
    
    
    C. DB2 11 for z/OS
    
    1. Under the chapter for LOAD, Table 36. Maximum delimiter
       values for different encoding schemes:
    
      Encoding scheme       Maximum allowable value
      EBCDIC SBCS           None
    | EBCDIC DBCS/MBCS      X'3F' (X'7F', X'4B', X'6B' also allowed)
      ASCII/Unicode SBCS    None
      ASCII/Unicode MBCS    X'7F'
    
    2. Under the chapter for UNLOAD, Table 125. Maximum delimiter
       values for different encoding schemes:
    
      Encoding scheme       Maximum allowable value
      EBCDIC SBCS           None
    | EBCDIC DBCS/MBCS      X'3F' (X'7F', X'4B', X'6B' also allowed)
      ASCII/Unicode SBCS    None
      ASCII/Unicode MBCS    X'7F'
