PK74159: SAXPARSEEXCEPTION CONVERTING DBCS SHIFT STATE DATA ACROSS SEGMENT BOUNDARIES

Obtain the fix for this APAR.

APAR status

• Closed as unreproducible.

Error description

• The CONVERT_DATA function in DFHCCNVG, used for container CCSID
  conversion, does not preserve DBCS shift information between
  segments of a multi-segment message when z/OS conversion is used
  (for example when the other CCSID is UTF-8). This means the
  conversion will generate incorrect output if either the input or
  output is in DBCS shift across a segment boundary.

  ****************************************************************
  The subcodepage value returned from z/OS Conversion Services for
  the conversion of the last character in a message segment was
  not saved so that when z/OS Conversion Services was called to
  convert the next segment of the message it always used a
  subcodepage value of zero. If the last character in the first
  segment was MBCS the shift state was lost and the subsequent
  characters in the next segment were converted as SBCS.
  

Problem conclusion

Temporary fix

• FIX AVAILABLE BY PTF ONLY
  

Comments

• DFHCCNVG has been amended to preserve the DBCS shift state
  across segment boundaries during z/OS conversion by saving the
  subcodepage value of the last character in the segment
  returned from z/OS Conversion Services and then setting the
  same subcodepage value on the call to z/OS Conversion
  Services to convert the subsequent segment.
