JR58664: PARALLEL ENGINE SORT STAGE ON WINDOWS CAN CREATE BAD SORATCH FILE NAMES WHEN USING MULTIBYTE CHARSETS.

APAR status

• Closed as program error.

Error description

• The PX Tsort operator creates and deletes scratch files at
  runtime. It generates unique filenames
   based on the pathname  of the scratch directory, process
  (or thread) number, and a random number. On busy Windows systems
   which are using multibyte character sets, customers have
  observed scratch file names which contain invalid unicode
  characters.
   This led to error messages like:
   APT_CombinedOperatorController,0: Invalid character(s)
  ([xFFFD]) found converting Unicode string (code point:
  C:/TMP/scratch/tsortG6bOSPC[xFFFD]_20170214130147.779000_7840_13
  9430872) to codepage ibm-943_P15A-2003

Problem conclusion

• The scratch file generation code was changed to use character
  conversion routine instead of type casting when creating the
  file name.
  Patches are available which fix the problem.
