PM02601: RUNNING A JOB WITH FASTUNLOAD SYNTAX GENERATES ERROR MESSAGE INZU238E

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Running a job with FASTUNLOAD syntax generates the following
  error messages:
  INZU238E UNEXPECTED UNSUPPORTED SELECT
           UTILITY CANNOT SWITCH TO SQL PROCESSING
           REASON 0Xcfff4 / 0Xe501b80
  INZU366I UTILITY RETURN CODE 8 (REASON CODE 0x121a010)
  
  This fix changes HPU PIC behavior, as follows.
  
  * For FLOAT EXTERNAL output fields with the PIC('P', ....)
    option:
    - Before PM04338/UK56337, the first byte (i.e. sign byte)
      was incorrect for positive values and contained 0x00.
    - After PM04338/UK56337, the first byte (i.e. sign byte)
      for positive values contains the expected SBCS padding
      character.
  
  * For INTEGER EXTERNAL and DECIMAL EXTERNAL output fields
    with PIC('P', LEAD, , '00.0') or PIC('P', LEAD, , '00.Z')
    option:
    - Before PM04338, the first byte (i.e. byte sign) is
      incorrect for positive values and contains the leftmost
      digit of the integer values to be represented.
      If n is the length of the output field, positive values
      requiring n digits are not truncated.
    - After PM04338/UK56337, the first byte (i.e. sign byte)
      for positive values contains the expected SBCS padding
      character.  If n is the length of the output field,
      positive values requiring n digits are truncated, as
      expected.
  
  The word EXTERNAL used above means that the unload statement
  requires that the numerical data be written in a readable
  format by using any feature allowing it to do so
  (e.g. INTO clause, REFORMAT option, USER format, DELIMITED
  format...).

  1. inzctrl module was changed to handle constant fields
  correctly.
  2. inznode  and udbspgsq modules were changed to fix a problem
  with decimal expression scale determination.
  3. inznode to enhance numerical constants analysis.
  

Problem conclusion

• APPLY the PTF.
