PH07884: PADDING OF VARGRAPHIC, WHERE CLAUSE ON VARGRAPHIC AND DATA TRUNCATION OF GRAPHIC/VARGRAPHIC CAN BE INCORRECT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Due to the wrong handling of the situation when an assembler
  instruction returns 'CPU-DETERMINED COMPLETION' the following
  issues can occur:
  - when a GRAPHIC or VARGRAPHIC column is truncated, the return
  code associated to this truncation can not comply with the
  applicable LOSSCHAR value (set via either the LOSSCHAR option or
  VUU0471/LOSSCHAR parmlib parameter).
  - When a VARGRAPHIC column is used in a predicate of a WHERE
  clause and the applicable DBCS padding character set through the
  PADDING option does not consist in a duplicated single byte (in
  other word, the first byte of the sequence is the same a the
  second one), the unloaded rows might not comply with the
  search-condition of the WHRE clause.
  - when unloading VARGRAPHIC data in UNICODE requiring padding,
  data can be incorrectly padded (with less padding character than
  expected)
  
  The latter issue occurs only in HPU 5.1 after the PTF UI58156
  for APAR PH01899 has been applied.
