JR42236: PROBLEMS WITH TRANSFORMER NULL TESTING EXPRESSIONS WHEN RUNNING WITH APT_TRANSFORM_COMPILE_OLD_NULL_HANDLING SET.

IBM InfoSphere Information Server, Version 8.7 Fix Pack 1
IBM InfoSphere Information Server, Version 8.5 Fix Pack 3

APAR status

• Closed as program error.

Error description

• InfoSphere Information Server 8.5 changed how the parallel
  engine Transformer stage handles columns that contain null
  values. These changes were described in Tech Note 1514921.
  
  Since InfoSphere Information Server 8.5 shipped,  issues in the
  default null handling behavior of Version 8.5, and problems with
  the implementation of the InfoSphere Information Server 8.1
  compatibility mode  were discovered .
  Jobs that process nulls in Transformer stages show different
  behavior when migrated from 8.1 to 8.5, even when legacy null
  handling is set.
  
  In IS 8.1 Nulls can be converted to other values using any of
  the following 3 functions:
   NullToEmpty()
   NullToZero()
   NullToValue()
  
  Even with  APT_TRANSFORM_COMPILE_OLD_NULL_HANDLING  set, in IS
  8.5 these functions do not work the same way they did in
  InfoSphere Information Server 8.1 . The fix for this APAR
  restores this compatibility.
