  * USERS AFFECTED: All DB2 11 for z/OS CHECK DATA utility users *
  ****************************************************************
  * PROBLEM DESCRIPTION: MSGDSNU733I erroneously issued during   *
  *                      a CHECK DATA utility, leaving the       *
  *                      table space in CHECK PENDING (CHKP)     *
  *                      when the indexed foreign key (FK) is    *
  *                      null.                                   *
  ****************************************************************
  * RECOMMENDATION: Apply corrective PTF when available          *
  ****************************************************************
  A CHECK DATA utility was run on a dependent table with an
  indexed foreign key defined with ON DELETE SET NULL.  The index
  key included a variable column, but the foreign key did not.
  Rows were deleted from the parent table, causing null foreign
  key values.  The CHECK DATA utility issued DSNU733I - ROW
  (RID=X'nnnnnnnnnn') HAS NO PARENT FOR table in error, and
  placed the table space in CHKP, ending with RC4.  Null values
  should not have been flagged as a referential integrity error.
  
  The message was issued in error because CHECK DATA was not
  checking for nulls correctly.
  

Problem conclusion

• CHECK DATA utility code has been modified to correctly check
  for null indexed foreign keys.
