PH67993: INCORRECT EVALUATION OF CURRENT_DATE, CURRENT_TIME AND CURRENT_TIMESTAMP IN NATIVE MODE IN Z/OS 3.2

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A logical unload specifying a SELECT statement that involves the
  use of CURRENT_DATE, CURRENT_TIME and CURRENT_TIMESTAMP special
  registers and that is performed in native mode produces
  incorrect unloaded data when run in z/OS 3.2.
  
  This problem can affect any logical unload that uses SQL
  expressions involving any of the three aforementioned special
  registers, whether to define the selected items or in a
  predicate of a WHERE clause. The incorrectness of the unloaded
  data can consist in improperly filtered rows and/or in incorrect
  data for the output fields related to columns defined with SQL
  expressions using the special registers listed above.
  
  This occurs because Db2 HPU unduly detects an error when
  retrieving the system time value needed to calculate the value
  of the CURRENT_DATE, CURRENT_TIME or CURRENT_TIMESTAMP SQL
  special registers which triggers the erroneous error processing
  described by APAR PH67989.
  

Local fix

• - If applicable, consider performing the unload in SQL mode by
    specifying the DB2 FORCE option.
  
  - If Db2 HPU is at the maintenance level UO04514, apply the
    following ZAP:
