Symptoms

On systems where OLS is installed the constraint check fires the SELECT VPD policy defined on the parent table, this may result in unexpected error ORA-28117 "integrity constraint violated - parent record not found" .

 Create the policy function and the tables :

After searching within v$SQLAREA with SQL_ID, following SQLs were found: 

02b8139tjanr9 = INSERT INTO T1(NPKID) VALUES (1001) 
9k2u3b033rb0z = INSERT INTO T2(NPKID, NFKID) VALUES (2002, 1001) 

Changes

 Differences in behaviouir are typically seen between systems where VPD policies exist on table with FK constraints and only some have OLS installed.
