Answer 1

CAUSE
The problem is caused by not using VALID dates values in the dataset.
- This data problem was masked in the original version as the Predicate(s) used can change between versions of Oracle
- Oracle does *not* guarantee the same explain plan or the specific order of predicates used between versions of Oracle
Reviewing the  EXPLAIN PLAN for both versions revealed in this case:
1) The table was partitioned
2) The EXPLAIN PLANS were not the same due to how the partitions were accessed
3) If the same query was used against a non-partitioned table using the same data, the following error would always occur
   ORA-01843: not a valid month
4) The problem string value was in this case found to include the string value of  '0000-00-00'
  The ORA-01843 occurred when using the TO_DATE function against '0000-00-00'
There is *no* Year= '0000' Month= '00' or day = '00' -- therefore the  ORA-01843: not a valid month
