Must be missing something but ... what is the link with OBIEE? As you posted in the Business Intelligence Suite Enterprise Edition (OBIEE) space (and it's not easy to get down till here by mistake as it's 2-3 levels deep in the BI space)
If there, as it seems, no link with OBIEE at all you maybe want to consider to move your thread to SQL Developer
Thanks alot for sharing this info. I will try this and get back incase of any queries.
