	Thanks Tanel, that's a great idea and seems like it would work

very well for testing, but in some cases I actually need to do this in production (I forgot to mention that in my original post) in order to reset a poorly performing execution plan so the bind variables will be peeked again and Oracle will come up with a more appropriate plan. This is where I really need to prevent the mass invalidation of all cursors dependent on a given object and I can't use the view method here with the COTS app. I wish Oracle would just add a simple procedure like dbms_shared_pool.invalidate('<hash_value>'). It seems like it would be simple and useful enough. I can't be the only one encountering this problem. Maybe I'll open an enhancement request and see how that goes - never tried one before.          

        Looking forward to your published paper, although it sounds like it might not be safe for a production environment ;-) I
