I'm not convinced that you even need to go thorugh all of this. As long as you have "create or replace" in all of your source code there really isn't any need to drop the procedures/packages before you do a re-compile unless you are so tight on space in your system tablespace that you have no room for a compile. I think if you just allow the procedures to be replaced you'll end up using less time overall. ------------------------------------------------------------------------------------------------- - ------------------------------------------------------------------------------------------------- - ------------------------------------------------------------------------------------------------- - ------------------------------------------------------------------------------------------------- - ------------------------------------------------------------------------------------------------- - ------------------------------------------------------------------------------------------------- - ------------------------------------------------------------------------------------------------- - ------------------------------------------------------------------------------------------------- -------------------------------------------------------------------------------------------------
