RE: OEM Events

But again, how often does the Application *needs* to drop a table in a Production environment? Why?  

And does the time to drop tables in a Development/Test environment matter that much?

Just my thoughts ;)

"segments with extents > 25% of max_extents [yes, this is a really low threshold]"
catches the application much before it can crash.

Unlimited can result in tens of thousands of extents and someone then wanting to drop the table. In Dictionary Managed tablespaces, there's no point in allowing very many small extents. If my script catches such tables early, I can modify the NEXT_EXTENT so that extent growth isn't too great.
