   What is prompting you to increase OPEN_CURSORS? Is your application currently receiving an error from running out of cursors?

Hi all,

I'm trying to determine the resource footprint of a cursor - we're fiddling with open_cursors in init.ora, and I want to get an idea of the possible impact on memory, etc., if I bump this up from 100 to 500.

As these are allocated per session, I assume they probably consume stack or heap space in the PGA. Anyone know how much, or if there's a basic overhead + variable component based on SQL statement used?

Thanks
Fuzzy
:-)
