OK, that is 1mb for each connected user session. What I am really looking for is the over head of just the parameters without connected sessions. For the version in question (11.1.0.7) I do not have a test system available to try it. L

In Oracle 10g dedicated system, by default each connected user session uses 1MB memory.

What is the memory overhead of increasing processes and sessions ? Say I current have 1000 sessions and I want to increase that to 2000 sessions: how much extra memory would I use assuming no additional processes sessions are really used ?  

I used to recall in Oracle 7/8 days that it was a trivial amount- like 8 bytes, or 80 bytes, or something small. But I am not sure I am remembering correctly....
