Over a period of about 5 - 8 minutes what does the paging/faulting look like? If you can copy the text to the list showing all of the WRKSYSSTS output then the answer of how much memory for interactive is a bit easier to answer. The WRKSYSSTS screen will tell us quite a bit. (I always change the font to fixed when I paste it to keep columns in line) By the way, while your taking the sample, don't refresh constantly. Only refresh a couple of times during the observation. Refresh can actually alter the results of the sample enough to toss off any analysis.

No, almost no SQL in our environment. It did drop from 21 to 19 in the 30 seconds I watched (hence "about 20" in my response), but I don't know what is typical. Right now, it's ~27GB for 936 users.

Sean,

That seems pretty high to me....

Do you by chance have a lot of SQL used by your interactive programs?
