Re: lack of memory

Hi Deepak,

I'm on Linux. I'm afraid it's not accurate calculation because 'processes' parameter just get you
upper limit on number of connections and a session only keeps its 'sort_area_size' untill a sort
operation completes. Does pmap utility exist on Linux? I'll check it tomorrow (i'm at home now).
Thanks for your reply.

Ed
