We ran into the problem of having an ungodly amount of memory allocated to each of our users sessions as well. What I had to do was to to into SMITTY and modify the MBUFFS parameter under the environment. Apparently, if MBUFFS is set large or wide open , Oracle will take ALL YOU GIVE IT. We had MBUFFS set to 65 Megs, so each oracle session was allocated , at a minimum, 65 megs. Used up memeory real fast.

Hi All,

Can somebody enlighten me what is included in the memory usage per session.

We have a sort_area_size of 1M and have found sessions that have as much as 200Mb memory usage (Exceptional) and 20-40Mb on regular basis.

TIA Jack
