If your users aren't complaining, you don't have a problem. :-) Because you have LRU_MIN_DIRTY and LRU_MAX_DIRTY set so low, your buffers are being flushed before they can, uh, buffer anything. If your system's performance is acceptable, I guess this is OK. You can amend the figures you're seeing by increasing BUFFERS or increasing LRU_MIN_DIRTY and LRU_MAX_DIRTY. >Also does anyone have some information about NETTYPE. We only have one >NETTYPE (VP class: CPU) in our onconfig. I see other people with 2 (CPU and >NET.) How do you determine what you need? You use a NET NETTYPE for client/server (TCP/IP) connections. If you're not using TCP/IP, then you don't need NET NETTYPEs. (I think it will automagically configure one by default anyway, can't remember the parameters off-hand.) ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
