Hang on, are you saying you are using TCP for local connections? Why don't you use stream pipes? Adding multiple listeners is only really useful if you have multiple network cards. I don't think you are going to see much gain with local connections unless you have 1000's of users. > I don't recall ever seeing anyone suggest > multiple listener ports as a tuning option so I'd be interested to > hear your thoughts. It is certainly a concept covered in the Sys Adm training course. Cheers, -- Mark. +----------------------------------------------------------+-----------+ | Mark D.
