Hi, I'm trying to figure out what some reasonable settings would be for kernel parameters like shared memory and max open files. I've read the section of the manual but it doesn't seem to give any rule of thumb based on number of users or frequency of queries. With my load testing I definitely bump up against the max open files problem but I'm not sure about the shared memory. I'm running linux (redhat 6.1) If you have a high volume production system, can you post your parameter settings and anything you tweak at startup? Thanks, Alex. ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
