Hi all, I'm trying to configure and tune postgresql on FreeBSD 4.9. We want to allow at least 128 concurrent connections but preferably 256.
Looking at the documentation, we should be okay if we set the following in our kernel to achieve this: kern.ipc.somaxconn = 512 kern.ipc.shmall = 65536 kern.ipc.shmmni = 128 kern.ipc.semmni = 8 kern.ipc.semmns = 256 Now, I have three questions... 1. Why do we have to set these in the kernel ? Why does setting them in /etc/sysctl.conf or /etc/loader.conf not work ? 2. Is there a recommended list of settings that we should use in our kernel to allow 128 connections and 256 connections ? and lastly, 3. What is the impact on the rest of the system likely to be by setting aside this memory as shared memory ? Is it then no longer available to other applications like Apache and Exim ? Are there any other performance issues that we should be aware of ? Regards, -- Wayne Pascoe Be nice to your daemons. _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
