Hello, I'm tuning some IPC semaphores parameters in 6.1-STABLE for a busy PostGreSQL server (8.1.4). I still now can not find the value range (exactly the maximum value) and its dependencies on other system wide parameters of these parameters: kern.ipc.semmni, kern.ipc.semmns, kern.ipc.shmseg and kern.ipc.shmmni. The server is a dual Xeon 3.6 with 8Gb of RAM. Please advice. PS. The last change for me is going to read the source code, but I hope that someone in this mailing-list would tell me where to read or would give a good answer. ----- With best regards, | The Power to Serve Nguyen Tam Chinh | http://www.FreeBSD.org Loc: sp.cs.msu.su |
