hi all, i've successfully built postgreSQL 7.3.2-STABLE on Mac OSX 10.2.4. much trouble launching it led me to the discussions (<http://www.postgresql.org/docs/view.php?version=7.3&idoc=1&file=kernel-re sources.html>) on setting shared memory parameters -- especially SHMMAX -- in OSX's "/System/Library/StartupItems/SystemTuning/SystemTuning" so, as instructed, i changed the defaults (near the bottom of SystemTuning): sysctl -w kern.sysv.shmmax=4194304 sysctl -w kern.sysv.shmmin=1 sysctl -w kern.sysv.shmmni=32 sysctl -w kern.sysv.shmseg=8 sysctl -w kern.sysv.shmall=1024 to: sysctl -w kern.sysv.shmmax=33554432 # bytes sysctl -w kern.sysv.shmmin=1 sysctl -w kern.sysv.shmmni=32 sysctl -w kern.sysv.shmseg=8 sysctl -w kern.sysv.shmall=8192 # 4K pages and defined (in postgresql.conf): shared_buffers = 2048 max_coinnection = 1024 and rebooted. unfortunately, immediately after system launch, i still couldn't launch postgres eventually, a random check with "sysctl -a" gave: kern.sysv.shmmax: -1 kern.sysv.shmmin: -1 kern.sysv.shmmni: -1 kern.sysv.shmseg: -1 kern.sysv.shmall: -1 OBVIOUSLY, a problem! i CAN enter the sysctl settings at the command line, verify success with 'sysctl -a', and then postgres launches/operates just fine ..... QUESTIONS: any idea why these setting are being written at boot to values of "-1"? how do i get these setting to 'stick'? thanks, richard _______________________________________________ darwin-kernel mailing list | darwin-kernel@lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/darwin-kernel Do not post admin requests to the list.
