we have following setup on sysctl.conf: kernel.sem = 256 32000 128 142 I tried to startup database and have error happen. I knew problem come from SEMMNS (32000) is not enough. Does anyone know how to calculate how many semaphores already use on system?

Ole, Semaphores are a very cheap system resource in SunOS 4.1.x. You can easily bump up the max number using adb, without even recompiling the kernel. _seminfo: _seminfo+0 semmap 30 _seminfo+4 semmni 256 _seminfo+8 semmns 1024 _seminfo+0xc semmnu 1024 _seminfo+0x10 semmsl 1024 _seminfo+0x14 semopm 100 _seminfo+0x18 semume 256 _seminfo+0x1c semusz 2064 _seminfo+0x20 semvmx 32767 _seminfo+0x24 semaem 16384 To set "semmns" and other parameters without recompiling the kernel, do somthi...

Hello, I have the following entries in /boot/loader.conf: kern.ipc.shm_use_phys="1" kern.ipc.semmns="500" kern.ipc.semmni="40" kern.ipc.semmap="500" which are set correctly. Unfortunately, the following two entries kern.ipc.shmmax="512000000" kern.ipc.shmall="65526" do not change the corresponding values according to sysctl, no matter w...

Hello all, I have a very annoying situation (at least at my end). I set up Samba 2.0.5 on a Digital UNIX 4.0F system sitting on a Compaq DS20 server with great success.... until recently. I set up three directory file shares with no problems, when I tried to set up a forth, quite a while after setting up the inital three, I tried to access it from a NT box, I got the message server not found,
