I am using Postgresql 7.3.2 on Solaris 5.9 compiled with gcc and solaris ld. Right now, our max number of connections and buffers are set to the default, which is 32 for connections and 64 for buffers. I want to be able to increase that to 100 Max connections and 200 max buffers, but when I do that.. i get this:
IpcSemaphoreCreate: semget(key=5432004, num=17, 03600) failed: No space left on device
This error does *not* mean that you have run out of disk space.
It occurs when either the system limit for the maximum number of semaphore sets (SEMMNI), or the system wide maximum number of semaphores (SEMMNS), would be exceeded. You need to raise the respective kernel parameter. Alternatively, reduce PostgreSQL's consumption of semaphores by reducing its max_connections parameter (currently 100).
How do I increase the mentioned kernel values on solaris to be able to increase the number of connections I need?
TIA,
