Mark, I don't know if this is what you want, but with solaris, I can see what is
the current setup using "sysdef". At the end of the output, I have this:
*
* IPC Semaphores
* 128 entries in semaphore map (SEMMAP) 128 semaphore identifiers (SEMMNI) 8192 semaphores in system (SEMMNS) 8192
undo structures in system (SEMMNU) 64 max semaphores per id (SEMMSL) 32 max operations per semop call (SEMOPM)
32 max undo entries per process (SEMUME)32767 semaphore maximum value (SEMVMX)16384 adjust on exit max value
(SEMAEM)
*
* IPC Shared Memory
* 16777216 max shared memory segment size (SHMMAX) 1 min shared memory segment size (SHMMIN) 100 shared
memoryidentifiers (SHMMNI) 51 max attached shm segments per process (SHMSEG)
*
* Time Sharing Scheduler Tunables
*
60 maximum time sharing user priority (TSMAXUPRI)
SYS system class name (SYS_NAME)
