how to calculate how many semaphores already use on server?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



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?
Thanks.
