[SunHELP] tunable semaphore parameter

We need to reset the value of "semmns" for an application to work, we are getting semaphore errors and Adrian Cockcroft's book "Sun Performance & Tuning" recommends setting this value higher than we have it.

Proceeding with caution, I would like to verify that the correct syntax in the /etc/system entry would be;

	set semmns=250

The value was determined as being the product of (semmni X semmsl), this is for a UE 450 with 128 mb RAM running 2.6.

Is this the correct syntax? Thanks.
