I don't know if this will work for SPARC Solaris, but this is how I did it on Intel Solaris.
To see your current settings for your kernel parameters, type sysdef | grep -i <param>
ex. sysdef | grep -i semmsl

To change your values, as root, edit your /etc/system file. set semsys: seminfo_semmsl=25 (or whatever you want to change it to) set semsys: seminfo_semmns=1750

You will need to relink your kernel to have these take effect. Be sure you do this with your sys admin!
