Operating Systems Solaris Do I need to reboot Solaris 10 server for changes in /etc/systems ? Post 302174630 by synchro on Tuesday 11th of March 2008 04:28:28 PM

You could also take a look at using projects in Solaris 10 (projadd, projmod, projdel) which just edit /etc/project, but in a safe way. Then you can control almost all kernel parameters and you do not need to reboot to use or change them. You will need to relaunch the process(es) after you make the change, but you do not have to reboot. There is a whole section in the Solaris 10 manual about using projects. What is even better about them is you can assign them to users, groups, processes, groups of processes, etc. and give different projects different kernel params or different users hard stops on using system resources without messing with containers or domains and what not. So for example, you could tell the oracle user that it has 3GB of RAM and the jboss app server it has 2GB of RAM and they will not fight each other.
