You can try mpsched and mpctl(2) in HP-UX. http://docs.hp.com/en/B2355-90689/mpsched.1.html [snipped] However, I'm also looking for similar solution for HP-UX and Cameron's method could port easily to HP-UX. Anyone know what's the equivalent for taskset in HP-UX? Sorry that this is a Redhat & not a HP-UX list.

'taskset' will fulfill my needs well too. Cameron was trying to fulfill what I wanted : a)stopping those annoying alerts b)if there's constantly other processes that takes up CPU, then renice will probably deprive this 'reniced' processes a lot of the CPU resource. I want to be able to control it manually using his script (or for Linux, someone else in the Net has cpulimit.c codes that also fulfill what I need) c)there's concern that if a novice were to do 'renice' of a "shared" server process, such as a Webserver or Oracle server and the server process turn out to get very little CPU allocation due to other processes need the CPU often, then I would rather to be able to control it manually (ie using stutter or cpulimit) than let the system decides it for me (ie using renice) just get to know taskset which will meet my needs for a, b & to an extent c as well. However, I'm also looking for similar solution for HP-UX and Cameron's method could port easily to HP-UX. Anyone know what's the equivalent for taskset in HP-UX? Sorry that this is a Redhat & not a HP-UX list. To mitigate the situation where a process needs to talk to another periodically, I thought of using Cameron's solution with very short intervals (0.1 to 0.2 secs) on HP-UX. For Linux, taskset is good -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
