Q1: When a running process hogs a CPU, I would like to be able to reduce its % CPU consumption, say to 50%. Is there a command to do this or this is possible in Redhat (& CentOS & HP-UX if anyone knows) ? if we started a process / script using "nice", say "nice ./scriptname", it will give the process a lower priority (I think) so that other processes will get a higher priority to use the CPU but still a nice process will chew 100% of the CPU when no other processes are using it, correct me if I'm wrong. My purpose is so that we don't get a lot of alerts - having said this, it makes sense to tune the monitoring tool's threshold but it takes a while to get the tuning approved. I'm looking for quick interim fix to reduce the overwhelming alerts though this does not address the root cause. The best idea I can find so far to achieve this is the link below to put it in the code as follows but this is still short of a quick fix : http://unix.derkeiler.com/Newsgroups/comp.unix.solaris/2006-10/msg01405.html Q2: One thought : can a running app (eg Websphere, Weblogic, Tomcat, Oracle instances) be set such that it uses only a specific processor in a multiple processor environment : the averaged value of all the processors can then show a lower average CPU utilization. The other lower CPU hungry process can be shifted to one processor and those savage ones restricted to 1 or 2 processors : I'm not sure if this manual reshuffling is more efficient that letting the system manages it on its own but just soliciting views. In some cases, I can't kill or restart resource hungry processes, just looking for ways to mitigate the situation -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
