Thanks Dave, I'm aware of "renice" when I mentioned "nice" in the first post but "renice" is probably not what I'm looking for because when no other processes need the CPU, this reniced CPU hungry process would still chew up all the CPU, resulting in the frequent alerts I'm getting. Cameron's stutter script of staggering between "kill -SIGSTOP pid" "kill -SIGCONT pid" would meet my requirement for other UNIX (HP-UX etc) platforms as well; due to corporate approval processes, I haven't got a chance to test it on HP-UX yet to see if the Websphere & Weblogic processes cope well and with smaller intervals, hopefully it's not noticeable to users.
