Use sar, iostat, etc. to characterize your problem. 1) use a utilty like jprobe or optimizeit to see what your app is doing 2) Use the unix command "truss" (RTFM) 3) I don't know about HPUX, but Sun has a suite of utilities in /usr/proc/bin that allow you to snoop into a process. Perhaps HPUX has something similar.
