I am facing a strange problem of CPU spikes every 12-13 mins. This is a sun fire V210 machine (with 2 processors) and solaris 8. (5.8 Generic_117350-26 sun4u sparc SUNW,Sun-Fire-V210)
I have oracle, tomcat and a client-server (c++) application with few threads running on the system(this is a simple messaging application). I tried monitoring with prstat -Lm 1 but that shows me every thread of the application pretty much consuming consistent cpu (user and system). mpstat however do shows the spikes happening 12-13 mins. i am unable to catch the culprit. i do see the prstat -m shows ICWX (involuntary context switches) for application threads incrasing during the spike and so does the latency (it goes from 0.0 to 4.5). How do i catch the culprit. my oracle is pretty much supposed to be idle, so does the tomcat/ java and any other process. Any help/pointers are greatly appreciated. thanks rp.
