RE: Monitoring Unix Question
Sthepen : I am very thankfull for you help ... But it is not all... Imagine you working at environment that doesn't know the database, and need to solve problems. So, the CPU is a item that you helped me to find out the user that is using it a lot, and in general, what more can i do, thinks like that : 1.) the average of load of the server 2.) disk i/o using 3.) the swap in disk of the memory Best regards Eriovaldo If you have the top utility installed on the Unix box, thi s makes an easy to use interface to identify CPU hogs. For non- root users to run it, your sys admin might have to change default permissions on certai n files such as /dev/kmem; or possibly make top SUID root. If you don't have top, or you can't run it as non- root, you can try using the following ps command to sort things by % CPU, but I think there might be differences among OS's on some of the more exotic ps and sor t options: ps -eo pid -o %cpu | sort -rk2 | head -20 After you have identified which PID is the hog, and can see that it is a dedicated server process, you can run something like the fol lowing to match SID SERIAL# to the correct OS process ID.

Re: Monitoring Unix Question
In V$PROCESS there is SPID (or something similar) which is the OS pid. Then, you can join to V$SESSION on ADDR / PADDR hth connor --- ecandrietta [EMAIL PROTECTED] wrote: Friends : How can i do for get what is running inside a PID that is using a lot of CPU ?
