We are running Red Hat 5.7 and are trying to find a way to
determine what a process was running that was assigned to a certain  PID ??

We believe this was a process that crased the Oracle Database, we have found in some
Oracle logs the PID, but can't determine what that PID was...

Is there a way to get this out of the sar file for that day ???

Thanks

have you read http://www.unix.com/red-hat/43718-how-find-out-process-id-particular-one-file.html great comment there
You need to use the 'a' option to see the processes by all users and the 'x' option to show all of the processes outside of the scope of the shell.
# ps -ax

If you just run that command as is, the results will just scroll by.

In order see and browse the results at you own pace you can pipe the list into 'less'.
# ps -ax | less

Or if you want to search for a particular application process, instead of piping in 'less' you can pipe the results into grep.
# ps -ax | grep search

For example I can find the process id of Firefox by doing something like this:
# ps -ax | grep firefox
3399 ?? S 3:30.90 /Ap ... OS/firefox-bin -ps ...
3456 p1 S+ 0:00.00 grep firefoxthis will solve your problem.

I can find a running process, what I need to know is if there is a way through sar or some other history on the server to find a process that was running a few days ago ??
