Is there a way I can assign processes to different processors? I know in windows xp you can set process affinity, and wondered if there is a *nix equivelant. (2 Replies)
I am running solaris 9 on a SUn 480r. It is running SAS statistical software, these processes in full flow normally run at about 50-60% cpu (theres nothing else really running on the box) this is fine, and the SAS jobs get run nice and quick. However over the last few weeks everytime a SAS job is... (1 Reply)

I'm trying to monitor the CPU usage of a process and output that value to a file or variable. I know topas or nmon can tell me this in interactive mode but what I need is topas-looking output that allows me to write to a file after a discrete interval. Unlike nmon data collection to a file on top... (5 Replies)

Hi,
I have a unix script that basically has a while loop inside which it checks Oracle database for certain records. If it finds the records, it does some processing and then goes back to the while loop. If it doesnot find any matching records, then it sleeps for 30 seconds and then goes back to... (17 Replies)
Can someone please help me with a script that will help in identifying the CPU & memory usage by a process name, rather than a process id.This is to primarily analyze the consumption of resources, for performance tweaking.

cpu
CPU(1) General Commands Manual CPU(1)NAME
cpu - connection to cpu server
SYNOPSIS
cpu [ -h server ] [ -c cmd args ... ]
DESCRIPTION
Cpu starts an rc(1) running on the server machine, or the machine named in the $cpu environment variable if there is no -h option. Rc's
standard input, output, and error files will be /dev/cons in the name space where the cpu command was invoked. Normally, cpu is run in an
81/2(1) window on a terminal, so rc output goes to that window, and input comes from the keyboard when that window is current. Rc's cur-
rent directory is the working directory of the cpu command itself.
The name space for the new rc is an analogue of the name space where the cpu command was invoked: it is the same except for architecture-
dependent bindings such as /bin and the use of fast paths to file servers, if available.
If a -c argument is present, the remainder of the command line is executed by rc on the server, and then cpu exits.
The name space is built by running /usr/$user/lib/profile with the root of the invoking name space bound to /mnt/term. The service envi-
ronment variable is set to cpu; the cputype and objtype environment variables reflect the server's architecture.
FILES
The name space of the terminal side of the cpu command is mounted on the CPU side on directory /mnt/term.

Binds and mounts done after the terminal lib/profile is run are not reflected in the new name space.
