To limit some user

[cfeitosa]

Hello guys!

I'm using HPUX 11.11

Is it possible to limit some user for someones applications, process and so far and so on?

For example... If the user XYZ try to start a process that consume 1GB of memory and 80% of CPU he doesn't will success because I've limited it like:

User: XYZ (*process)
Memory: <= 800MB
CPU: <= 50%

And I don't know if I've explained from a right way but basically what I want is to limit some users through of HPUX and using resources of HPUX.

Please, could someone give me a help?

Thanks!!!!

Have you looked at Process Resource Manager and or Work load manager? Between the two of them, you should be able to do what you want.

They are included in the higher end HPUX OS's. If you do not have them they can be purchased as well.

Anything is possible but it's rather difficult to even define things like memory <= 800MB. Does that mean physical memory or virtual memory? How do you calculate it?

There are some add-on products that do this sort of thing:

Look for Process Resource Manager (PRM) and Workload Manager (WLM).

You can of course limit his memory usage with maxdsiz set with ulimit -m. Set in /etc/profile by testing $LOGNAME.

In /etc/profile so it can't be bypassed:
name=$(id -u -n)
case $name in
name1|name2|name3)
# set the maximum data area smaller for these
ulimit -d 300000 # size in Kb
;;
esac

The above code sets the ulimit data size to 300Mb for the users name1, name2 or name3.
