Is there an equivalent PRM (process resource manager) on RHEL to cap a user's/app's Resource Usage

[Alzhy]

My client is concerned that in light of recent events where it is far easier to "hang" a Linux system than UNIX -- if there is a similar implementation for resource capping in RHEL systems.

On HP-UX, we empooy PRM (Process Resource Manager) - where users can be mapped to resource caps like CPU for example. So during extremely busy siutations, a parituclar user will never be starved for resources or will never hog ALL CPU resources.


Is there such a similar facility on Linux?

Looks like there is:

BUT only with RHEL 6 ;^(

Maybe you can use cpulimit to distribute your resources evenly amongst the users.

(I have not tested this program)
