Limiting number of processes per user

[Edgar Brito]

Is it possible to assign a different limit of processes allowed to different users. For instance, user1 would have a limmit of processes allowed. User2 would have another limmit of processes allowed.

I know maxuprc can limmit the proccess for users, this limit is the same limit for all users.

How could I define different limit of processes allowed to different users?

Is it possible at OS level?

Does exist a tool for doing this? Can this be done with gWLM?

I will apprecite your help.

Regards.

Shalom,

Yes,

It is called maxuprc.

By default it is set to 75.

That applies to all users.

Except root.

Problem is it is system wide, and can not be set for individual users.

Setting it to say 10 would prevent oracle from running a database since the oracle user for any server usually requires more processes than that.

Steve,

That would set it on a system wide basis. However, the question is: can it be done on a user by user basis and I know of no way to accomplish that.

Could it be done defining a policy in gWLM?

[Duncan Edmonstone]

What are you actually trying to acheive here?

Are you attempting to limit the number of CPU cycles any given user can take?

If yes, then absolutely a gWLM policy could do this, as could PRM...

The idea is to limit number of processes for user1 so user2 has more room to run processes.

[Duncan Edmonstone]

what do you mean by room? CPU cycles or memory? or both?

either way, I thinl PRM is what you are looking for here:

Yes: a Baseball Bat.

Threaten the users.
Make them behave!

or, as Duncan mentioned: HP Process Resource Manager
