linux kernel parm: max processes

[D Block 2]

Can you change max user processes on the fly using /proc ? How-To?

Also, is there a document reference that details this method and also to configure the kernel tuneables ?

Using AS 3.1

To keep it short have a look at
man sysctl

Not sure what the variable name is, but you can view all the variables that are available to be changed, along with their current setting, using the command sysctl -a.

Don't forget that sysctl does not add changes made to the configuration file; this is left for you to do manually. If you want your changes to persist after a reboot, you must maintain this file.

Tom,

I forgot to mention... Check also this file:
/etc/security/limits.conf
and the ulimit command in bash

max process can be limited / configured depends upon the user or user can change them on the correspoding shell itself.

To manage from user shell then,

ulimit -u (max user processes)

To manage as user based one then,

Try to give control to users from admin user (root) on /etc/security/limits.conf

Example:

user1 nproc

We can know the system kernel configuration's with /sbin/sysctl -a
