How to increase hard limit values at user level?

[Phani kumar V]

We are facing the following error

ulimit -n 65535
sh: ulimit: The specified value exceeds the user's allowable limit.

at root it set to 65535 but at user level we are unable to do that.

do we need to reboot?

os version: hp-ux 11iv3

Why don't you try setting it to unlimited.

ulimit -n unlimited

Hi,

hardlimit of file descriptor value is limited to kernel parameter value maxfiles_lim. You cannot set the hard limit value more than maxfiles_lim value.

To view the hard limit values for a particular user.

$ulimit -Ha

To set the hard limit value for a particular user

$ulimit -Hn

You cannot set this to unlimited for non-root users.

Check the current value of maxfiles_lim.

# kmtune -q maxfiles_lim

You can't. That's why it's a hard limit.

>do we need to reboot?

No, it's a dynamic tunable. But you will have to relogin.

That's kctune(1m) for 11.23/11.31.
