I need a script that will change the limits in the /etc/security/limits file. Primarily the files limit must be unlimited (-1). I have a list of server names that I would like to tie into the script. Each server will be accessed via remsh. Also will I need to reboot in order for the changes take place or can I just restart a service?

Any help is appreciated.

Thank you,

You can use perl, sed, awk to edit the file but I believe the correct method should be to manually change the value for the default stanza then change the value of the attribute via the chuser command on a user by user basis.

chsec is your friend. (better than chuser for this task)
use remsh/rsh/ssh ... it's your choice
you can reboot OR restart some services ... it's your choice.
Please, could you repeat the question with other words?

What services would need to be restarted to avoid a reboot. I have also place a copy of the scripted I created in the message. Any suggestions? Just to clarify this script is ran on a HP-UX server but is connecting to a bunch of AIX 5.2 servers.

#! /bin/sh
for sys in $(<Bad_servers.test); do
remsh $sys -n "cp /etc/security/limits /etc/security/limits.old; u limit -1 > ul
imit.change.log 2>&1"
done

better use chsec:

chsec -f /etc/security/limits -s default -a fsize=-1
chsec -f /etc/security/limits -s root -a fsize=-1
The limits are evaluated every time you read the environment (during login or /bin/su -).
Just stop and start Oracle, logout&login etc.
