[root@web root]# ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
file size (blocks, -f) unlimited
max locked memory (kbytes, -l) 4
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
stack size (kbytes, -s) 10240
cpu time (seconds, -t) unlimited
max user processes (-u) 7168
virtual memory (kbytes, -v) unlimited

You should do it in two places:

1) /etc/security/limits.conf

2) sometimes there is "ulimit" commands in /etc/bashrc & bash_profile

when I editted /etc/security/limits.conf

Q1) Dose system have to reboot?

I want to change core dump file specific user, Not all users.

Q2)So when I do that what you tell me, Can the system generate core dump file next time.?

No, just re-login, PAM uses this file during user login.

read comments into limits.conf, it's doable

for procecces of this user - yes.

After editing limits.conf and relogin just run "ulimit" - you should see unlimited core size.

Hello!

I think is best to set the core limit into the .bash_profile of the specific user, not to all users or to the system.
