1.想问一下.为什么直接执行就报错？
ulimit -c 2048
[oracle@boss ~]$ ulimit -c 2048
-bash: ulimit: core file size: cannot modify limit: Operation not permitted
2.想问一下solaris下改某一用户的limit 标准方法是什么？

$ ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) unlimited
stack(kbytes) 8480
coredump(blocks) unlimited
nofiles(descriptors) 1024

Step 2:modify file /etc/system(login as root) .Then reboot pc, that’s absolutely necessary.

#vi /etc/system
*set Hard limit on file descriptors
set rlim_fd_max=8192
*set soft limit on file descriptors
set rlim_fd_cur=4096

#reboot

Step 3: check current status again login as both root and common user
