Re: How to change the ulimit for all users

you can put your ulimit command in /etc/profile or in individual user profiles to make these changes permanent.

You can put your ulimit commands in user's $HOME/.profile directory or add them to /etc/profile to make permanent. If specific user(s) need specific ulimit values, place the appropriate tests in /etc/profile.

Hope this helps.

Re: How to change the ulimit for all users

Hi,

U can check the ulimit value by:-

# ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 262144
stack(kbytes) 98252
memory(kbytes) unlimited
coredump(blocks) 4194303
nofiles(descriptors) 2048

If you want to change any parmeters you can use intial character like.

time(seconds) #ulimit -t limtvalue
file(blocks) #ulimit -f limtvalue
data(kbytes) #ulimit -d limtvalue
stack(kbytes) #ulimit -s limtvalue
memory(kbytes) #ulimit -m limtvalue
coredump(blocks)#ulimit -c limtvalue
nofiles(descriptors)#ulimit -n limtvalue

e.g
#ulimit -c 2048
It will limit the coredump size to 2MB

For Each Single User.

Do you want to increase or decrease the values?
The defaults start with the various kernel parms.

Hi,

Remember, using switches with ulimit command depends on the shell.
