HPUX 11:00 Ulimit Question

[LG Porter]

What is the process for defining the max. value for ulimit? What is the default and how is it set?

[Uday_S_Ankolekar · Accepted solution]

Hello,

From the knowledge base:

ulimit -s xxxxx where xxxxx is the number of kbytes to use cannot
exceed the system kernel parameter maxssiz. So if the ulimit is at
the value of maxssiz, then maxssiz will need to be increased. Note
that this requires a new kernel to be built and a reboot.

For example:

1. ulimit -a

time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 2015464
stack(kbytes) 81584
memory(kbytes) unlimited
coredump(blocks) 4290772993
nofiles(descriptors) 2048

2. echo maxssiz/D | adb /stand/vmunix /dev/kmem
maxssiz:
maxssiz: 20396

3. echo "4 * 20396" | bc
81584

Look at this thread below. Clay had given a good resolution.

Hi,

You can only use options when using the posix shell. Have a lokk at the man page 'sh-posix'
