>I want to change the data & stack values in acn123 server, to the same as acn120.

(You should be looking directly at the kernel parms, not ulimit.)

Your value of maxdsiz is at its max on acn123, so you only need to change maxssiz:
kctune maxssiz=$(( 131072 * 1024 ))

If you want to make sure the 64 bit values are the same you need to use:
kmtune | grep -e maxssiz -e maxdsiz

Then use kctune(1m) to set them on acn123.

You should check the relevant kernel parameters. User parameters can not exceed the limits imposed by kernel.

Best regards,

Hi ftp ,

you should first extend the value of both maxssiz and maxssiz_64bit , then you will be able to increase the stack limit , also there are many post on this topic if you try Mr. Google witha " + itrc" flag.

I suggested you NOT use ulimit but only use kctune(1m). And I provided the command.

Hi,

Am edit the profile and added the below entry but not updated.

uname -a
HP-UX acnux06 B.11.31 U 9000/800 185074309 unlimited-user license

ulimit -d 4294705152

>ulimit -d 4294705152
sh: ulimit: The specified number is not valid for this command.

echo $SHELL
/sbin/sh

so I need to increase the data to 4294705152 and stack to 131072?

Thanks in Advance !!!

>Am edit the profile and added the below entry but not updated.

You don't edit any profile. As root you must execute kctune(1m).

>so I need to increase the data to 4294705152 and stack to 131072?

No (for data)!
Please read what I said. You can't use ulimit to increase the value. Only kctune(1m).

Note: ulimit is broken on 11.11 and returns a bogus value of 4294705152.
On your 11.31 system you have 4194300, the maximum value for ulimit and 32 bit.
