large_ncargs_enabled

[Shahul]

Hi

There is tunable parameter called large_ncargs_enable. Can anybody explain me what for this. In my system it is set to 0. I have a G class with 10.2.

Thanks in advance
Shahul

The argument list to anny command is by default max 20478 bytes.
If you set large_ncargs_enable to '1' the max length will be 20478000 bytes.

Sorry, I've not heard of this one. Unless there is some driver for it? Unfortunately 10.20 does not have a kernel parameter document
on-line, only 11.

Hi

From patch PHKL_16750 or PHKL_16751

700 or 800

When this patch is installed the default environment size is 20478 bytes. To enable the system to use the larger environment size of 2048000 bytes, the following steps must
be followed.

1. A new tunable called `large_ncargs_enabled' must be defined in the sytem file in the following manner large_ncargs_enabled 1
2. A new kernel must be built (using this system file) and the system rebooted.

To return to the default environment size, the new tunable needs to be either removed from the system file, or its value set to zero. A new kernel should then be built(using the modified system file) and the machine rebooted.
