Add kernel parameter

[Tonatiuh]

HP-UX PA-RISC 11.11.

How can I add a kernel parameter that currently does not exist?

This "new" parameter is required by Oracle Application Server 10g R1 (9.0.4.0):

tcp_conn_request_max = 2048

Tonatiuh,

The tcp_conn_request_max parameter can only be set using the network tuning command ndd. If you want to set this value manually to 2048 run the following command:
/usr/bin/ndd -set /dev/tcp tcp_conn_request_max 2048

If you want to check the values then run the command:
/usr/bin/ndd -get /dev/tcp tcp_conn_request_max

thanks

Hi,

I agree with the post above as you can not add kernel parameter & this infact is a ndd parameter. Apart from setting these like this manually put a entry in /etc/rc.config.d/nddconf file so that it is set at every reboot as well.

Hi,

the demonstration that Devesh and Devender are right is by

ndd -h tcp_conn_request_max

It explains what this parameter does.
You can set it by ndd commands like other people already posted. It is not a kernel parameter.

HTH.

Best regards,
Fabio

Hi Tonatiuh,

You should make entry in /etc/rc.config.d/nddconf. The file should like as follows.

TRANSPORT_NAME[0]=tcp
NDD_NAME[0]=tcp_conn_request_max
NDD_VALUE[0]=2048
