I've got a T2000 running Solaris 10 and I'm running into an issue in which I'm
being asked to set the following UDP tunables vi ndd:
ndd -set /dev/udp udp_xmit_hiwat 65536
ndd -set /dev/udp udp_recv_hiwat 65536
I've found that adding these parameter settings to /etc/system does *NOT*
result in them persisting across reboots:
set udp:udp_xmit_hiwat=65536
set udp:udp_recv_hiwat=65536
This is not surprising as you can see in the udp_impl.h source code:
#define udp_xmit_hiwat udp_param_arr[7].udp_param_value
#define udp_recv_hiwat udp_param_arr[9].udp_param_value
So the 'symbols' do not actually exist. Welcome to the nastiness and
confusion that is ndd :-)
Does anyone have any idea what the "right" way to set these parameters is for
Solaris 10?
I don't have a good answer. I can only suggest you write a script to
execute the necessary ndd hackery before running your application.
