Thank you guys.
After much ado about it, Casper Dik and a few others pointed out that the
variable is not accessible from /etc/system.
I also found that not all tcp module parameters are accessible from
/etc/system.
The reason I prefered /etc/system solution is to have all the driver
configurations consolidated to one place. Also to make the change effective
as early in the boot sequence as possible. The latter did not apply to this
particular parameter since the change does not impact the system behavior
immediately. However, I was putting hme parameters and such in /etc/system
so that I can make a sweeping change.
One more note, there is now a comprehensive document from Sun called
"Solrais Tunable Parameters Reference Manual" published lately, which lists
and describes what can be done in /etc/system. I found that
tcp_keepalive_interval was not one of them.
