Kernel paramter in zone

Question

Hi ,
I have a issue I need to change a kernel paramter in a zone
we have
global Zone
>>zone1 full zone
>> Zone 2 sparse zone
Now I need to change 2 parameters in both the zones full and sparse
tcp_conn_req_max_q
tcp_conn_req_max_q0
Can Gurus please tell me how to do it for both types of zone.I can not find anything like /etc/system in zone1.
for zone2 i suppose if I change paramter in global Zone it would be reflected in Zone2 (sparse Zone.)
BR,

See the Solaris Tunable Parmeters Reference Manual for them. It describes the individual parameters and the fact that you can use 'ndd' to make changes.

for zone2 i suppose if I change paramter in global Zone it would be reflected in Zone2 (sparse Zone.)Sparse vs Full isn't something that affects how the portions of the OS are shared or separated here.
