Capacity or Limitation on the TCP/IP port in HP UX 10.20

[M.V.Yuvaraj]

Is there any constraint on the TCP/IP ports. How many loggin sessions can we make using the TCP/IP connection.

if you mean telnet session , it is kernel parameter npty.

I presume you are talking about tcp socket connections, if so under HP-UX 11 there is a parameter;

ndd -h tcp_conn_request_max

tcp_conn_request_max:
Maximum number of outstanding inbound connection requests. [1, - ] Default: 20 connections

I cant find an equivalent using nettune (instead of ndd) on 10.20 but I have no reason to suspect it is different or higher than 20. Note this is 20 inbound requests (outstanding - so unfulfilled by the destination application [eg. oracle[), not number of active connections. So basically if your application cant keep up with the amount of requests coming in and over 20 requests get backlogged up then some may be dropped. I guess there wouldnt be a maximum number of socket connections - as long as the server can keep up fulfilling them then more can come in.
