Re: how many connection in one tcpip port?

On my Solaris 2.6 box, tcp_conn_req_max_q is set to default 128. I suppose this means at most 128 requests can be queued on a port; the 129th connection will be rejected by the listener. I wonder what happens if you lower this number and increase the listener queuesize from its default 5 so that queuesize is higher than tcp_conn_req_max_q. Probably whichever lower takes effect. Because Oracle listener processes a request so fast, to test this you may need to write a shell script to keep looping and connecting (like tnsping) to the listener.
