service port limit

[jack Hu_1]

Dear Sir:
I want to know is there any service port limit ?
I have a TIBCO RV services
on both 10.20 or 11.0 OS.
But I found that if more than 200 or so connection , I can't add any more connection on it.
Is there any where I can modify ? kernel ? or It's the limitation?
thanks
Jack

I guest you mean telnet.In kernel there are paremeter npty.I guest the telnet connection must less than npty.Else you need to increase this.

Please advise actual error message.

Malay Boy could be correct about adding additional pseudo tty's

The telnet is fine.
I say some port like Oracle used.Or just like the rv services port 7500.
If there is more than 200 connection,the next one can't connect to the server.
thanks

Sounds to me like you want to tune your tcp/ip parameters. Specifically, tuning the tcp_conn_request_max and related parameters will probably help you.

Please review this excellent tuning guide. It's based on Solaris, but almost everything applies to HP-UX as well.
