on OpenVMS 7.3-1 with TCP/IP 5.3 Eco2 I can see many tcpip parameters:
TCPIP>sysconfig -q inet
how can I change these parameters (e.g. tcp_keepidle, tcp_keepcnt, tcp_keepinit) processwide (not systemwide)?
Regards,
Kirsten

Re: Changing TCPIP-parameter
first thank you all for your fast reply. Now my collegue has the following problem. He needs a tcpip-socket with an other idletime than the systemwide idletime. Is this possible?
Regards,
Kirsten

Re: Changing TCPIP-parameter
I simply add the settings to tcpip$etc:sysconfigtab.dat and restart tcpip.

Re: Changing TCPIP-parameter
I can't restart TCPIP, it is a production system. But when I change them with sysconfig -r it is systemwide and this is, what I don't want.

Re: Changing TCPIP-parameter
if you want to set these options for a specific socket, you will have to do some programming !
See the description of the setsockopt() function call in the TCPIP Sockets API and System Services Programming manual:

Re: Changing TCPIP-parameter
I've discussed it with my collegue who needs the solution.
He said, that the API uses the parameter tcp_keepidle and can't be changed.
And here is a short description of his problem. On our VMS machine the socket is in server mode. The clients are mostly windows clients, SPS. Sometimes it happens that somebody cuts a network cable. Now the VMS server waits the tcp_keepidle time until he recognizes that the connection is not longer existing. The problem is, that the tcp_keepidle time on our machines is 2,5 h (not the default 75 seconds) and we can't change it. It would be now great if some processes who don't need this long time can have a shorter time for the timeout.
I hope I could it explain quite good.
Regards,
Kirsten
