Hi, John, You hit on what my thoughts are behind all of this. We had so many layers of contributing factors and this may be the last one, and it will be difficult to prove now that so many other things have been fixed and users are not being dropped as often.
I want to remove any chance of a dropped TIMEMARK handshake from killing a legitimate session that a user in deep thought on. A 15 minute cycle to try to kill a session relying on software sending packets that threaten "Answer me or Die!" across goodness knows how many hops across the planet through multiple firewalls with floods of traffic seems too short. I'd rather wait a time longer than the JWT setting to try to kill the session to clean up an LU. I'd rather let MVS do the session killing legitimately and not rely on network handshaking across the internet. Again, any thoughts?

We do and always have. However the way TIMEMARK should work is that if the session seems to be idle because of no activity on the users part, the TN3270 server is supposed to send out a "Hey are you there?" message. If the client responds, then it is marked as active. If it does not respond, it is considered "gone" on the next SCANINTERVAL and the connection will be dropped. So, if there is a firewall configured to prevent the either they "Hey are you there?" messages or the response from coming back, they will get disconnected. I could be something other than a firewall, anything that could filter traffic. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
