True: we are searching for what drive the lost session disconnect. But I would not limit my search to the host. Network appliances/firewalls can be configured to do things like this.
What does not fit in this scenario is that other TN3270 clients are not having the problem. That would point back to QWS as being the unique factor in the equation. That said, we cannot assume that all are following the same network path (and thus chain of network appliances/firewalls). Another thought: Have you tried connecting directly to the host and bypassing the session manager? -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Thompson, Steve Sent: Thursday, June 18, 2009 11:13 AM To: [email protected] Subject: Re: TCP Settings for KeepAlive -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Hal Merritt Sent: Thursday, June 18, 2009 10:20 AM To: [email protected] Subject: Re: TCP Settings for KeepAlive Hmmm.. almost sounds like QWS3270 may be getting impatient when waiting for a reply. That is, the 'keep alive' time may apply only to an idle session as opposed to a wait for reply situation. I'd look into QWS3270 parameters. <SNIP> QWS3270 is the one getting notified that the connection has dropped. In discussions with Jolly Giant, they will wait forever for the host to respond. Meanwhile, they will continue, at the prescribed intervals, to send the keepalive. Something, somehow is deciding on the host side to terminate the connection. And I just can't seem to find it.
