It is documented in the RSCS Planning and Installation manual although the option is KEEPALIV= (not keepalive) and the default is yes. So RSCS would have enabled keepalive for the socket session, that would probably be what is happening. >From the other threads, if JES has defined an ITO= parameter, I would think they would have sent a signoff record when the link went down, not just leave the link in a 'gone' state. I bet something else is taking the link away. Is the JES side aware of the link state? Best Regards, Les Geer IBM z/VM and Linux Development
