Session outages (server)

Session outages are reported as an unexpected termination of the TCP/IP connection or the Telnet-to-host application session. A session that has been disconnected or terminated results in the client being returned to the panel where the initial TELNET command was entered and message EZZ6034I is issued. See z/OS Communications Server: IP Messages Volume 4 (EZZ, SNM).

Telnet sessions can be terminated due to TELNETPARMS specified in the PROFILE data set. Telnet ends a session if there is no activity on the SNA side of the connection for the amount of time specified in the INACTIVE parameter. Telnet checks for dormant sessions on the IP side of the connection using the SCANINTERVAL/TIMEMARK parameters specified. When appropriate, the connection is terminated due to this processing. See the SCANINTERVAL/TIMEMARK parameters in z/OS Communications Server: IP Configuration Reference for additional information.
