Terminating an ISC TCP/IP session
Terminating an ISC session that uses TCP/IP is generally the same as terminating an ISC session that uses VTAM®.
You can terminate ISC TCP/IP session in an orderly manner, where work in progress is finished before termination completes, or you can terminate ISC TCP/IP sessions unconditionally, where termination is immediate and work in progress cannot be finished before termination completes.
When sessions terminate abnormally, work in progress usually cannot be finished before termination completes.
