1. The orderly deactivation of ACF/VTAM and its domain. An orderly closedown does not complete until all application programs have closed their ACBs. Until then, RPLbased operations continue; however, no new sessions can be established and no new ACBs can be opened.; IBM的通信系統(tǒng)軟件ACF/VTAM及其作用區(qū)域的有序撤銷。只有在所有的應用程序已 關閉其存取控制塊(ACB)后,才完成有序關閉。在這以前,基于請求參數(shù)表的操作仍然繼續(xù), 但不能建立新的話路,也不能打開新的ACB。參閱cancel closedown, quick closedown。 2. The stopping of the system in such a way that ensures an orderly restart and no destruction of messages. When a system is forced to stop, an orderly closedown provides that all records are updated that should be updated and that no records are erroneously updated again when the restart is made. Furthermore all incoming and outgoing transmissions are completed, with a message sent to the terminals which notifies the operators of the closedown. | 一種系統(tǒng)關閉的方式,以這樣的方式關閉能夠保證有序的重啟動,并保證不破壞信息。當 系統(tǒng)被強制停機時,有序關閉保證應該更新的記錄均能更新,而且在系統(tǒng)重新啟動時不會錯誤地 重新更新。此外,它將完成所有正在進行的傳輸,并向終端發(fā)出信息,通知操作員將關閉系統(tǒng)。
