摘要:
A method and system are disclosed for generating a data logout in a computing environment having a processor and an input/output subsystem for receiving data from and sending data to the processor. The method comprises the steps of the input/output subsystem maintaining a defined set of data; at defined time, the processor issuing a data logout command; and sending said data logout command to the input/output subsystem. In response to receiving said data logout command, the input/output subsystem sends said defined set of data to a specified location. In a preferred implementation, the input/output subsystem includes a channel subsystem and a plurality of input/output devices, and the data logout command is sent to one of the input/output devices. Also, in the preferred embodiment, the channel subsystem includes a channel control unit function and the data logout command is sent to the channel control unit function.
摘要:
Validation of a re-initialized CTC connection between a first channel and a second channel is provided in a computing environment in which a CTC CU function can be provided in either channel after initialization of the CTC connection and can move from one channel to the other after re-initialization of the connection. After initialization, a newly formatted CDR having a device NED and a specific NEQ is stored. After re-initialization, a current CDR with the same format is obtained. The re-initialized CTC connection is validated if the stored set of NED and NEQ values match the current values, in any order.
