Abstract: PROBLEM TO BE SOLVED: To provide a propriety inspection for re-initialized CTC connection between a first channel and a second channel in a computing environment where a channel-to-channel control unit function can be provided within either one channel after the initialization of channel-to-channel connection and moved from the one channel to the other channel after the re-initialization of connection. SOLUTION: After initialization, a newly formated CDR having a device NED and specified NEQ is stored. After re-initialization, an existing CDR having the same format is acquired. When the stored values of one set of NED and NEQ are matched to the existing value in an optional order, the propriety of the re-initialized CTC connection is inspected. COPYRIGHT: (C)2004,JPO

Abstract: Channel-to-channel communications is provided by integrating channel-to-channel functionality into one or more communication channels of a computing environment which may include heterogenous computer systems. The one or more channels having the integrated CTC function are non-dedicated channels also capable of conventional channel functionality. Work units at such channels are forwarded to either the CTC function or the channel function based on work unit type. Further, a facility is provided for automatically deciding which of the first channel and the second channel is to provide the CTC function for a CTC connection. Partition-to-partition communication can also be accomplished using the integrated CTC function by establishing an internal logical path between a first logical partition and the CTC function and a second logical path between a second logical partition and the CTC function.

Abstract: Communication method between partitions in a computer environment prepares a CTC-channel function having at least two logic partitions and then generating an internal logic path between a first partition and the CTC-function, and an external logic path between a second logic partition and the CTC-function, the two partitions communicating with one another via the CTC-function and a single channel path of the computer environment.
