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.
