Dear all, Some weeks ago I was busy setting up an ISFC connection between my two z/VMs. Meanwhile I succeeded in this task.
However, I have still some quesions. Maybe I miss some documentation but z/VM connectivity manual is not too specific for my taste. I have established a CTC connection between the systems. This connection has one CTC address on each side used in the ACTIVATE ISLINK. When I look now to the Query ISLINK command, it is mentioned there "duple x links". Can somebody please explain me what duplex links are? Is this simply another ACTIVATE ISLINK with the next higher UA? Another question: Is it necessary to regularily check if the ISLINK is up or is the system trying to reactivate a link? Thank you very much in advance. Florian
