Hal If you had been following the concurrent thread entitled in one manifestation "FW: Mainframe console issue - urgent", you would have read that I referred to a provision in the customisation of ICC consoles which perhaps precisely meets your requirements. I originally proposed this option on the VSE-L list, a number of subscribers tried it out and the feedback was positive and encouraging.
I have - almost[1] - no experience of ICC consoles but, having been duped by the VSE-L thread into supposing VTAM may be involved, I - shock, horror!!! - took the almost unprecedented step of taking a peek at the ICC manuals[2] in order to try to address the issue raised. The function, you may like to try is to specify "Defer Host Disconnect" with an infinite "deferment"[3]. That way, as I believe it works. if you have connected once from a TN3270E client, the TN3270E server pretends that the ICC so- called "session" is permanently connected whether or not an actual TN3270E connection exists. Is this what you want? Incidentally, I was not aware that, say, MVS consoles were ever anything other than channel-attached - which is still logically the case with these TN3270E server implementations - until the SNA option appeared - of which I have no experience but I believe is unlikely, on the basis of the when the respective functions were available, ever to have involved consoles with BSC 3270 connections - whatever the technology of the medium. Chris Mason [1] I've visited a pod of operators where I was assured such consoles were in use. [2] There are not so many and, for IBM manuals, they are "light" reading extending to 66 pages for the "regular" manual, SA22-7990-01, but 300 pages for the redbook, SG24-5948-05.
