Munif, maybe my original comments didn't make through the world of email servers.
I don't think I've ever seen one doc that list all the things that can use CTCs. At our shop the real users of CTCs devices are XCF and VTAM. Those are the only tasks that have CTC device addresses defined to them. In a sysplex (base or parallel) things like GRS (and others) can use XCF for communications so they don't need to have any CTC devices defined to them. They let XCF handle the message traffic. If you don't have any of your lpars in a sysplex then you can't use XCF so for like GRS you would have to define some CTC devices to GRS. Tasks like JES2 or CICS can use IP (OSAs or Hipersockets) or VTAM/SNA for communications. Thanks..

I think that's largely because there is no single doc that lays out all application uses of (F)CTC any more than doc that lays out all application uses of DASD or tape. . .

My basic question still remains the same..where all CTC(FCTC) can be used under zOS and all required configurations. Do agree HCD/IOCP is very well documented but not the applications, VTAM, IP configurations. regards Munif ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- Please note: This message originated outside your organization.
