Alas, yesterday was my 30th birthday. If I were nearly ready for retirement it would make this pending (potential) outsourcing that I am facing much easier to take. As it is, if it does happen, I'm probably going to have to go back to working on UNIX systems and forget about z/VM, as I will have just barely over two years experience at that point. I think that will be the biggest disappointment of the whole ordeal, for me personally. The anthropology of technology is a sort of hobby of mine. > I was thinking though, back to when VTAM was new and folk > were naming terminals.

For a huge deployment of equipment which is all essentially functionally undifferentiated (or at least interchangeable), there's a lot to like about that approach. > Names based on location and function have their good points. True. In my experience, however, machines change location or function more frequently than they change names. This is probably more true of distributed systems than it is of mainframe systems. > I note that for some years (but no longer) there were > half-a-dozen or so IP addresses associated with www.ibm.com. I suspect that it is no longer true, not because redundancy and load-balancing such a setup would have afforded is no longer required, but because there are more sophisticated ways of doing it these days than just with multiple DNS A (or CNAME) records. F5 Networks, for example, have done some rather astonishing things with their BigIP product---which honestly has probably moved on to accomplish even more astonishing things since the last time I looked at it four or five years ago. ok r. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
