IIRC, the >3344s on ACP actually used "software duplexing" for reliability. My favorite TPF story, from Sabre, circa 1988: Someone started a TPF transaction without proper testing, and it clipped something like 1,000 packs. MVS and TPF were quite unhappy about it. While the MVS and TPF guys were moaning, Mike Roegner (now retired) quietly went over to the VM system and wrote a small Rexx program to attach, ICKDSF (or whatever the equivalent was-this would have been pre-XA, and I forget!), and detach, and started relabeling the packs. Meanwhile, they were down for several hours, at a reported cost of $20,000/minute. And of course neither Mike nor VM got the credit they deserved for saving the day. The outage did make ComputerWorld, however. (Of course it did-would ComputerWorld ever forego the opportunity to run a negative story?) .phsiii ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
