Bob, I think what it means is that you will only "suffer" .3 seconds of application outage in a year. Of course that means you have a fully redundant SYSPLEX set up with duplicated everything such that when you do have to bring down a CEC, the application workload is pushed to a different node and keeps running.

I'm just getting around to reading the article someone cited here: https://urldefense.com/v3/__https://www.linkedin.com/pulse/results-mainframe-application-modernization-migration-ross-mauri/__;!!KjMRP1Ixj6eLE0Fj!vRWugZ9PZChjYOSRHES5hJagG3oL3-Aj5C29vq6Z4IH31v7-TLc3h60QpKT33OATN9JvjoIKMLQgPjtpjd4O2yQ$ I heard that "8 9s" claim go by before, but I didn't pay much attention. But in the article it says that equates to 0.3 sec of downtime per year, and I pause. Does "down time" not include IPL, then? When you IPL, doesn't that count as "down"? Because if it doesn't, I don't see what use that measure is. Or does no one IPL any more? --- Bob Bridges, [email protected], cell 336 382-7313 /* Even the most marginal NBA player is an absurdly better athlete than an ordinary person.
