I said I want to save resources whenever and wherever possible. It's what helps makes our data center efficient and (hopefully) keeps us from being outsourced. Just like any "best practice" - every little bit helps. But to answer your question, IEBCOPY is probably executed thousands of times a day. Some of it part of production jobs but more of it is probably related to change control procedures used to copy modules from production to test and from test environments back up to QA and production. Some things you do just because you know they will help - even if almost impossible to measure. This is something that is certainly measurable. > >IIRC, COPYMOD came out with XA. >We've/I've used it non-stop since then. >It's never been a bottlneck/resource hog. > >The only place it's measurable (that I'm aware of) is during system's maintenance. Did you see my test for just a single library. You don't call a 350% increase in CPU time measurable! >And, I would still do it, then. I've stated a good case not to, but you are certainly free to do what you want and encourage all your users to use COPYMOD 100% of the time.
