Re: Test Development System Survey

We have 2 main boxes-- one is all live, the other split live/test.

First, you need to have separate libraries for data, programs, and source code. If you haven't done it, do it! (:

The next biggest thing is setting up security so that production libraries are not usable by programmers! We feel that authority should allow programmers to -read- live data, -use- live programs, and -read- live source. This means that all a programmer needs to test is a library where copies of the production files can live. A little juggling of the library list gives complete isolation from production:

LIVE ENVIRONMENT:

        DATALIVE
        PROGRAMLIVE
        ...

TEST ENVIRONMENT:

        DATATEST
        PROGRAMTEST
        PROGRAMLIVE
        ...

This means that the PROGRAMTEST library only needs the new objects being developed or changed. Existing objects in PROGRAMLIVE are used just as if it were a production environment.

This also works for library lists in job descriptions. Means you can test batch jobs without affecting production data!

We include output queues in our DATALIVE/DATATEST libraries (well, not all of them-- QUSRSYS has a bunch of output queues). Including them in the DATAxxx libraries means we can use production names, and not have test orders going to the warehouse for picking. (:

We are currently using our AS400 production box for development as well (the
test/production systems are separated by logins/environment variables). How
many of you all also combine both on one machine, and has this caused
performance problems for you? Or do you use a test machine for development
specifically because of this (or wish you had one)?
