RE: Test Development System Survey

["Jones, John (US)" <John.Jones@xxxxxxxxxxxxxxxxxxxxxxx>]

At both my current and a former employer, we started with everything on
the same system but migrated to having dev on a separate box than prod.

What we currently do is run dev on our business continuity system.
Which means we've an 830 that rarely sees more than 5 concurrent users.
^_^  In a BC situation, we can have the developers work odd hours or
just halt development work temporarily if what they're doing would
impact production.

If you don't maintain your own BC environment and you think the
developer workload is impacting production, I'd recommend LPARing your
main system to give the developers a slice of the system that won't
interfere with production workloads.

It should also be pointed out that many times developers have a fair
number of priviledges on the system and that without a pretty tight
security model, they could have access to production data.  Which could
be a problem during an audit.  Our developers have *USER/nothing special
on the production box since they use an app for time entry but otherwise
they cannot do anything on the production system.

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)? _______________________________________________
