Hi again Wim

We where thinking in putting the mirrored libraries of the production machine into a separate storage group in order to avoid accidental object manipulations by the developers. As we understood, if the library is not in the namespace of the job than it cannot be referenced without intent. And that this can be achieved by implementing IASP.

This is true. If you are happy that the programmers won't touch your data except unintentionally then this will possibly work. I had taken your statement to mean you want to prevent them from touching the data. Remember that one command (SETASPGRP) allows them to swap from a development namespace into a production namespace; If they have access to a command line they can run this command at any time, although I guess you could secure it :)

If they do support calls and regularly swap between environments as opposed to using an alternative sign-on there are bound to be accidents.

At this stage I have to confess to preferring to keep developers doing development away from production so I may have read more into your desire to separate the environments than you intended.

I still think on balance you will get more mileage and more value out of a separate machine than the added administration an IASP will probably cost you, but what the hey, it's fun to play with, that's for sure :)

What access does *PUBLIC have to your data have at the moment ?

I'm willing to bet that it is more than you want the programmers to have.

Okay, how much!! (sound of rattling keyboard)

OK, if *PUBLIC is *EXCLUDE you win :)
