Hi Martim,
I would say, that this is pretty simple ;-))
You do need the iSeries Navigator in the "full version", not the one, that gets installed, when you leave all checksmarks as they are. Then you can handle all the OS & DB related stuff pretty good ;-)
and:
the DB doesn't need much maintenance, as it maintains typically itseld - so there are a few parameters only. (e.g. QAQQINI)
