Thanks for your answers, it really does the trick and I need to agree to Tom for his reasoning, why I want to do something like this. To add something to this, having Oracle, Postgres and AOLserver runnning at the same time consumes quite a bit of memory (around 300MB on my system). If I want to work on other stuff, it has some impact on performance, so I want to have a way to shut it down and start it up again, whenever I need to.
