Conceptually I could agree with you. But the way it's done is in my view
good. Let me explain why:

1- Everything is thought to be self "cleaning". This isn't going to store
stuff indefinitely
2- You have the option to put it into a specific dbspace and you should do
it.
3- Putting it into an external datasource would raise the problem of inter
instance dependency, which would be hell
4- You can (and you should) collect it and store it in a central place
5- Having it running on the system means you can always collect it as long
as the system is running (nothing to collect is it's down). So you can stop
the central repository every time you need and you won't miss anything

So, I like it like it is... The things I miss can be solved... Hopefully I'm
in the process of doing it.
My perspective of OAT and the dbscheduler changed.... I have to be honest
and a few months ago I didn't like it....
After some presentations in IIUG conference and also after a customer
insisted on me, I tool the time to study it and now I feel it's one of the
best things in IDS 11.

It doesn't mean I like everything about it... But it really gives you a
great infra-structure to build on. I just would love to see much more tasks
already supplied in the engine.

I already blogged about this, but for me, dbscheduler + OAT + alarmprogram
is a great way to monitor your servers without nothing more...

What it does not provide is a global alert view (currently OAT's view is
only for the instance you connect to)...
I will create one, but I'm not fully confident it will work as well as other
solutions.

As for the custom scripts solutions.... It's better to take that knowledge
and build OAT tasks. Easier to setup, will not depend on CRON etc.

Regards.
