Don't forget the table_prefix - current default is "nagios_" but I don't 
know if this will change (I think it's a rather useless prefix unless 
you have more different "collectors").
Naturally it's better taking "telling names" for tables, variables, and 
so on. But everyone who has to program the source will hate it, so 
shorter names with table description are more useful imho.

Yep I know what you are saying and if anyone over here would allow me to 
do it I would. But my current task was/is maintaining the NDOUtils 
Oracle and optimizing it (too much DB entries, housekeeper f*cked up, 
only needed current states, no history) and after all finding a way to 
merge the work done by David Schmidt into the NDOUtils master.
Looking at the ongoing process of kicking the NDO and using something 
new doesn't really fit to my plans. But anyway currently Icinga fits the 
most for our concerns because there are no ressources available to 
create a new NDO or similar (I'd be happy only having this project and 
nothing else like coding DNS tools ;-)

I will share my knowledge meanwhile in Icinga GIT (when DB schema is 
defined, and the code can be merged and optimized) for testing. So far 
it is all the same with libdbi. A first howto on the libdbi driver for 
Oracle can be found here - kind of tricky:

https://dev.icinga.org/issues/show/108

Some code optimzations for IDO have already been applied by Hendrik 
(driver loaded successfully, fixed segfaulting and so on) so the 
debugging is getting easier.

And even if I have to modify the libdbi itsself for the usage of 
parameter bindings (which is heavily used for Oracle e.g.) Merlin could 
also profit from that...

Kind Regards,
Michael
