Hi all,
i'm a newbie on Drools and want to understand the general architecture of
the solution.
Is it true that Drools Guvnor helps managing rules definition but it is not
a rule server ? Meaning we can define, update, archive, test... rules but
not execute them in Guvnor?
My understanding is that Drools expert is the engine, let's say the rules
server) on which one rules are executed. Is there any graphical tool to
manage this engine? I mean to add/remove rules, access a dashboard... Is it
drools-server.war?
Is there any pre installed runtime environment with the engine and - if
there is one - the management console?
I tried drools-install.zip with ant install.demo but it doesn't work for
me...
Thanks a lot for your feedback, I'm waiting to test it!

A few months ago a question was asked about the difference and the use case
involving Drools Expert and Drools Guvnor.
To be honest, it isn't clear for me too and as there wasn't any answer to
this first question, so I'm trying to have an answer with your help :)
What's clear :
- Guvnor is a repository for the assets
- The easiest (?) and certainly the mainly available as a tutorial solution
is to create in each application an agent that grabs the assets and execute
the whole thing in its own context.
What's not clear :
- how to centralize the execution in order to know exactly what's executed,
by whom, and how (be able to log which facts are sent, to which rules, and
be able to read the execution plan
- if it exists a "real" stand alone centralized engine that match this need
(Drools Expert ?)
If some can explain this a little bit more, I'll be really happy to read !
And if it can be added to the current documentation, it could be a great
idea too.
Thanks for your help.

know too much about it.
With kind regards,

I think that's fair. We don't have centralised management of expert
runtime's yet. It's currently de-coupled via a pull mechanism.
