Have you looked at "extends" keyword? You could use a base rule and
extend it for ruleflows. Not positive it would work for your needs,
but possibly.

Probably not, work is done on insert not fire. Fire just shows what is

buttons. Not a big deal, but it isn't automated. You can then use that DRL as a
resource in your application. I know there was some working being done to be
able to pull out DRLs from Guvnor using xml calls, but don't know if that was
ever completed.

The category rule should just extend all child rules in that category.
If all is working your generated DRL should have "extends" in the
"tax" (etc) rules.

You won't need much horsepower. If anything I would go 64 bit and put
6-8 gigs of ram in the box. CPU won't matter much.
We run 10k rules on an old dual core, but the rulebase takes 2.5 gigs
of ram.

I don't believe so. This is something we need as well and will likely be
contributing soon. If this were to be added as a patch do you have a preference
as to how it would work? On save, call a url with the rule name? What are your
needs for this?

I'll say it before someone else...
Evals are the devil, avoid them. From memory, the newer drools handles old
rules poorly, using extensive use of evals. It's the reason we have not
moved up to the newest version yet. It's probably not pretty but you may
have to rewrite/reconfigure your rules to a
I'm not sure your use case, but I will answer what I think you are asking.
We had the need of turning on/off rules per time the rules were fired. So
different data may need different rules to fire, and simply too dynamic to
build rules around. It is as simple as a manager may choose to override a

We handled this by dating all rules with a production start/stop date.
Effectively we made all rules have a date condition implicitly added to
control situations like this. I believe the BRMS has this functionality in
it as well.

You would likely NOT want to create a rulebase per session. Most people
create working memory per session. Rulebases should only be loaded once
per server (context) in my opinion, and you reload it as rules changes.
Loading a rulebase loads rules from a file, and orders your rete tree. For

Couple questions about the JBRMS persistence layer. I have been trying to
figure out how to upgrade and incorporate the new 4.03 code into my
current app using 2.x and 3.x drools. After many months of off and on
playing with 4.x I want to see if I have some things straight.

I have a question related to this. Is there a way within a rule that you
can add 30 days to a date...
//mydate within last 30 days
mydate + 30 > getdate()
then dosomething()
I would only want mydate modified for this rule only not re-asserted on
the stack with a new date. Also if someone could
Wonderful idea. D-rules or some variant is much better than the previous

Telling an exec we saved a lot of time & money using this system called

Store all rules with a unique id (rule id) and keep dates of when rules
were put in/out of production. Store your net matches in a database,
after a run, and you can easily pull the delta to show what didn't
"match" on a particular day.

Yes something like that should work fine. I'm not to up on the
"synchronized" call you're making but if you can access some app scoped
memory, what you have will work fine. I might suggest you try and cache
the rulebases [call execute(String ruleFile, Object [] objects)] well
before you expect
Typically you would want to create a rulebase at server load or at the
application scope and store that rulebase as a singleton. Then at runtime
get a workingmemory, assert your objects and fire rules.
For our application loading rules into a rulebase takes from 10 to 180
seconds , but working
