@ Nikhil,
I am not sure weather it a good practice to seralize a package and store it
, i am new to it and i am storing the drl files in db .
Can we retrive our DRL file after retriving the packge from database.??

Exactly! That's precisely why i'm trying to find a workaround. I have no way
to activate a specific set of rules except for stacking up activations using
agenda-groups.
Any other suggestions?
Thank you.

Hi,
First of all, thank you both for your answers.
@mauricio:
I'm currently not using drools flow, only expert, so i'm not very familiar
with the approach you suggested. Isn't it possible to achieve this goal just
by using drools expert?
@Wolfgang:
My problem is that i cannot have the different
if you use the new api's (5.x StatefulKnowledgeSession instead of
workingMemory) you don't have that methods exposed.

You could manually activate and deactivate ruleflow groups using
workingMemory.getAgenda().[de]activateRuleflowGroup(name).
workingMemory.getAgenda().[de]activateRuleflowGroup(name).
session.fireAllRules();

It can handle it. The limiting factor is available heap.

Hi,
I have compiled some rules and added it in packages. Then I
serialized those packages and stored in database in the form of CLOB data
Now I am able to get Packages back from database and loaded it in RuleBase.
But while executing Rule, I am getting the following Exception.

Hello there,
I was able to draw an "Incident on Workstation Process" using Drools flow

Hi Thomas,
You are correct in your interpretation of what I want to do.

Hi Wolfgang,
Sorry for the late reply on this.
Actually I did miss your earlier reply.

exceptions) to 300MB.

I saw that you change the transaction-type to RESOURCE_LOCAL, and not JTA as
it's in the documentation.
In the documentation I think that it mention that drools requires JTA, for
it's internal mechanisms, that's why we use bitronix as a transaction
manager implementation.

Hi Mauricio, team
I mapped my javabean in the persistence.xml
org.acme.drools.Account
And after run my main test I can see the "account table" in DB, but it's still
empty, probably I am missing something in the project configuration.
Let me check and I'll reply back
Tks!

I've been using agenda groups without any trouble for a similar problem, doing

repeatedly.
You don't have to be afraid of the focus stack growing indefinitely:You control
the "push" (setFocus()), and if an agenda group's activ
Hi miguel,
Did you try creating a new Drools Flow process with Rule Tasks inside it to
isolate each specific set of rules.
Then you can insert the facts into the working memory, start the process and
the rules will be executed secuencially.
You need to remember also that, if the rules are activated
Anatoly, if you can share your generic implementation that would be nice..
because a lot of people is looking for something like that.
I prefer custom and domain specific implementation, but it seams that a lot
of people is looking for something generic that can be reused.

I'm having some trouble implementing the desired workflow of rule firing in an

Actually, this kind of error isn't discovered by the Drools DRL compiler; it
would be flagged by the Java compiler. (You can verify: if you make the same
error in Java code, you'll get that error message.)
But if you are using dialect "mvel" (are you?), this is not flagged as an
error, and it woul

The subject says it all really: is there any way of determining the

Any help would be very much appreciated.

Hi all,
I know there are some basic ways to chain rules together, by setting flags
in consequences that are checked in the conditions of other rules...
but in a large system based on rule templates, where thousands of rules are
