Hi,
Would like to use GlobalArea enumeration - 'Member.title': ['Mr.',
'Miss']
in my custom package rule. Am trying to access it in DSL rule (as we want
guided editor to use enum), like {title:ENUM:Member.title}
If I create above enum in custom package, am able to do it cleanly.
Also
AFAIK, you still need to import the asset from the Global Aarea into your
package.
Think of it like creating a symlink\shortcut between the Global Area and
your package - changes to the asset in the Global Area will be visible in
your package.
Assets in the Global Area are not automatically
Thank you. This was really helpful.

Hi,
I was wondering which is the proper way to do sanity checks (not null
etc...) on a fact before starting the actual business rules.
I have created a a ruleflow with a validation node (VALRFG) and a business
rule node (BRRFG) to determine execution order.
If in the validation node a not null
Thanks for the reply. Actually I was trying to work it out the REST API way,
I used for my other purpose.
I understand that Global area wont be accessible directly, but couldnt find
related content on net.
Since I am a beginner to drools, am still working on importing the assets
from Global
Hi,
I am not much of an expert on Drools. I got a DRL file (very small rule set
of less than 10 rules, that checks few conditions, also includes DB calls).
I use Drools 5.2 inside a grails application. I am using stateful session. I
call this rules 100,000 times for each for each of the 100,000
Hi,
Are there any instructions on how to enable JMX Beans and monitor Drools
using JConsole or JVisualVM anywhere?
Thanks,
Abdul

There are a couple different options available.
I haven't tried it but some of what you are trying to do sounds suspiciously
like what you are trying to do is a workfow process or rules plan. Which
might mean you want to look at planner or consider how you are approaching
the problem.

I assume you are calling dispose() after using each session? Using
stateless session is an option as well.
If so, with Drools 5.2 we had a problem with jbpm being in the classpath,
fixed in 5.3. Did you tried Drools 5.3 yet?
To enable MBeans, just use the MBeansOption.ENABLED in the
Hi Edson,
Yes I am calling displose().
No I have not tried 5.3 it, I will give it a shot. What was the issue with
jbpm being in the class path, is it related to memory leak over time?
AS for MBeans, thanks, I will try that also.
What I am doing now is removed all rules, putting one rule at a
Is is possible to get textual rule content from
org.drools.definition.rule.Rule? What I am looking to do is get the rule

AfterActivationFiredEvent)

If you can get the name from the AfterActivationFiredEvent, you can search
in the DRL file for that content right? I don't know if there is a way to
get the content from the knowledge base, because as far as I know the
knowledge base don't save the DRL file inside it, it just get the LHS of the
No problem Sumeet,
Feel free to open new threads if you have more questions, I'm really
passionate about these topics so I'm always open to discussions.

Are you using persistence? can you give us more context about what are you
trying to achieve?

Sorry Lisa, I should have remembered you don't use Guvnor. I assume all
rules compile ok without use of a change-set? Is it possible to put together
a test case and open a JIRA? This sounds like something new.

I wish the Rule definition gave more detail than just a rule name, package
name and metadata, or there was some way through the KBase api to get to
it. Seems like I will need the to fetch the rule content from guvnor via
REST (via some sort of timestamp versioning of my own)

I'm a relatively new user to Flows, but I have worked with a colleague to
instantiate flows that control a sequence of rule sets being applied to a
set of data in a meaningful order (e.g. I do pruning to limit the set of
facts as a first step, then generate sets of hypotheses, then score the

This is because I use log:
KnowledgeRuntimeLogger logger =
KnowledgeRuntimeLoggerFactory.newFileLogger(session, test);

But if i use stateless session, it will not print any log.
my code is like this
HI,
There was one bad rule, when I removed that memory leak is gone and the
performance improved drastically!!! (from 60 sec for 1000 records to 10
seconds, satisfies our requirements) I am not sure what is wrong with the
rule, I will check that tomorrow, I am a happy man now.
