Hi list,
I see the following error msg in my drools log but I don't know how to
interpret this.
Do I have a serious problem here?
Has anybody a clue?
Thanks in advance.

You likely have configured a DebugAgendaEventListener, which logs agenda
events (rules activated, fired, etc..)
on the standard error rather than the standard output. If you want a
different behavior, remove the listener
and implement one of your own.
These are not errors anyway.

Hi Davide,
thank you for the fast response. I've defined an DebugAgendaEventListener
as it's described here:

The reason why I've activated the logging was that some rules are not fired
after inserting a special
amount of facts - in my case exactly 20.
Some more details here:
I work on an Event Correlation & Analysis OSS solution that's based on
Grails & Drools 5.5.0-Final.
I'm using a stateful knowledge session and only call dispose() when the app
is stopped - but all facts
are retracted. The functional testing works fine but as I've mentioned it
before when I run the integration
testing it fails, because rules are not fired ('ClearAlertRule' is not
fired) when I insert more than 20 facts.
I saw the errors in the drools log but I didn't know if they were relevant
for my problem here.
I've attached two picts which document the right and the wrong behavior of
the rule processing
- also I've listed the rules of my rulebase.
Has anybody an idea?

The "after 20 facts or so" makes me think that some constraint behaves
differently when jitted
(constraints are jitted lazily, to go from interpreted to compiled mode,
only when they are used
often enough).
In fact, there was a bug that was fixed a few days ago regarding a
different behavior of "contains".
The interpreted version would work as String.contains, while the
compiled version would work
as Collection.contains - or vice versa, I don't remember right now.
Unfortunately, the fix can't be backported to 5.5.0.Final.
Can you try to rewrite constraints like :
_name:catalog['name'] not contains 'Timer'
into
_name:catalog['name'], ! ((String) catalog['name']).contains(
'Timer' )
and see if the situation improves?
On a totally unrelated topic...
I have also noticed that you have a very peculiar data model..
we developed traits in 5.6 and 6.x to deal with relational models like
yours..
would you be interested in doing some research and see if/how they
impact performance and rule authoring?

You likely have configured a DebugAgendaEventListener, which
logs agenda events (rules activated, fired, etc..)
on the standard error rather than the standard output. If you
want a different behavior, remove the listener
and implement one of your own.
These are not errors anyway.

I'll rewrite the rule and give you feedback tomorrow.
"would you be interested in doing some research and see if/how they
impact performance and rule authoring?" - No problem. It would be a
pleasure for me to help.

The "after 20 facts or so" makes me think that some
constraint behaves
differently when jitted
(constraints are jitted lazily, to go from interpreted to compiled mode,
only when they are used
often enough).
In fact, there was a bug that was fixed a few days ago regarding a
different behavior of "contains".
The interpreted version would work as String.contains, while the compiled
version would work
as Collection.contains - or vice versa, I don't remember right now.
Unfortunately, the fix can't be backported to 5.5.0.Final.
Can you try to rewrite constraints like :
_name:catalog['name'] not contains 'Timer'
into
_name:catalog['name'], ! ((String) catalog['name']).contains(
'Timer' )
and see if the situation improves?
On a totally unrelated topic...
I have also noticed that you have a very peculiar data model..
we developed traits in 5.6 and 6.x to deal with relational models like
yours..
would you be interested in doing some research and see if/how they
impact performance and rule authoring?

I work on an Event Correlation & Analysis OSS solution that's based on
Grails & Drools 5.5.0-Final.
I'm using a stateful knowledge session and only call dispose() when the
app is stopped - but all facts
are retracted. The functional testing works fine but as I've mentioned it
before when I run the integration
testing it fails, because rules are not fired ('ClearAlertRule' is not
fired) when I insert more than 20 facts.
I saw the errors in the drools log but I didn't know if they were relevant
for my problem here.
I've attached two picts which document the right and the wrong behavior
of the rule processing
- also I've listed the rules of my rulebase.
Has anybody an idea?

Hi Davide,
good news, the workaround works - ClearAlertRule / _name:catalog['name'],
((String) catalog['name']).contains( 'Info' )
I tried to understand the concepts of traits (
http://planet.jboss.org/post/new_feature_spotlight_traits_part_1)
but I'm not sure if I really got it ;)
What I'm trying to achive...
===
What I try to do is to store the working memory - that's not really correct
in my case because I don't really
store any facts in the working memory - all facts are rectracted. I store
all facts ('Event' & 'Alerts' ) as GORM Objects
directly into the database. Maybe that's the reason why you think that it
is a very peculiar data model ;)
Lucas Amador described in his book 'Drools Developer's Cookbook' how to use
persistence to store knowledge.
I've tried this but it didn't fit my needs here because 'Alerts' are not
only modified by rules they are also
modified by human interventions (admins/operators) - therefore all facts
('Alerts') must be displayed in a console.
Sometimes a picture is worth than thousand words therefore please take a
look at the following blog post, so it's
probably easier to understand what I'm trying to achive.
http://rapideca.blogspot.de/2014/02/lets-turn-vision-into-reality.html
Maybe there is a much better approach to get the job done - all kind of
help is appreciated!
