[rules-users] Drools Salience and no-loop
So I have setup my drools execution as follows: 1.A single thread is pooling Orders from the db and insert them into X number of sessions(10) running on separate threads(fireUntilHalt()). 2.

There is another set of rules which then check the Order for these preconditions along with others rule sub 1 salience 100 no-loop true when some_conditions main 1 consequences present then modify order info(no update invoked as other rules in the session don't care) end 4. I then have a single rule which has a low salience and should be last rule to fire in the activation which retracts the Order and hands it to a service for post processsing rule END salience -100 no-loop true when ord:Order then retract(ord); invokeService(ord); end The problem I am having is that my END rule is being invoked on certain Orders in working memory before the other activation have taken any affect(I have verified this by send a replicated order 1000 times and each time a large majority his the service before anything was modified on the order).

Re: [rules-users] Duration attritube and Temporal Operators

But it does say you need to set at least the start time and duration. If you don't set the time stamp , it gets a timestamp of the time it was inserting into working memory and duration 0. 3)timestamp is the same as start time. if no duration is set In our rule set , I set a timestamp attribute, duration and also a endtimestamp. You can also do items like this , but reading the docs I am double checking timeEndMs after[-120s,120s] AND0.timeMs , More is in the http://docs.jboss.org/drools/release/5.4.0.Beta2/drools-fusion-docs/html/ch02.html#d0e289 I think the start and endtime time stamp statements in the documentation is for clarity.

Re: [rules-users] Drools Salience and no-loop
Perhaps I am building my packages weird but if all my drl/dslr are under the
same package the salience is honored and all the rules are fired in order.
Why would it work in this way? Since changing all the files to the same
package I have done 10 runs of the test with 100% success. Am I building the
kBase in weird manner(I don't think so but look below):
if (logger.isDebugEnabled()) {
logger.debug(Knowledge base with the following
changeset was requested
built
+ changeset);
}
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory
.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource(changeset),
ResourceType.CHANGE_SET);
KnowledgeBuilderErrors errors = kbuilder.getErrors();
if (errors.size() 0) {
StringBuilder sb = new StringBuilder();
for (KnowledgeBuilderError error : errors) {
sb.append(error + \n);
logger.error(error);
}
throw new IllegalArgumentException(Could not parse
knowledge. \n
+ sb);
}
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
return kbase;
Would this cause any fragmenting when the engine is indexing the rules for
activation? I would think not. I am just going by the current results I have
gotten by declaring all rules in the same package.

Re: [rules-users] Drools Salience and no-loop
Could be there is a race condition in the builder.
I would not use a changeset unless you really need dynamic changes of your
rules.
Simply feed the builder with DRL or whatever, create the Knowledge Base and
then
the sessions.

Why would it work in this way? Since changing all the files to the same
package I have done 10 runs of the test with 100% success. Am I building
the
kBase in weird manner(I don't think so but look below):
if (logger.isDebugEnabled()) {
logger.debug(Knowledge base with the following
changeset was requested
built
+ changeset);
}
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory
.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource(changeset),
ResourceType.CHANGE_SET);
KnowledgeBuilderErrors errors = kbuilder.getErrors();
if (errors.size() 0) {
StringBuilder sb = new StringBuilder();
for (KnowledgeBuilderError error : errors) {
sb.append(error + \n);
logger.error(error);
}
throw new IllegalArgumentException(Could not parse
knowledge. \n
+ sb);
}
KnowledgeBase kbase =
KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
return kbase;
Would this cause any fragmenting when the engine is indexing the rules for
activation? I would think not. I am just going by the current results I
have
gotten by declaring all rules in the same package.

[rules-users] How to include one .drl file from another .drl file
Is there something like #include for drl files? That is, something like this: rule 1 when then doSomething; end #include another.drl rule 2 when ... I know I can load multiple drl files into the knowledge base in Java.

Re: [rules-users] Duration attritube and Temporal Operators
Hi all, i have the same problem, i haven't well understood meaning and use of timestamp and duration fields. From my understanding, timestamp field is start time and duration is difference between end time and start time. Is it rigth? On the other hand, i know that it is a good practice don't change these 2 fields. I mean, it isn't suggested to modify duration or timestamp after that the event is inserted in session (is it right?) Furthermore, it is bad practice to insert an event with old timestamp, compared to system time. So, i don't understand, how is it possible to manage event with duration. If i have an event with timestamp t1 and duration 5s, of course i know it when it is finished, so i have to insert it into session with old timestamp. Sorry for bad English, i hope i was clear.

Re: [rules-users] Duration attritube and Temporal Operators
There are two values that Drools uses with facts that have been given @role(event): timestamp and duration. The timestamp may be a fact field, provided by you, or added automatically (in a hidden location) by Drools. If it is a field called x, you must say @timestamp( x ) in the declare. The duration field must be provided as a fact field, say y, so you must say @duration( y ) in the declare, or else duration is 0. @timestamp and @duration cannot be changed after the event's insertion. If you have an event whose end you don't know when you are informed about it's beginning, then you'll have to make do with two events, one marking the start and the other one the end. If you're in CLOUD mode, you can combine a start and a matching end event to one with a start and a duration and continue to reason with that. -W 2012/3/9 Matteo Cusmai cusmaimat...@gmail.com Hi all, i have the same problem, i haven't well understood meaning and use of timestamp and duration fields.
