sliding time in lhs
by Francesco Chiarelli
Hi!
i'm new to use a drools-fusion, i've a next lhs condition in rule:
$o: Order(status!="EU_C_R1_INIT")
SystemConfig(value:value) from hbnSession.createQuery("from
SystemConfig where name=:name").setString("name","nRicMax").uniqueResult()
$nRic : Number(intValue < value) from accumulate($n:
Order(this==$o) over window:time(1d),count($n))
Data:
1) Order 1 date 28 aug 2009 EU_C_INIT
2) Order 1 date 31 aug 2009 EU_A_INIT
3) Order 1 date 31 aug 2009 EU_B_INIT
4) Order 1 date 30 aug 2009 EU_B_INIT
5) Order 1 date 28 aug 2009 EU_A_INIT
6) Order 1 date 01 aug 2009 EU_A_INIT
7) Order 1 date 28 aug 2009 EU_C_INIT
8) Order 1 date 28 aug 2009 EU_C_INIT
Only the first condition is verified [ Order(status!="EU_C_R1_INIT") ]
altough there are facts that verify Order(this==$o) over window:time(24h) ]
There are n-k facts that don't verify a previous condition but them come
count also:
I espect that drools count a 2-3-4 but it count also 5-6-7: i'm confused
P.S. i did set a stream mode, i' had set a timestamp attribute in event fact
@timestamp(myTimestampLong), i tried with pseudo clock (making it advance
for new Date().getTime() or at origin, therefore 01 jan 1970 [without event
@timestamp attribute] )

Serialization of packages: InvalidClassException / serialVersionUID
by Bernd Rücker
Hi!
I really struggled some time with serialization issues: I want to create a
pkg and package that with the jar. From there I want to read it during
runtime.
Easy I thought. Drools 5 way should be to serialize the KnowledgeBase,
right? At least, this is what the AntTask does.
If I try to serialize the KnowledgePackage I get an excpetion anyway:
Okay. Back to the KnowledgeBase. Serialized with Drools 5.0.0.M4 and try
to read it with 5.0.0.M5:
Caused by: java.io.InvalidClassException:
org.drools.impl.KnowledgeBaseImpl;
local class incompatible: stream classdesc serialVersionUID =
-4540376767025107954,
local class serialVersionUID = -3186110098262381425
So it seems Drools Packages are NOT compatible between minor versions?
This would be a disaster for deployment. Or do I serialize the wrong
thing? Unfortunately I didnt find anything in the docs about it.
Then I tried to do it the old Drools 4 way and serialize Package
objects, but same problem with a different serialVersionUID!
Why do these important classes dont have a serialVersionUID? Or how
should that be loaded? Must be a big issue with Govner, so I think there
must be a solution already?
Thanks for any help!
Cheers

Why so many ACTIVATION/DEACTIVATION events?
by Tom.E.Murphy＠wellsfargo.com
We have a fairly complex object model, but we're still puzzled - I thought that the definition of "Activation" was that the data matched on all conditions of a rule, and therefore the rule was entered into the agenda (activated).
If that is true, I cannot figure out why we're experiencing this.
As our number of rules increases, we're seeing exponential increases in repetitive activation/deactivation pairs, even on rules where we know the data does not match the conditions.
Example:
The following rule (abbreviated here) creates an object of type PolicySet if there are none that match the conditions.
I would expect this rule to activate once, then fire, wherein the matching PolicySet is created, and then never activate again since the absence of a matching PolicySet object is never again true.
However, in a rule base of ~4,000 rules, we see this rule activating 975 times and deactivating 975 times. This is just one example - nearly all our rules do this, and it is seriously impacting decisioning performance.
Have I misunderstood the meaning of "activation"? Can anyone help me understand this?
rule "RS6090.1.12_RF7007_50001012"
when
LendingProduct ( $exitStrategyType1 : exitStrategyType )
Features ( $lienPriority1 : lienPriority )
DecisionResultsInfo ( $dealRiskCategory1 : dealRiskCategory )
TransactionDetail ( $parentTransactionDetail1Id : myId )
not
(
PolicySet ( $parentPolicySet_1_Id : myId, parentId == $parentTransactionDetail1Id )
and
PolicySetIdentifier ( parentId == $parentPolicySet_1_Id
, lienPriority == $lienPriority1
, exitStrategyType == $exitStrategyType1
, dealRiskCategory == $dealRiskCategory1)
)
then
// Content removed... rule creates the policy set and the policy set identifier, and initializes all appropriate elements
// After doing so, why does it activate/deactivate 1800+ times in a rule base of 4000 rules?
System.out.println("6090 fired.");
End
Thanks.
