Re: [rules-users] Duration attritube and Temporal Operators
Pretty sure I am correct, think the devs are at a conference this week in London. http://blog.athico.com/ 1)Start time , point time interval. 2)Don't know exactly, I think the documentation is just showing what is meant. 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. When working with the rules we have , reading the documentation let me know if the temporal operators is what I needed. On Mar 8, 2012 11:55 AM, mind gil.vegli...@gmail.com wrote: Hello everybody, I recently started using Drools (with C#) and I have some problems in understanding how temporal operators work with the duration field. According to the documentation, the temporal operators work with startTimestamp and endTimestamp of events, the semantics being defined with inequalities. In order to work, temporal operator requires the duration field to be declared. Now the questions: 1. What does @timeStamp stay for? The start or the end timestamp? 2. Does Drools calculate startTimestamp and endTimestamp if I set @timeStamp and @duration attribute from my C# code? If not how can I set them? (like shall I declare like @startTimeStamp(sth) and set from the C# code?) 3. Do temporal operators work if I do not set explicitly the start and end timestamps but just @timeStamp and @duration attributes? In particular, I have this drl file (%VAR% are replaced by other code): declare IntensionalEvent @role(event) @timeStamp(timeStamp) @duration(duration) end rule Expression (%EVENTNAME1%, %OPERATOR%, %EVENTNAME2%, %TIMESPAN%, %TIMEVAR%) dialect mvel when $eventA : IntensionalEvent( name == '%EVENTNAME2%' ) $eventB : IntensionalEvent( this %OPERATOR% $eventA, name == '%EVENTNAME1%' ) over window:time( %TIMESPAN% ) then blah blah... create an IntensionalEvent and set timestamp and duration end Thanks everybody, Gil -- View this message in context: http://drools.46999.n3.nabble.com/Duration-attritube-and-Temporal-Operators-tp3810201p3810201.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] java.lang.ArrayIndexOutOfBoundsException thrown in mvel2's compiler when running drools5.3 final.
I am no drools expert but I am working a few mvel bugs in free time. I
am still sorting through the code.
I will try to work in test case but I don't know where
the line
Helper.containsAny(offerSubject, ((Set)colMap.get(_set_212))) is
coming from.
This isn't in one of your rules is it?
The index out of bounds is from the mvel code.
Pretty sure one of the project maintainers will give us more to go with.

hi all,
the exception below is usually thrown when the system is busy(usually 9-10
am everyday);
The rules runs perfectly when unit test or any other time when the system is
not very busy(like 22:00 - 4:00 every day);
Our system processes 1300 pieces of data each day, with
4-5 java.lang.ArrayIndexOutOfBoundsException thrown on average.It's not very
often but doubtful.
The logs are shown below:

Re: [rules-users] Removing many facts have invalid timestamp
It isn't duplicates but corrupted data coming off an vehicle. There is bug
in the vehicle code that isn't zeroing out memory, or updating a time value
during reset procedure which causes a bunch of facts to have the same end
time stamp. We cannot really change the vehicle code because it was
certified by the government and it is going to be a while before another
one is certified.

Would you please define unambiguously what constitutes an invalid time?
From your code it would appear that one time has to occur fivefold or
more often to
be invalid.
In case any duplicates should be removed a simple high-priority rule
is sufficient:
rule killDuplicate

when
$f1: Fact()
$f2 :Fact( endTime == $f1.endTime )
then
retract( $f2 );
