September 2012 - rules-users - Jboss List Archives

by Ming Fang

Where can I find documentation on extending rules using the 'extends' keyword? The official documentation doesn't even list that as a keyword. I only found out about it by accident here http://blog.athico.com/2012/09/conditional-named-consequences-in.html

adding de-serialized packages to the rulebase takes 7 minutes time.

by subba

Hi, I am using drools 5.0.0 CR1 on sun sparc machine with JRE 1.6.0_12. The JVM has 2GB heap and 256 permGen settings. Recently I have noticed that the adding the deserialized package to the rulebase takes almost 7 minutes time. The serialized cache files contains 4000 rules and the file size is 40MB. The de-serialization is pretty quick but adding this package to the rulebase is taking lot of time. Other observations: ============= 1. The the task on windows PC takes lesser time. 2. During addpackage method execution, I had observed lots of Garbage collection happening though there is plenty of heap available. Can you please suggest a way to improve this task timing ? Regards. Subba. -- View this message in context: http://drools.46999.n3.nabble.com/adding-de-serialized-packages-to-the-ru... Sent from the Drools: User forum mailing list archive at Nabble.com.

Pattern Example

by thano

Hi, I am struggling to understand the concept of patterns. I have the following code which I would like as a generic threshold pattern. I have been told that it is not a pattern- thanks rule “DD” when # calculate the average requests made over 10 days $service: Service( ) Number ( $ averageRequest : doubleValue ) from accumulate ( RequestCompletedEvent (fromService = = $service, $request : request ) over window : time (10d) from entry-point RequestStream, average ( $request) ) # check if the requests made in the last 60 seconds are higher than then the threshold value $r : RequestCreatedEvent ( fromService = = $service, Request > $averageRequest over Window : time (60s) from entry-point RequestStream then # do something end -- View this message in context: http://drools.46999.n3.nabble.com/Pattern-Example-tp4019946.html Sent from the Drools: User forum mailing list archive at Nabble.com.
