Good Morning Mr.Laun, Yes you are correct.But request you to send me sample code for that sort of application as how to write ro implement rules. what class need to be written and rules related to that. waiting for your response thanks in advance    venkat

[rules-users] Rules packaging and (binary?) reuse: searching for best practices

Hi all, I'm in search of a better way to package rules into a binary format before they get deployed - one that eases rules reuse more than the technique currently in use at my employer. We're using drools expert to perform risk assessment and feasibility checks for mortgage loans of a signifi

Re: [rules-users] Questions about using Knowledge Agent

Hi John, Knowledge Agent is indeed the replacement of RuleAgent. It maintains a kbase and update it using change sets. A change set is an xml that list all the resources that the agent should take care of. In conjunction with ResouceChangeNotifier and ResourceChangeScanner you can use a knowledge a

Re: [rules-users] Parallelization

If you're using the sun VM multiple Threads will use multiple cores just fine. What version of java? Are you intending to max out the CPU on the machine? If so I suggest this configuration, for an 8 core box: 7 Threads, each running a StatefulKnowledgeSession. Concurrent garbage collection,

Re: [rules-users] Rule salience vs salience of ruleflow executions?

Those maintenance rules possibly make other rules in my ruleflows re-evaluate and I need to share them across my ruleflow because they are applicable everywhere. In this particular case, I have a rule saying that if an error status is flagged (different from exception), halt drools and return. Th

Re: [rules-users] Parallelization

I'm not a guru but I'm pretty certain all modern JVMs support multiple cores well. You will probably make sure you are using the server VM (-server) and not the client VM (assuming you are using the standard VM). Depending on what you current machine is and whether or not you have 2 cpu's or j

Re: [rules-users] Parallelization

Hi Daniel, I was reading the other day that a JVM implementation does not necessarily have to run Java threads in different Processes (taking advantage of multiple cores). If you saw a significant speedup then I would assume your JVM does this. It is worth investigating for your production d

They are for simple CEP type applications, you won't see a benefit else where, possibly a slow down if you are doing more business type rules. Mark On 11/05/2010 09:40, djb wrote: > Hi Drools squad, > > This is a follow-up to my previous speed-related post. By boss is still > pushing to get 35ms

Re: [rules-users] Regarding Jboss drools rules

If I understand you correctly, you just have to classify data records (facts) as "passed" and "failed". If possible, add another field "result" to the class representing your "record" which may assume the values "undef", "passed", "fail". Write rules to detect the "passed" objects with result ==

Can you make an extra step? why not just put your rules before the split, in the rule-flow? -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Rule-salience-vs-salience-of-ruleflow-executions-tp807973p809775.html Sent from the Drools - User mailing list archi

Re: [rules-users] Parallelization

Does your system support parallel execution of Java threads on multiple processors? Otherwise I don't see how parallelization will gain much since the Rete evaluation itself is clearly compile-time bound. How are you timing these 53ms? Does this include input time for your facts? Frequently, much

Re: [rules-users] Regarding Jboss drools rules

One option is, in the consequence part of your rule, to say String ruleName = drools.getRule().getName(); and then store that in a global variable. That will let you see afterwards which rules fired. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/
