Hi Stathis<BR> <BR>You're probably right, maybe it's a wrong question, i'm new to Drools, so I copy the rule sample from user guide as below to better explain, that's what i need, but the rule will be automatically generated in the future..<BR> <BR><pre xmlns="" xmlns:d="http://docbook.org/ns/docbook" xmlns:rf="java:org.jboss.highlight.XhtmlRendererFactory"><a id="d0e254">package com.company.license
rule "Is of valid age"
when
$a : Applicant( age < 18 )
then
$a.setValid( false );
end</a></pre> <BR>So in the future the rule may include more and more conditions like below:<BR> <BR><pre xmlns="" xmlns:d="http://docbook.org/ns/docbook" xmlns:rf="java:org.jboss.highlight.XhtmlRendererFactory"><a id="d0e254">
rule "Is of valid age2"
when
$a : Applicant( age > 18 and age < 20 )
then
</a></pre><pre xmlns="" xmlns:d="http://docbook.org/ns/docbook" xmlns:rf="java:org.jboss.highlight.XhtmlRendererFactory">...</pre><pre xmlns="" xmlns:d="http://docbook.org/ns/docbook" xmlns:rf="java:org.jboss.highlight.XhtmlRendererFactory">end</pre><br>So it may grow to be a very large rule(?), and this is actually my question: how to handle this big rule?

Any idea? Thank you guys. CheersRamon<br>> <br>> You are either asking the wrong question or you do not understand what you<br>> are asking.<br>> <br>> In your previous post, you mentioned a Knowledge Base of 100GB.<br>> In this post you are talking about a rule set.<br>> These are different things.<br>> A Knowledge Base contains rules *and* facts and can indeed be quite large.<br>> A rule set contains only rules. For a rule set to grow this much, it means<br>> you have seriously misunderstand your problem. I would suggest you go back<br>> to the drawing board.<br>> <br>> Real-world example:<br>> Rule set of about 400 rules.<br>> Facts : In the order to 100.000.<br>> Command line execution shows an approximate 400MB RAM consumption, meaning<br>> with the JDK and all (not only Drools memory consumption).<br>> <br>> So, unless you want to hear from someone more experienced than me, I'd<br>> suggest you re-phrase your question by stating the exact problem you are<br>> facing or anticipating.<br>> <br>> Cheers,<br>> -Stathis<br>> <br>> <br>> <br>> > From: ramon_wang@hotmail.com<br>> &g
