Re: [rules-users] Weblogic rules to Drools rules.

Yes we have around 15-20K rules & each rule have different set of conditions ANDed/ORed. Some rules are small have 10-15 conditions but some have more than 100 conditions to be fullfilled to trigger the rule. The eval() function was taking time & never loads the single rule. So today I change my logic & start using java beans, & insert the patient profile/data in CDEntryCache bean this will not fullfilled all of us condition, as we have some complex matching condition need to communicate with db e.g drug formualrtions etc but to give a try, I create the rule as follows: Following rule having some conditions which should be matched with WM(patient profile) to trigger the alert. #created on: Jan 29, 2009 package my.rule;
