Please if any one know give me some link, or sample example, or
suggest how to do this, Thank u in advance
I am Having 1000 rules and i want to make each 100 rules as one set, so i
will 10 set , can i fire only 1 set when necessary, can i add a new rule to
existing set dynamically,
what is necessary of making more than one drl files, and how to load all drl
at once.
I am very new to drools.. Please suggest me some solution

New subject: I have 1000 rules, i want to create each 100 as one set , and fire each set when necessary
Depending on the cohesion of your rules you could have multiple solutions
to this scenario.
1. Having different knowledge bases each one containing a set of rules.
A knowledge base is basically a collection of rules, so you could have 10
different kbases. The issue here is that the set of Facts (the objects you
insert in a session) is not going to be shared between the different
sessions of your different kbases. So you will need to insert them in the
corresponding ksession.
2. Having 1 kbase but separate the rule *execution* using agenda-groups.
Please read the documentation for further information about agenda-group:
http://docs.jboss.org/drools/release/5.3.0.Final/drools-expert-docs/html_...
3. Use jBPM in conjunction with rule-flow-group attribute in your rules
to control the execution flow of your rules.

Take a look at using RuleFlow-Group. All you need to do is to create the ruleflow diagram
in eclipse (or using a text editor), then load this into your rules. For each group of
rules, assign the ruleflow-group name for each group. So in your case, your ruleflow
might be: (this is for 5 groups)

Then in your rules, just assign each rule to one of:
ruleflow-group 'init'
ruleflow-group 'validate'
ruleflow-group 'post-init'
ruleflow-group 'phase_1'
ruleflow-group 'phase_2'
you will need to use a StatefulKnowledgeSession, as the StatelessKnowledgeSession does not
work (though I have not tried stateless ruleflows in 5.3 yet).
Drools will then fire the first ruleflow-group as defined by the bpmn file, when all rules
have fired and the agenda is empty, it will move on to the next ruleflow-group.
You can also create a rule that moves the ruleflow to the next group, however, I
discourage doing this, as the rules become overly complicated and thus harder to decode
what is going on when rules don't fire (because the rule that switched the ruleflow
group fired sooner than you expected).
