<br><font size=2 face="sans-serif">Hi,</font>
<br>
<br><font size=2 face="sans-serif">This is perhaps not the performance
hit you think it is as the rules are evaluated as they are loaded. The
Rete algorithm will evaluate that the rule is not null and trigger.</font>
<br>
<br><font size=2 face="sans-serif">Another consideration is that you may
need to use a flatter fact-model if you're drilling down with 'from' operators
and needing to trap for nulls.</font>
<br>
<br><font size=2 face="sans-serif">Aside from that, if you use Rule Flow
Groups and a Rule Flow as Michael Anstis suggested:You can use a Split
Connector to branch around that section of ruleflow, and a Join Connector
to continue, connected either to the next ruleflow step, or to a Stop.</font>

<br><font size=3>I got great Idea by this discussion.</font>
<br>
<br><font size=3>If there is no way of stopping rules then I can do this
null condition check before executing rules. Adding one action in JBoss ESB
will solve problem.</font>
<br>
<br><font size=3>Please suggest me.</font>
<br>
<br><font size=3>Many Thanks in advance.</font>

<br>
<br><font size=3>But let us assume i have 100 rules based on single response.
When response is null then if i am doing null check in all rules then it
degrades the performance. My application hits are million per
day. if 1 % percent fails think about the impact.</font>
