Re: [rules-users] Web Service deploy out of memory
Hi Edgardo. Good to hear. Yeah it was probably creating a new daemon thread
for each instance in that case, which would top out on 1000 to 3000 items on
most systems today, so that is not surprising ;)
Good luck !

Thanks Michael, the problem was that every call to the web service create
a new instance of ValidaLlamadaWS, because the system memory explode!. I
fix it managing the session scope of the Web Service, now my drools + web
service implementation works fine!
Thanks for you reply
Greetings, I see you in another post

Hi Edgardo.
Well it shouldn't leak like that.
Looking at your code, I am not sure how it works (as I am not sure of
the
Web Service component you are using).
But if the web service is creating a new instance of the
ValidaLlamadaWS
class for EACH call, then yes that woudl be the problem. What you want
to do
is have the code for the agend called only once, on startup, and then
use
that single instance of the agent to get a rulebase for each call.

Hi list,
I have developed a web service for deploy my rule package, this
rule
package is in the BRMS, the source code of the web service class is:
public class ValidaLlamadaWS {
RuleAgent agent = RuleAgent.newRuleAgent
(/brmsdeployedrules.properties);
RuleBase ruleBase = agent.getRuleBase();
StatelessSession session = ruleBase.newStatelessSession();
public Object[] ValidaLlamada(Integer cantsegundos){
Validaciones validaciones = new Validaciones();
validaciones.setCantsegundos(cantsegundos);
session.execute(validaciones);
return validaciones.getResult ();
}
}
The BRMS run over JBoss AS 4.2.1.GA and the web service over Apache
Tomcat
5.5 on the same machine, the rule base contain only 2 rules
The problem is that I need to call the web service more than 400.000
times, and with 1000 times, I obtain the Java Heap Exception.
If I monitoring my machine memory, this only increase between calls.
And
the process that more memory expensive is java.exe (JBoss AS
4.2.1.GA).
The process javaw.exe (Apache Tomcat 5.5)also is expensive, but less
than
java.exe
The question are:
How I can dispose the objects that I use?
Is correct this use for StatelessSession?
You are the experts, any other idea for implement my web service?
PD: sorry for my bad english.
Greetings
