[Performance Tuning] - High CPU Utilization

"High CPU Utilization"

Hi ,
We have started our application with following settings.
$JAVA_OPTS -Xmx4096m -Xms4096m -Xmn2g -Xss128k -XX:ParallelGCThreads=8 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:SurvivorRatio=8 -XX:TargetSurvivorRatio=90 -XX:MaxTenuringThreshold=31 -XX:MaxPermSize=512m -XX:PermSize=256m
We are sending the direct http requst to our application.
It causing the CPU Utilization in the range of *80-85 %.*
When we tried jst returning back from the Method with Null response Our CPU Utilization is in the range of 45-50%
We are using the axis2 webservice in it.
| %1,3% *Hardware Configuration* |
| %4% Application Node | *No of CPU* | *8* |
| CPU Type | Intel(R) Xeon(R) CPU E5530 @ 2.40GHz, cache size 8192 KB |
| *Memory* | *8 GB* |
| Network Card | 100 mbps Ethernet |
| %4% Database server | No of CPU | 8 |
| CPU Type | Intel(R) Xeon(R) CPU E5620 @ 2.40GHz, cache size 12228 KB |
| Memory | 160 GB |
| Network Card | 100 mbps Ethernet |
So currently we are struggling to reduce the CPU usage.

[jBPM] - jBPM architecture and clarifications

"jBPM architecture and clarifications"
To view the discussion, visit: https://community.jboss.org/message/737667#737667
--------------------------------------------------------------
Hello,
I am really new to jBPM 5.2 since this week (!) . Till now I installed the demo, played a little with it and the console, and went through the documentation.
But some things are really not clear for me. I went through the forum without beeing able to find a clear answer to my questions.
1. In the documentation "Chapter 1 overview", it is written that "it can run in any Java environment, embedded in your application or as a service". So I clearly undestand that I can develop my Java application and use the KnowledgeBase, KnowledgeBuilder... to add some processes (*.bpmn files), start processes and so one. But I don't understand what it means to run jBPM as a service and it doesn't seem to be explained in the documentation. Can someone explain that please?
2. On the forum, I found also a lot of people saying that they are running jBPM in jBoss. What does it mean too? Is there a way to put jBPM in jBoss and to access it from several others separated applications?
3. For my developments, I imagine an architecture with jBPM running in standalone mode in a simple Java application, jBPM beeing in a persistent mode. Also the human task service would be running in a single place. Then I would have different applications which could connect to the single jBPM to start processes and so one. But I can't find some explanations about how to put in place such an architecture. I can only find some people saying to use the REST interface of the console. But in my application there will be no console deployed. So... can anyone can help on this?
Thank you all in advance.
Jena

[Beginner's Corner] - Migrate Drools 4.0.7 from JBoss 4.2.3 to JBoss7

"Migrate Drools 4.0.7 from JBoss 4.2.3 to JBoss7"

--------------------------------------------------------------
Hey folks,
I migrate an application from JBoss 4.2.3 to JBoss 7. The application uses Drools 4.0.7. (and I´m noob to Drools and JBoss)
In the old JBoss version the drl files were not included in the EAR file. The conf folder was the directory for the drl files. We´d like to keep the structure in JBoss7 and use the JBoss\standalone\configuration for the files.
So I put the Drools JAR files in the lib directory. Then I configured the path to the drl files in my application to JBoss\standalone\configuration. When I start the server I get a (lot of) warning(s) like:
(alpha, beta are placeholder[company issues])

The Drools are called from the beta-ejb.jar. The directorys in my EAR file are lib, META-INF, beta.war, beta-ejb.jar, beta-test-ejb.jar
I´d like to know:
1. Is it possible to use Drools 4.0.7 with JBoss 7?
2. Can configure the path where the Drools lookup the classes?
3. What the hell is wrong? It seems like the Drools tool can not find my classes, or am I wrong?
I googled a time and found nothing. But I think these are easy questions for the JBoss/Drools masters in this community!
With hope and regards,
Christian
