[Installation, Configuration & Deployment] - VM-Size in Windows task manager increases constantly

by ms＠camos.de

I got a big problem. Please give me some hints how to solve it. I read a lot of threads about it here, but no solution. My system is: P IV, 4GB mem (no swap to not delay the problem) Windows 2003 Server x64 SUN JDK 1.5.0-07 for AMD x64 JBoss 4.04 My own stateful session bean and two servlets of my own JBoss/JVM parameter: set JAVA_OPTS=%JAVA_OPTS% -Xms2048m -Xmx2048m set JAVA_OPTS=%JAVA_OPTS% -XX:PermSize=150m -XX:NewRatio=3 My problem is: To stress test my bean I create approximately 600 instances. One hour after the start the windows task manager tells me a VM-Size of 2.5 GB. That?s okay. Visual GC 3.0 tells me the following: PermSize: 50MB (ok) OldGen: 300MB (ok) (after 2 collections) Survivor ½: 130MB (ok) Eden: 170MB (ok) Everything is okay. After 30 hours Visual GC: PermSize: 50MB (ok) OldGen: 300MB (ok) (after 500 collections) Survivor ½: 8MB (interesting, but still ok for me) Eden: 33MB (interesting, but still ok for me) The Problem is now windows task manager for java.exe MemUsage: 1.6GB (ok) PeakMemIsage: 1.6GB (ok) VM Size 3.5GB (and increasing: very big problem) When VM-Size reaches 3.8GB, java.exe crashes. IMHO JVM?s internal heaps are okay but there must be an internal error in its memory management. It?s not that I want memory returned to the OS but the JVM should detect a lack of fresh memory and not allocate anymore. I also think that there is no benefit in changing Xms Xmx Xss (the well known switches). I tried without success. Is it possible that this is a special problem of the x64 JVM? With 32 Bit I run onto other limitation. Any help is welcome Thanks in advance.

[Security & JAAS/JBoss] - Re: Security chptr says ejb-jar.xml. But EJB3 has no ejb-jar

by Markus.Wahl

"j2ee_junkie" wrote : Since the SecurityDomain is a JBoss specific configuration, it does not go in the ejb-jar.xml. I figured you would have known how to configure JBoss. In this case, see the jboss.xml file and it's DTD for definitions. ok thanx, I'll do that. but couldn't I declare the securitydomain in jboss-app.xml instead of jboss.xml?

[Clustering/JBoss] - Re: Singleton Failover

by chanyungwan

Thanks for the reply. I tried to modify the cluster-service.xml by adding FD_SOCK as follows: : <FD_SOCK up_thread="true" down_thread="true" /> <FD shun="true" up_thread="true" down_thread="true" timeout="2500" max_tries="5" /> : Also, different version of jgroups.jar are being replaced a)2.2.4 <---default in 3.2.5 b)2.2.8 c)2.3 sp1 However, the timing issue is still unresolved for the 2nd case. Is this the bug for 3.2.5 release ? We are not intended to upgrade the version by the way. So, any other solution can be provided ? Many thanks.

[JBoss jBPM] - Re: JBPM TaskCreation at RunTime

by abbasshah

I agree task should not be used in STP process they are meant to be UserTasks, in real time even in my process it wont be the case. However i am writing my Unit test which deploys, executes and test some flows by completing some task without commiting anything into the database becuase i do not wish my testcases to change the database state.. I like my test * Not * to presist or change state of application shared data (database). So if you have transactions it is much simpler and clean by doing rollback in teardown. OR 2nd approch would be to persist and then remove it. it is possible to remove not only process defination, but process instance and other related enteries in other tables. ? Also if TaskInstanceId = 0 then does it means that task is not actually created? i think 0 is defualt value of TaskInstance.Id (if i am not wrong) abs View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3959038#3959038 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3959038

There doesn't seem to be any thing posted on this message group relating to deadlock using Sybase Anywhere (ASA). There is a post relating to sysbase EAS http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3864492 which is a different database. The create table parameter "LOCK DATAROWS" doesn't exist in Sybase Anywhere (ASA).
