[Performance Tuning] New message: "Re: Memory consumption 1h after JBoss start"

by luv zorabian

User development, A new message was posted in the thread "Memory consumption 1h after JBoss start": http://community.jboss.org/message/521650#521650 Author : luv zorabian Profile : http://community.jboss.org/people/luv Message: -------------------------------------------------------------- I think its because of concurrent hits due to load testing. For example for the production there is no need to generate the application server log and application log. It reduce the performance by 1.6 to 2 times. Better way for load testing would be try after stopping the log. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521650#521650

[jBPM] New message: "Re: Process definition deployment"

by Walter Seymore

User development, A new message was posted in the thread "Process definition deployment": http://community.jboss.org/message/521647#521647 Author : Walter Seymore Profile : http://community.jboss.org/people/WalterJS Message: -------------------------------------------------------------- Hi Maarten, The process needs to be deployed once into the db. Only if you have a change to the process definition, do you need to redeploy and it will automatically create a new version in the db. By default, new processes will use the new definition. Cheers Walter -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521647#521647

User development, A new message was posted in the thread "jbpm 4.3 - org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update": http://community.jboss.org/message/521622#521622 Author : Martin Porter Profile : http://community.jboss.org/people/jedizippy Message: -------------------------------------------------------------- Hi, This is basic plain vanilla jBPM 4.3 deployed as an EAR to a single standalone instance of WLS (not clustered). Our jbpm.cfg.xml is just importing the Job Executor so we have not changed any of the threads or lock values so it should be using the default 3 threads according to the docs- <import resource="jbpm.jobexecutor.cfg.xml"/> We are running in a JTA enviroment and reading the latest 4.3 docs we should be importing the jta config:- <import resource="jbpm.tx.jta.cfg.xml"/> I will try this as currently we have been using the basic hibernate tx config:- <import resource="jbpm.tx.hibernate.cfg.xml"/> I am not sure if this would have any bearing on this problem or not. I will look into it further today and see if this has any bearing. We are running against Oracle 11g so its seems then that its not related to the DB according to Tians post.It would seem as you say the problem lies in the unique ID generation for the execution id.

[jBPM] New message: "Process definition deployment"

by Maarten G

User development, A new message was posted in the thread "Process definition deployment": http://community.jboss.org/message/521614#521614 Author : Maarten G Profile : http://community.jboss.org/people/magoris Message: -------------------------------------------------------------- Hi, I am developing a web app with JSF 1.2, Spring 2.5.6 and jBPM 4.3. I have integrated jBPM with Spring so I can use the jBPM 4.3 services as Spring beans. I can't get the process definition deployment to work as I want though. When the app starts/restarts I deploy the process definition with the following code, as I want to be sure the process is deployed when the web app is running: repositoryService.createDeployment().addResourceFromClasspath("process.jpdl.xml").deploy(); which works the first time, but on a following server start/restart i get the following exception: org.jbpm.api.JbpmException: error: process 'process-1' already exists I suppose this is because i have version="1" specified in the process definition. When I remove the version it works, but then it deploys a new version to the db every time, which seems illogical to me as it is the same process definition each time. Is this what is supposed to happen, or is there a way to check if a certain process version is already deployed, so it runs the deploy() code only when necessary? Any help with this would be greatly appreciated, this is the first time I use jBPM in a project.

[Beginner's Corner] New message: "How do I enable pass-by-reference for EJB3 in JBoss AS container?"

by Jerry Simone

User development, A new message was posted in the thread "How do I enable pass-by-reference for EJB3 in JBoss AS container?": http://community.jboss.org/message/521600#521600 Author : Jerry Simone Profile : http://community.jboss.org/people/jlsimone Message: -------------------------------------------------------------- I am converting a somewhat large application from EJB2/WebSphere to EJB3/JBoss. In EJB2/WebSphere,I am able to configure the WebSphere container to use pass-by-reference between EJBs that coexist in the same JVM. I would like to do the same with the JBoss AS. I have done some research and saw some documentation that says you can use the <container-invoker-conf> tag in the jboss.xml file to optimize the calls within the container JVM. But I get the feeling that this is old, outdated information. So far, I have not been able to verify this with any information that I have found on the "current" (JBoss AS 5.1) jboss.xml file. Can some one point me to an article or the documentation that might clarify this for me? Thanks -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521600#521600

User development, A new message was posted in the thread "Problem Signaling a Waiting Execution": http://community.jboss.org/message/521583#521583 Author : Ronald van Kuijk Profile : http://community.jboss.org/people/kukeltje Message: -------------------------------------------------------------- sure, just make sure the database you use in your testcase references the same database as your console. Deploying then via the testcase makes it visible in the console. You can also upload via the console or... in jbpm 3, deploy via the deploy tab in eclipse when you have the processdefinition in the designer open. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521583#521583

[JBoss Cache] New message: "How do I avoid cluster collisions on the same subnet for cache invalidation?"

by Josh Long

User development, A new message was posted in the thread "How do I avoid cluster collisions on the same subnet for cache invalidation?": http://community.jboss.org/message/521581#521581 Author : Josh Long Profile : http://community.jboss.org/people/starbuxman Message: -------------------------------------------------------------- Hello, I have a setup with JBoss Seam. I'm using JBoss Cache as the backing caching framework for JPA (Hibernate). I also accquire a reference to the Cache that HIbernate creates when it starts up and get at a few cache configurations of my own for other purposes (ie, theres enitty-cache, query-cache, etc, that are there for Hibernate, and theres another configuratio that I use for my own purposes.) The effect is thatId ont have to create two cache instances in the same web application. Now, my problem: jboss cache is clustered. It has a clusterName attribute. If i launch the jboss cache instance in two different environemtns but the same subnet (staging, test, for example) theres teh risk of collision - how do I ensure that thed query-cache from staging doesnt share /replicate/invalidate the query-cache for testing? I looked at the cluster name attriute for each config in jbc2.xml (we have a custom one that's based on the default one), and that might work as long a I change the cluster names for each build. Id also need to bifurcate the persistence.xml into two separate configurations or do some sort of nasty property filtering so that I can confure stagins query cache as: hibernate.cache.region.jbc2.cfg.query=staging-query-cache in staging, and hibernate.cache.region.jbc2.cfg.query=test-query-cache in test. So, what Im asking is: a) is cluster name the way to ensure two clusters dont trample on each other? b) is there another way that doesnt leave me creating two diffrent jbc2.xml and persistence.xml files for each environment, or at least reduces it? I noticed that you can interpolae system properties in jbc2.xml - but not in persistence.xml, which means I couldnt just use a system property and cange it per environment in the tocat startup script. Thanks, any and all insight's appreciated. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521581#521581
