[Design of JBoss Serialization] - Using customized RMI socket factory with JBOSSSerialization

by yaishb

Hello all, We are trying to imrove RMI performance in one client-server RMI application. we customized RMI socket factory (client and server), which uses customized Socket and ServerSocket, which use JBOSSObjectInputStraem and JBOSSObjectOutputStraem (is this the correct way to use jboss serialization in RMI?). One flow in the client application invoke many time Naming.lookup() on the server rmi registry. If not using the customized socket factory (hence not using jboss serialization) - everything works great. If using the custmozied socket factories, OutOfMemoryError is raised: java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start0(Native Method) at java.lang.Thread.start(Thread.java:597) at sun.rmi.transport.DGCClient$EndpointEntry.(DGCClient.java:231) at sun.rmi.transport.DGCClient$EndpointEntry.lookup(DGCClient.java:202) at sun.rmi.transport.DGCClient.registerRefs(DGCClient.java:120) at sun.rmi.transport.ConnectionInputStream.registerRefs(ConnectionInputStream.java:80) at sun.rmi.transport.StreamRemoteCall.releaseInputStream(StreamRemoteCall.java:138) at sun.rmi.transport.StreamRemoteCall.done(StreamRemoteCall.java:292) at sun.rmi.server.UnicastRef.done(UnicastRef.java:431) at sun.rmi.registry.RegistryImpl_Stub.lookup(Unknown Source) at java.rmi.Naming.lookup(Naming.java:84) at com.commons.pattern.barakota.HashRAMRMIClient.lookup(HashRAMRMIClient.java:483) at com.commons.pattern.css.rmi.RMICSSClient.initializeDelegatesPool(RMICSSClient.java:70) at com.commons.pattern.css.CSSPeer.init(CSSPeer.java:35) at com.commons.pattern.barakota.HashRAMRMIClient.(HashRAMRMIClient.java:36) at com.storing.context.StoringContext$HashRAMBooter.run(StoringContext.java:908) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:885) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:907) at java.lang.Thread.run(Thread.java:619) Can you please assist with debugging this behaviour? Thanks, Barak.

Just ensure that there are no test suite failures. I do see some security failures that is due to some xml parsing or such issues (ant tests-security-basic-unit). Not sure if your changes to client classpath (endorsed) is the cause or some new mc/deployers release is the issue.

I think I got it: when under jdk16 both the server and the client need to point to lib/endorsed to pick up the correct apis.

I'm also seeing that the delta of instance allocations to AbstractVFSDeploymentUnit is non-0 after running the tests..

This is *kind of* a dev question. :) I'll answer this because it promotes some great software generously provided to us for free via an open source license: JProfiler 5.1.4 from ej-technologies, http://www.jprofiler.com S, ALR View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4175626#4175626 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4175626

[Design the new POJO MicroContainer] - Re: JBMICROCONT-336; empty string failure

by alex.loubyansky＠jboss.com

You should know that with that annotation the simple content is always present and never null. So, I guess it may override some value somewhere or affect some if-condition since it's never null now.

Hm, it could be a testsuite setup issue. I think I had fixed that in Branch_4_2 at some point. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4175612#4175612 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4175612
