[Design of Clustering on JBoss (Clusters/JBoss)] - Re: Next Gen Web Tier Load Balancing Design

by galder.zamarreno＠jboss.com

I agree. I'll work with Brian to include a section of failure/failover scenario in the wiki. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4116947#4116947 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4116947

[Design of JBoss Profiler] - cannot delete profiler log file

by jigu888

Hello, I am using jboss-4.0.5.GA and jboss-profiler-1.0.CR4. The java version is 1.5.0. My profiler log files are stored under D:\JBoss\jboss-4.0.5.GA\server\default\tmp\profiler folder. I have used following in run.bat: -XrunjbossInspector:%JBOSS_HOME%\server\default\tmp\profiler,memory=true -agentlib:jbossAgent I started jboss service and from jmx-console, used mbean=Native-profiler to start data capturing by invoking activate() method. After one day the jboss service stopped due to some exception and I tried to delete log files because I wanted to start the same again. I could able to delete all but one file. The name of that file is serverspy_1172_thread_1197325971140_0_38.log.gz. Do you have any idea why I am not able to delete this file? Its saying that "can not deletethe file. it is being used by another person or program. Close any programs that might be using the file and try again". The size of this file is 1.80 GB!! Can unexpected termination of jboss service be the reason behind this? I could not get chance to activate stop() method for mbean. Can this be a reason behind this problem? Did I miss anything or do anything wrong? Please advice. Thanks.

[Design of Clustering on JBoss (Clusters/JBoss)] - Re: Next Gen Web Tier Load Balancing Design

by andy.miller＠jboss.com

That's what I was looking for, at a minimum, but its not clear in the documents diagram that that would be done. In an alternative approach to HASingleton, you don't necessarily have to replicate load information across the cluster. You could use buddy replication, but as long as there is a master/slave relationship on the HASingleton, then I agree, this is all that is needed. It just wasn't clear in the document.

Re: HASingleton crash If there's any nodes in the cluster, one of them will become master and will restart the HASingleton. Obviously, there would be a gap during which information would not be sent back to httpd, but it's something that we can live with. While httpd does not receive load information, it can carry on applying existing rules. This is much easier that trying to maintain load information, that changes every minute, replicated accross the cluster.

[Design of POJO Server] - Re: migrating TransactionManager and Invokers to POJO

by scott.stark＠jboss.org

Yes, that is what should be done. http://jira.jboss.com/jira/browse/JBAS-5103 can be used for subtask issues related to the move.

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: NPE booting Embedded JBoss from trunk

by pete.muir＠jboss.org

It's probably easiest to replicate by running from the Seam testsuite You need current Seam CVS. cvs -d:ext:USERNAME@cvs.forge.jboss.com:/cvsroot/jboss co jboss-seam | cd jboss-seam/src/test/integration | ant testclass -DclassName=MessagingTest The tests are in jboss-seam/src/test/integration/src/org.jboss.seam.test.integration.MessagingTest If you want to look at the xml's (including log4j configuration) they are in jboss-seam/bootstrap.

[Design of Clustering on JBoss (Clusters/JBoss)] - Re: Next Gen Web Tier Load Balancing Design

by andy.miller＠jboss.com

I read through the load balancing design doc, and I have a couple of observations. First, I think you need to consider having the load manager component to at least have a master/slave concept (and maybe many slaves). What happens to the HASingleton if that node crashes? There wouldn't be anything communicating load information back to the httpd. Second, I think you need to consider the common topology of when httpd is sitting in a DMZ, and communication is across the inner firewall. I know at my last employer, our security policy would not allow http/s to be over a non-standard port outbound (which the AS side would be going outbound to mod_cluster), and for the inbound side from httpd through the inner firewall to the AS we wouldn't allow http/s, as this would only be allowed to be open on the outer firewall into the httpd servers. Only application specific protocols like AJP were allowed through the inner firewall. We also preferred to have those protocols be encrypted with TLS, so for our configuration we would use stunnel, but that is a band-aid. I think we should consider a TLS option on the AJP, or whatever protocol we use for mod_cluster to talk to the AS side.

I suspect this is some configuration problem with our xml, but as the error message isn't helpful :p I'm not sure | Being honest to you, I don't know how to run embedded.... If you give me some instructions I will try to replicate it here. Probably there is some problems on the ordering of startup when you're running embedded. I will try to work around if you give me some instructions.
