Lookup fails during failover ---------------------------- Key: JBAS-3639 URL: http://jira.jboss.com/jira/browse/JBAS-3639 Project: JBoss Application Server Issue Type: Bug Security Level: Public (Everyone can see) Components: Clustering Affects Versions: JBossAS-4.0.4RC1, JBossAS-3.2.6 Final Environment: jboss 3.2.6 OS: SUSE LINUX 10 Reporter: Sangeetha Pisharody Assigned To: Brian Stansberry I have a 4 node jboss(3.2.6) cluster. I have a test MBean that runs as a HASingleton on this cluster. All the test MBean does is lookup XAConnectionFactory. Here is the code that does the lookup Properties p = System.getProperties(); p.put(Context.PROVIDER_URL, "localhost:1100"); Context jndiContext = new InitialContext(p); jndiContext.lookup("XAConnectionFactory"); I tried to stop jboss on the master node and this failed. During this period, another node tried to started this service and it could never get a XAConnectionFactory. This is the exception it threw javax.naming.NameNotFoundException: XAConnectionFactory at org.jboss.ha.jndi.TreeHead.lookup(TreeHead.java:237) at org.jboss.ha.jndi.HAJNDI.lookup(HAJNDI.java:148) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.jboss.ha.framework.interfaces.HARMIClient.invoke(HARMIClient.java:201) at $Proxy42.lookup(Unknown Source) at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:621) at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:583) at javax.naming.InitialContext.lookup(InitialContext.java:347) at com.racoman.ccc.mbeansUtils.jmsMonitorService.TestFailoverService.connectToMessageQueue(TestFailoverService.java:133) at com.racoman.ccc.mbeansUtils.jmsMonitorService.TestFailoverService.startSingleton(TestFailoverService.java:62) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.jboss.mx.server.ReflectedDispatcher.dispatch(ReflectedDispatcher.java:74) at org.jboss.mx.server.Invocation.dispatch(Invocation.java:76) at org.jboss.mx.server.Invocation.dispatch(Invocation.java:68) at org.jboss.mx.server.Invocation.invoke(Invocation.java:96) at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:213) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:484) at org.jboss.ha.singleton.HASingletonController.invokeSingletonMBeanMethod(HASingletonController.java:207) at org.jboss.ha.singleton.HASingletonController.startSingleton(HASingletonController.java:144) at org.jboss.ha.singleton.HASingletonSupport.makeThisNodeMaster(HASingletonSupport.java:197) at org.jboss.ha.singleton.HASingletonSupport.partitionTopologyChanged(HASingletonSupport.java:133) at org.jboss.ha.jmx.HAServiceMBeanSupport$1.replicantsChanged(HAServiceMBeanSupport.java:211) at org.jboss.ha.framework.server.DistributedReplicantManagerImpl.notifyKeyListeners(DistributedReplicantManagerImpl.java:780) at org.jboss.ha.framework.server.DistributedReplicantManagerImpl._remove(DistributedReplicantManagerImpl.java:587) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.jgroups.blocks.MethodCall.invoke(MethodCall.java:236) at org.jboss.ha.framework.server.HAPartitionImpl.handle(HAPartitionImpl.java:898) at org.jgroups.blocks.RequestCorrelator.handleRequest(RequestCorrelator.java:615) at org.jgroups.blocks.RequestCorrelator.receiveMessage(RequestCorrelator.java:512) at org.jgroups.blocks.RequestCorrelator.receive(RequestCorrelator.java:326) at org.jgroups.blocks.MessageDispatcher$ProtocolAdapter.handleUp(MessageDispatcher.java:722) at org.jgroups.blocks.MessageDispatcher$ProtocolAdapter.access$300(MessageDispatcher.java:554) at org.jgroups.blocks.MessageDispatcher$1.run(MessageDispatcher.java:691) at java.lang.Thread.run(Thread.java:534) This happened on our test cluster. On the production cluster, we saw a similar issue when because of a brief network issue the master failed over. Services that lookup XAConnectionFactory threw a similar exception. I tested with jboss 4.0.4 and the problem still exists -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
