How to know which managed server is currently hosted JMS server byJMX?

[murthypatnaik]

Hi, We have JMS clustering across two managed servers in weblogic 8.1. Initially JMS server is targtted to first managed server. After that, I manually migrated JMS server to second managed server. In this scenario, How to know which managed server is currently hosted JMS server in pogrammatic way using JMX? Thanks in Advance, Murthy P

Does your JMS server expose any JMX methods or a remote listener ?

No, I have mentioned like following
******************
WebLogicObjectName aObjectName = new WebLogicObjectName("JMS0","JMSServer","patnaikJMS");
JMSServerMBean jmsServer = (JMSServerMBean)home.getMBean(aObjectName);
currentServer = jmsServer.getTargets()[0].getName();
System.out.println("JMS hosted server name::"+jmsServer.getTargets()[0].getName());
******************

It is always returning first managed server, even after jms server migration.

Thanks,

I got the solution, Following is the solution..thanks!

**************************************
ServerMBean candidateServer = null;

MigratableTargetMBean migratableTarget = null;

TargetMBean[] targets = jmsServer.getTargets();

if(targets != null && targets.length > 0)

{

boolean hostingServerRunning = false;

boolean candidateServerRunning = false;

if(targets[0] instanceof MigratableTargetMBean)

{

migratableTarget = (MigratableTargetMBean) targets[0];
ServerMBean[] candidates =
migratableTarget.getConstrainedCandidateServers();


if(candidates == null || candidates.length == 0)

candidates = migratableTarget.getAllCandidateServers();


if(candidates != null && candidates.length > 0)
{

ServerMBean hostingServer = migratableTarget.getHostingServer();
System.out.println("hosting server="+hostingServer.getName());
}
}
}
