Master node detection

[anubisman]

Hi,

Is it possible to detect which one of nodes in the cluster is the master node???

In my tests I have found that one of my test computers every time becomes the master node and no metter if it is started the first or the second.

Help to find the answer!

Best regards,
Aram.

If you go into ClusterPartition with jmx-console, you see a *view*. The first member of the view is always the master node. If the second node becomes the master node, then the nodes didn't cluster, didn't find each other

Thanks for your response,

But how can I go into ClusterPartition with jmx-console???
I couldn't find something like this in my jmx-console.

What service do you open from jmx-console???

Best regards,
Aram.

1) run.sh -c all
2) in jmx-console: access "jboss:service=DefaultPartition"
3) The attribute is "CurrentView"

Are you talking about this message ???

28.04.06 12:45 : Partition object created
28.04.06 12:45 : Initializing partition
28.04.06 12:45 : Starting partition
28.04.06 12:45 : New view: [10.37.13.52:1099] with viewId: 0 (old view: [10.37.13.52:1099] )
28.04.06 12:45 : setState called on partition
28.04.06 13:02 : New view: [10.37.13.40:1099, 10.37.13.52:1099] with viewId: 1 (old view: [10.37.13.52:1099])

Does this mean that node on IP 10.37.13.40 is the master node???

Best regards,
Aram.

Sorry, but I couldn't find the attribute you said:

3) The attribute is "CurrentView"

Maybe my configuration is not normal????

Could you please send my your clustering configuration files????

Best regards,
Aram.

// Does this mean that node on IP 10.37.13.40 is the master node???

Yes

[belaban]

Use run.sh -c *all*, then you'll see it

[anubisman]

I am sorry,

I'm starting JBoss 4.0.3 on Windows XP.
This kind of command doesn't work on my computers.

Best regards, Aram.

[belaban]

run.bat -c all then

[anubisman]

Thank you very much for your response,

But are you shure that this command is valid, because I'm getting this message

// run.bat: unused non-option argument: then

What is the version of your JBoss???
Maybe this argument is for another version???

Best regards, Aram.
