Cluster Standalone Jboss EAP6

[ivankychung]

Hello,

I installed JBoss EAP6 on two physical nodes (2 different IP). I launch 1 jboss instance with standalone-ha.xml  on each node.

The first instance (named jbc-poc-1) output following warning message, it seems they can failed to form a cluster group.

[org.jboss.as.clustering] (MSC service thread 1-2) JBAS010238: Number of cluster members: 1

.....

[org.jgroups.protocols.TP$ProtocolAdapter] (Incoming-20,shared=udp) dropping unicast message to wrong destination jbc-poc-2/web; my local_addr is jbc-poc-1/web

The second instance  (named jbc-poc-2) also output JBAS010238message but no unicast warning message

[org.jboss.as.clustering] (MSC service thread 1-2) JBAS010238: Number of cluster members: 1

First I though it was UDP is not availiable in our environment but I ‘ve tested UDP communication by using the Jgroup testing program and it is OK. I got the same warning message even I switch Jgroups to using TCP

Is there any configuration need?

Any help is appreciated!

Try the example from https://github.com/akquinet/jbosscc-as7-examples/tree/master/cluster-example and see how it goes.

For Clustering on 2 different m/c follow the below steps:

Note: As both node is on different m/c so there is no need of setting offset.

  1. start the jboss node 1 as follows :

     ./standalone.sh -c standalone-ha.xml -u 230.0.0.4 -Djboss.node.name=node1 -b node1IP

  2. start the node 2 as follows :

     ./standalone.sh -c standalone-ha.xml -u 230.0.0.4 -Djboss.node.name=node2 -b node2IP

Where:

-c = is for server configuration file to be used

-b = is for binding address

-u = is for multicast address

-Djboss.node.name = is for the name of the node

3. as u can the message on both the server console that no. of cluster member=2

4. in order to make clustering testing u have to deploy the application which uses <distributable/> tag in web.xml

now u can test the application by hitting the url :  localhost:8080/myApp
