How to configure JBossCache to commnicate between two nodes

[javakishore]

HI All,

I am planning to use JBoss Cache. I am using JBOSS 3.0.3 version

My problem is:

I have two machines and both running JBOSS 3.0.3

I have written a class (say Class A) which uses JBOSS Cache and using class A in both the machines.

In Machine 1, If I put an object in JBOSS cache through Class A->putObjInCache method, it stores in JBOSS Cache.

But my problem is when JBOSS cache store an object on machine 1 it is not updating the cache on the other machine.

I am using Asynchronous updates on other machines and I am using Asynchronous XML given in JBOSS Cache sample

My questions are:

1. Do I need to make any changes < attribute name="ClusterConfig" >

2. Please provide me a sample code either Java or in XML so that both the machines can communicate each other.


3. Do I need to have mcast_addr="a.b.c.d" same on both the machines
Are their any rules to define mcast_addr IP address?

Please help me I am strucked and not able to use JBOSS Cache to update objects on other machines.

mcast_addr has to be the same on both machines. Additionally the NIC has to setup that multicast works (the route to 224.0.0.0 netmask 240.0.0.0 has to be bound to the NIC and not the local loopback only so the ip-packages actually leave the machine). Just search Google for 'multicast ip' to get more understanding of how ip-multicast works.

given multicast is working on the machnice sample xml-files replSyncService.xml or replAsyncService.xml will work out-of-the box without modification.
