Hi Friends,
I am using jboss 4.0.5GA
I have the following properties se for my node to enable buddy replication.
<attribute name="BuddyReplicationConfig">
| <config>
| <buddyReplicationEnabled>true</buddyReplicationEnabled>
| <buddyLocatorClass>org.jboss.cache.buddyreplication.NextMemberBuddyLocator</buddyLocatorClass>
| <buddyLocatorProperties>
| numBuddies = 1
| ignoreColocatedBuddies = true
| </buddyLocatorProperties>
|
| <buddyPoolName>default</buddyPoolName>
| <buddyCommunicationTimeout>2000</buddyCommunicationTimeout>
|
| <autoDataGravitation>false</autoDataGravitation>
| <dataGravitationRemoveOnFind>true</dataGravitationRemoveOnFind>
| <dataGravitationSearchBackupTrees>true</dataGravitationSearchBackupTrees>
| </config>
| </attribute>
But when I start two nodes and shutdown one node, the application crashes. Failover does not work.I am not able to understand why.
If I disable buddyclustering and let the session replicate across all nodes
then application clustering works fine for failover.
This is my jboss console log:-
