Hi All ,
We are trying to get clustering configured for our application so that
DataService's Destination keep serving the cleint in case of any server
failure . We are using F5 hardware load balancer.
We have set up a default-cluster, using tcp and while creating DataService
Destination we are setting cluster ID as follows
1)
.....
DataNetworkSettings ns = new DataNetworkSettings();
ns.setPagingEnabled("false");
ns.setClusterId("default-cluster")
....
2) service-config.xml
<clusters>
<cluster id="default-cluster" properties="jgroups-tcp.xml"
url-load-balancing="false" />
</clusters>
3) jgroup-tcp.xml - First
<TCP bind_addr="114.19.8.161" start_port="7800" loopback="true"
enable_diagnostics="true"/>
<TCPPING timeout="3000" initial_hosts="114.19.8.226[7800]" port_range="1"
num_initial_members="1"/>
<MERGE2 min_interval="10000" max_interval="20000"/>
3) jgroup-tcp.xml - Seond
<TCP bind_addr="114.19.8.226" start_port="7800" loopback="true"
enable_diagnostics="true"/>
<TCPPING timeout="3000" initial_hosts="114.19.8.161[7800]" port_range="1"
num_initial_members="1"/>
<MERGE2 min_interval="10000" max_interval="20000"/>
I am using Jboss4.2.2 GA and LCDS2.6.1 and we have licensed version of LCDS
I am getting following message on JBoss console : -
04:26:15,296 INFO [STDOUT] [Flex]Cluster node from address 114.19.8.161:7800
joined the cluster for default-cluster

te(StateTransferIntegrator_140.java:100)
Am I missing anything ?
During the testing when I bring down one of the jboss server, It immediately
throws Destination does not exist error
I will appreciate any help on this .
Thanks
