1) Edit /etc/hosts file and map --LBR Hostname-- to --LBR IP-- on each node 2) Set enableCluster to true and assign a name to the clusterName property in ORACLE_HOME/bpel/system/config/collaxa-config.xml on each node 3) Set mcast-addr and mcast-port in ORACLE_HOME/bpel/system/config/jgroups-protocol.xml on each node 4) Set the soapServerURL to the same value as the load balancer internal URL and the soapCallbackUrl to the same value of the load balancer external URL, using the BPELADMIN console on each node 5) Configure these properties on all the nodes in the cluster: 6) In the ORACLE_HOME/bpel/utilities/ant-orabpel.properties file, set cluster to true. 7) Set oc4jinstancename to SOA_GROUP (the name of the OC4J group that has the Oracle BPEL Process Manager deployed to it). 8) Restart the OC4J_SOA instances on all nodes.

a) Use Discovery Server method for OPMN Cluster b) Designate --node1-- as the discovery server and apply the below configuration c) Edit opmn.xml file and the below config --notification-server-- --topology-- --discover list="--node1:--ONS_Port--"/-- --/topology-- ... --/notification-server-- d) Run the command ./opmnctl reload Apply the step a to d on all the nodes. e) After doing on all nodes , execute :- ./opmnctl startall and thus opmn gets clustered
